Vmax Overview

Vmax Fields of application § Power distribution § Cable control and protection § Overhead control and protection § Transformation and distribution substations § Motor and transformer control and protection § Generator control and protection § Capacitor bank control and protection

Vmax Strenghts § Application where space saving is a premium § Compact dimensions compared to existing VD 4 § Freestanding vacuum interrupters § Moulded case design

Vmax Features § Vacuum interruption technique § Contacts in vacuum protected against oxidation and contamination § Sealed for life vacuum interrupters § Vacuum interrupters and EL mechanical actuator already used and tested in new VD 4 series § Limited switching energy § 10, 000 mechanical operations § Stored energy operating mechanism with built-in anti-pumping device and closing spring charging lever § Insulating monobloc § Operating mechanism and monobloc fixed to a sturdy metal frame § Easy customization with a complete range of accessories § Locks to prevent incorrect and hazardous operations

Vmax Standard equipment § Mechanical signalling device for CB open/closed § Mechanical signalling device for closing spring charged/discharged § Opening and closing pushbuttons § Mechanical operation counter § Built-in lever for manually charging of closing spring § Anti-pumping mechanical built-in function § 5 + 5 auxiliary contacts § Connection terminals and terminal board for auxiliary circuits (for fixed CB) § Isolating contacts, cord with connector (plug only), racking-in/out lever (for withdrawable CB)

Vmax Other accessories, on request § Shunt tripping release § Additional shunt tripping release § Shunt closing release § Opening solenoid (for self-supplied overcurrent relay ABB PR family) § Undervoltage release § Electronic time delay (which must be mounted externally in relation to the circuit breaker) for undervoltage release § Mechanical override for undervoltage release § Opening and closing pushbuttons protection § Opening and closing pushbuttons padlock § Key-lock in open position § 5 extra auxiliary contacts

Vmax Other accessories, on request § Motorgear for closing spring charging § Signalling contact closing spring charged or signalling contact closing spring discharged § Locking magnet in the truck to prevent racking-in with auxiliary circuits disconnected (for withdrawable CB only) § Transmitted contacts in the truck for signalling inserted or isolated circuit breaker (for withdrawable CB only) § Interlock for fixed circuit breaker which is converted in withdrawable ones by the customer (to prevent racking-out/in with the circuit breaker closed and to prevent closing operation during the translation)

Vmax Compared to VD 4, Vmax cannot be fitted with: § Transient contact with momentary closing during circuit breaker opening § Motorized truck
