Description

Optional padlocks can be used to lock the MasterPacT MTZ2/MTZ3 circuit breaker in the open position. When locked the circuit breaker cannot be closed, either locally with the closing pushbutton, or remotely.

To use padlocks to lock the circuit breaker in the open position, an optional OFF-position locking accessory is necessary. This accessory allows the use of up to three padlocks with shackle diameter 5–8 mm.

NOTE: This accessory is not compatible with VSPO OFF-position keylock accessory. The two accessories cannot be used at the same time.
