Accessories
Push Button Locking Device (VBP)
This device prevents local manual operation of the circuit breaker by covering the opening and/or
closing the push buttons. This locking device can be locked by a padlock or a sealing lead.
Open Position Lock (VSKA)
A key interlock that locks the circuit breaker in the open position by holding the push button in its
depressed position. The key interlock is provided.
Door Interlock (VPEC)
This lock prevents the compartment door from being opened when the circuit breaker is in the
connected position. If the circuit breaker is put into the "connected" position with the door open, the
door can be closed without disconnecting the circuit breaker.
Note: For greater protection, this interlock can be used with racking interlock (VPOC) below.
Racking Interlock (VPOC)
This lock prevents racking in the circuit breaker when the door is open. (Insertion of the circuit
breaker racking crank is not possible when the compartment door is open.)
Disconnected Position Locking
The circuit breaker can be locked in the disconnected position by means of one to three padlocks
(padlocks not provided) or one key interlock (factory-mounted option VSKC). The key interlock is on
the stationary assembly and accessible with the cubicle door locked.
Note:

Key interlock is of the captive key type, free when locked.

By special order, locking may be possible on disconnected, test and connected positions
(VSKEC).
Spring Charge Interlock (VEAA)
This selection is for a device that prevents the circuit breaker or switch from being fully withdrawn
from its cradle when the closing spring is charged. It is standard for ANSI (UL1066) circuit breakers
and an option on others. The VEAA interlock is not compatible with undervoltage releases (MN,
MNR or MNRI).
