Vmax
Other accessories, on request

• Motorgear for closing spring charging
• Signalling contact closing spring charged
• Signalling contact closing spring discharged
• Locking magnet in the truck to prevent racking-in
  with auxiliary circuits disconnected (for
  withdrawable c.b.)
• Transmitted contacts in the truck for signalling
  inserted or isolated circuit breaker (for
  withdrawable c.b.)
• To prevent racking-out/in with the circuit
  breaker closed and to prevent closing operation
  during the translation, interlock for fixed
  circuit breaker which is converted in
  withdrawable ones by the customer
