Self-reclosing earth leakage relayREC2

FeaturesDescription

REC2 is a 2 or 4-pole earth leakage switch associated to a compact motor and control set that enables the automatic and safe re-closure of the installation, provided that the leakage is not permanent. Output contact available in REC2C model

The earth leakage switch is reclosed auto-matically, in accordance with the work mode selected (switch on the front):

}} Time sequence mode: after a switch trip, REC2 will make 6 reclosing attempts, with a timer set at 10, 20, 30, 60, 120 and 600 s. If the set can not be reclosed, it will be blocked in a trip status until it is reset manually.}} Insulation monitoring mode: after the

switch trip, REC2 repeats the previous se-quence, but it measures the presence of leak-age current in the installation before carrying out the reset. REC2 will only reclose when the insulation measurements are correct.

There are LEDs on the front part of the con-trol module to indicate the operation status:

}} Manual or automatic reclosure}} Reclosure mode selected}} Reclosing status}} Lock status

Drop-down window to activate/deactivate the automatic reclosure of the earth leakage switch.

Application

Said relays are connected to a contactor or similar element to guarantee the level of self-reclosing earth leakage protection after a trigger. It is very easy to install, so that it is the adequate solution for installations that require the use of earth leakage protection systems as a result of their location or posi-tion in a determined site, which makes them hard to supervise or access: lighting panels, telephony installations, television repeaters, refrigeration chambers, etc.

Showing the value of the leak instantane-ously on the display with the pre-alarm in-dications provides the information about the state of lines being protected, thus allowing the implementation of an adequate preven-tive maintenance approach.

In addition, RS-485 communications are used with the PowerStudio software, which allows the centralised supervision of the sys-tem in real time, with a record log that can be analysed later on.

Application

MCB are the perfect elements to guaran-tee self-reclosing earth leakage and over-load protection applications, connected to WRKRT-25 relays.

FeaturesDescription

MCB-P or MCB-T are circuit-breakers that combine the functions of a circuit breaker (overload and short-circuit protection) and those of a contactor on the same element.

There are two options with MCB:

}} Closed circuit-breaker: Allows remote control functions (contactor function). It can be disconnected and reconnected electrically with the adequate signal.}} Circuit-breaker opened by an overload or

short-circuit trip or by manual disconnection: remote control reset is not allowed, only ma-nually.

The remote control function works on the same contacts as those of the circuit break-er, guaranteeing the disconnection in each case.

The MCB-T type includes a remote con-trol module with two auxiliary, potential free (three-wire) contacts that indicate the status of the MCB at the input of the remote con-trol (contactor function) and/or the circuit breaker.

They are also used as circuit breakers linked to CIRCUTOR self-reclosing relays.

They are an essential accessory for protec-tion and automatic circuit breaker and earth leakage reclosing system

FeaturesDescription

The RECmax MP series are motorized circuit breakers that can be linked remotely.

They function as protection against short-circuit and overload, and can also be used as a circuit breaker.

After a disconnection caused by a circuit breaker, the switch can be reconnected through an external order. It has two inputs that act through voltage-free external signals, ordering the opening (input O) and subse-quent closing (reclosing system) of the auto-matic switch (input I) . It also has two single-contacts outputs for signalling the status and the cause of the opening and closing of the automatic switch (trip, manual/Test).

Application

The MT-FDE Series is composed of motor-ized circuit breakers that can be activated remotely and can be used in any application that uses a connection/disconnection remote control.

They are also used as circuit breakers as-sociated to the self-reclosing relays, for ex-ample, RGU-10 MT orRRM. They are a vital accessory in the self-reclosing overload and earth leakage protection process.

FeaturesDescription

Automatic switch with remote control of the MT-FDE Series, for currents of 80 to 250 A, 3 and 4 poles.

Responsible for the protection against short-circuits and overloads, but also used as a circuit breaker.

The switch can be reclosed with two me-thods, depending on the adjustment of the motor group in the operations mode:

}} “MANU”: executed manually with the same switch, following the OFF and ON se-quence.}} “AUTO”: carried out with an electrical im-

pulse, following the OFF and ON sequence.

Application

The WRGMT groups can be used to make safety compatible with the continuity of the service in remote installations or installations that do not have the usual maintenance staff. They guarantee the overload and earth leak-age protection with a self-reclosing system after a trigger, both in the case of an earth leakage and overload trip.

It is a very good solution in installations in special locations that are hard to monitor and guard: telephony installations, television re-peaters, refrigeration chambers, etc.

Description

The WRGMT group acts as an overload (overload + short-circuit) and earth leakage protection system with earth leakage and overload reclosure.

The nominal current of the overload protec-tion is determined by the type of MT (up to 63 A) or MT-FDE used.

The group is composed of the following ele-ments:

}} RGMT relay (earth leakage protection)}} Motorized automatic switch of the MT-

FDE Series or motorized circuit breaker of the MT Series, with overload protection and circuit breaker functions}} Earth leakage transformer, WG

Application

The RECmax MP series are motorized circuit breakers that can be reset automatically or controlled remotely, apt for any application in which remote connection/disconnection con-trol is required.

They are an essential accessory for protec-tion and automatic circuit breaker and earth leakage reclosing system, and for external connection/disconnection control.

Features

Description

The RECmax P series are 2- and 4-pole cir-cuit breakers connected to a compact motor and internal control unit that enables auto-matic reclosing system.

After triggering, the switch reconnects follow-ing a sequence of 3 reconnections, with 3 minutes between resets. If the unit is not able to reconnect after 3 attempts, it remains trig-gered until a manual or remote reset is made.

They can also be connected remotely to an external control. It has two inputs that through voltage-free external signals, order the open-ing (input O) and subsequent closing (reclos-ing system) of the automatic switch (input I) .

They function as protection against short-circuit and overload, and can also be used as a remote circuit breaker.

The switch status is indicated by LED signals on the device’s front panel. An green ON LED indicates that the device is in service; a red OFF LED indicates that the device is triggered.

A TEST/RESET of the device can be per-formed by pressing a button to check the trig-gering and then reset the device.

It also has two single-contact outputs for sig-nalling the status and the cause of the open-ing and closing of the automatic switch (trig-ger, manual/Test).

Application

The RRM relays can be used in all applica-tions that require a self-reclosing motorized circuit breaker after a trigger or with the use of remote control systems. It has been specially designed to work with the circuit breakers of the MT or MT-FDE Series.

FeaturesDescription

Self-reclosing electronic relay of motorized circuit breakers.

The relays of the RRM series can be used to control, send remote signals and for the remote control of the associated motorized circuit breaker (MT or MT-FDE Series).

The RRM relay has the following functions:

}} Motorized circuit breaker control:}y Automatic reclosing}y Remote connection/disconnection (non-

reclosing)}} Signalling:}y Local, with LEDs}y Remote signalling with relay of the re-

closing lock (in RRM-P)}y RS-485 Communications (in RRM-C)}} Remote control of the automatic switch

The complete reclosing group is composed of the following elements:

}} Motorized circuit breaker of the MT or MT-FDE Series (2 or 4 poles)}} Control relay RRM.
