LOCKING DEVICES

“Safe OFF“ switch-independent interlock device to prevent unauthorised closing This special feature available for draw-out circuit breakers prevents closing independently of the switch, thus satisfying main switch conditions to EN 60204 (VDE 0113) - Mains disconnecting equipment. Unauthorised closing is not possible after replacement of the circuit breaker. The circuit breaker must be switched off to activate the interlock. The interlock device is bloc ked when the circuit breaker is switched on. The blocking is only effective when the key has been removed. The safety key can only be removed in the “OFF” position.

LOCKING MECHANISMS

Locking device against moving if the cubicle door is open for withdrawable circuit-breakers

The crank handle is blocked if the cubicle door is open and cannot be withdrawn. It is not possible to move withdrawable circuit-breakers. The blocking is only effective if the crank handle is inserted.

Interlocking of cubicle door

The cubicle door cannot be opened if the

  • fixed-mounted circuit-breaker ist closed (transmission of the locking signal by means of Bowden wire) or
  • if the withdrawable circuit-braker is in connected position

MECHANICAL INTERLOCK

Mutual mechanical circuit-breaker interlocking

The module for mutual mechanical interlocking can be implemented for two or three circuit-breakers and is simple to adapt to the respective version. Fixed-mounted and withdrawable circuit-breakers are compatible and can be implemented together in a single system.

The circuit-breakers can be installed either next to one another or on top of one another, whereby the distance between circircuit- breakers is determined only by the lenght of the Bowden wire.

SIGNALISATION AND CONTROL

  • Ready-to-close signalling switch
    • MO circuit breaker come with a visual ready-to-close signal indicator as standard. The option is also available to indicate ready-to-close using a signalling switch. This signalling switch is included as standard for switches operated via a communications interface.
  • Signalling switch for auxiliary release
    • One signalling contact is available per auxiliary release for polling switch status of the auxiliary releases.
  • Tripped signal switch
    • In the event that the circuit breaker tripped due to an overload, short-circuit, earth-fault or extended protection function, this can be indicated with a tripped signal switch. This indicator switch is available as an option. This signalling switch is indcelud as standard for circuit breakers operated via a communications interface.
  • Operating cycle counter
    • A 5-digit operating cycle counter is available in connection with the motor operator. The counter increments by “1” once the storage spring is fully charged.
  • “Electrical ON“ button
    • Used for the electrical switch-on of the circuit breaker via a local, electical “ON” or remote operation.
  • Sealable cap covers “Electrical ON” button
    • The “Electrical ON button” comes with a sealable cap as standard.
  • Motor cut off switch
    • Rotary switch for switching off (automatic charging) of motor operator.
