General data
The vacuum circuit-breakers consist of aprimary and a second-ary part. The relevantdata make up the 16-digit Order No.
The primary part contains the principalelectrical data of thebreaker poles.
The secondary part covers the auxiliary devices which are ne-cessary for operatingand controlling the vacuum circuit-breaker.
Additional equipment
One item of additionalequipment is coveredby one order code.When an order is placed, this should bestated together withthe Order No.
Several types of addi-tional equipment canbe ordered at the sametime, i.e. several ordercodes can be added to the Order No. in succession and in anysequence.
In the case of furtheradditional equipmentwhich cannot be or-dered by means of theorder codes, the OrderNo. must be suffixedby “–Z”, the ordercode Y99 and the itemstated in plain text inaddition (prior consul-tation with departmentEV MNK V in Erlangenis required).

Accessories and spare parts
Installation parts
When releases / solenoidsare being retrofitted, theOrder Nos. of the installationparts must also be stated.With other types of additionalequipment, the requiredinstallation parts are includedin the delivery.
Spare parts
When releases / solenoidsare required as spare parts,the Order No. and designof the appropriate standardcircuit-breaker must bestated.Fixings elements, installationinstructions or circuit dia-grams are supplied with allspare parts, if required.
Ordering note
The order numbers areapplicable to standard circuit-breakers of current manu-facture. When installation orspare parts are being orderedfor an existing standardcircuit-breaker, always quotethe serial No. of the breaker(see “Rating plate” on page1/3) in order to be certain ofobtaining the correct items.

When releases / solenoidsare being retrofitted, theOrder Nos. of the installationparts must also be stated.With other types of additionalequipment, the requiredinstallation parts are includedin the delivery.
Spare parts
When releases / solenoidsare required as spare parts,the Order No. and design ofthe appropriate frequent-operation circuit-breakermust be stated.Fixings elements, installationinstructions or circuit dia-grams are supplied with allspare parts, if required.
Ordering note
The order numbers areapplicable to frequent-operation circuit-breakers ofcurrent manufacture. Wheninstallation or spare parts arebeing ordered for an existingfrequent-operation circuit-breaker, always quote theserial No. of the breaker (see“Rating plate” on page 1/3)in order to be certain ofobtaining the correct items.

Accessories and spare parts
Installation parts
When releases / solenoids arebeing retrofitted, the Order Nos.of the installation parts must alsobe stated. With other types ofadditional equipment, therequired installation parts areincluded in the delivery.
Spare parts
When releases / solenoids arerequired as spare parts, the OrderNo. and design of the appropriatehigh-current circuit-breaker mustbe stated.Fixings elements, installationinstructions or circuit diagramsare supplied with all spare parts,if required.
Ordering note
The order numbers are applicableto high-current circuit-breakersof current manufacture. Wheninstallation or spare parts arebeing ordered for an existinghigh-current circuit-breaker,always quote the serial No. ofthe breaker (see “Rating plate”on page 1/3) in order to be certainof obtaining the correct items.

As spare parts the vacuum interrupters are alwayssupplied with adapter.
For the selection of the correct spare vacuuminterrupter, it is necessary to statethe design code and the serial No.of the high-current circuit-breaker. Both arestated on the rating plate of the high-currentcircuit-breaker.
Complete exchange of vacuum interrupters6 vacuum interrupters are required for the externalpole assemblies of a high-current circuit-breakerand only 3 vacuum interrupters for the centralpole assemblies.
