10. Device for monitoring the functionality and continuity of the shunt opening/closing releases (STU Shunt Test Unit)

The STU device can be used in conjunction with the shunt opening release (-MBO1; -MBO2) or shunt closing release (-MBC) for functionality and continuity tests (one device for each release to be tested). The testing/monitoring Shunt Test Unit can be used to test the continuity of releases with rated operating voltage between 24 V and 250 V (AC and DC), as well as the functionality of the release’s electronic circuit. The continuity test is performed in cycles with a 20-second interval between one test and the next. The unit has optical LED indicators on the front. The following information is given:– POWER ON: power is being supplied– -MO/-MC TESTING: the test is being performed– TEST FAILED: this signal is given after a test has failed or

when there is no auxiliary power being supplied– ALARM: this signal is given after three consecutive tests

have failed.

9. Padlock device for the opening and closing pushbuttons

Allows the opening and closing pushbuttons to be locked with up to three 4-mm diameter padlocks (not supplied). This locking system is available in three versions:9A Locking of both pushbuttons without distinction9B Separate locking of the opening and/or closing

pushbuttons9C Locking for HD4/RE-Sec circuit-breakers without

distinction

NOTE. Lock 9A prevents closing by remote control; lock 9B does not prevent closing by remote control.
