Vmax ANSI version versus IEC version: Shunt tripping releases suitable for “3 cycles” interruption Wiring with UL certified cables (& AWG cross-section) Nameplate with ANSI parameters Mechanical indicators according to ANSI STDs (symbol & colour) Specific Manual Booklet

Vmax Overview Open/close aux. contacts (standard set of ten aux.c.) Additional opening release Locking magnet in the actuator Opening pushbutton Closing pushbutton Shunt tripping release Built-in lever for closing spring manual charging Undervoltage release (missing in the picture) Shunt closing release Signalling device for closing springs charged/discharged Mechanical operation counter Geared motor for closing spring charging

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 VD4 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 VD4 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 VD4, Vmax cannot be fitted with: Transient contact with momentary closing during circuit breaker opening Motorized truck
