Ensure operational safety and prevent accidental switching with this mechanical bypass lock designed specifically for the NXB-63 (LMI-XB) circuit breaker. This lock provides a robust physical barrier, ideal for maintenance procedures or situations requiring a locked-out, tagged-out (LOTO) state. It's a crucial safety component for electrical systems.

The OUVT-X1 is an auxiliary contact designed for use with NXB-63 series circuit breakers. This contact provides remote indication of the breaker's status – whether it has tripped (open) or is in the closed position. It's easily connected to the left side of the NXB-63 breaker, enabling reliable remote monitoring of circuit conditions. Ideal for applications requiring remote status awareness.

The OVT-X1 is an auxiliary contact designed for use with NXB-63 series circuit breakers. This contact provides remote indication of the circuit breaker's status – whether it's open or closed – enabling efficient monitoring from a distance. It’s easily attached to the left side of the NXB-63 breaker for simple installation and reliable performance. Ideal for applications requiring remote status verification.

The AX-X1 auxiliary contact is designed for use with NXB-63 series circuit breakers. This contact provides remote indication of the circuit breaker's status – whether it's open or closed – enabling efficient monitoring and control from a distance. It's easily attached to the left side of the NXB-63 breaker.

The SHT-X1 is an auxiliary contact designed for use with NXB-63 series automatic circuit breakers. This contact provides remote indication of the breaker's status – whether it's open or closed – enabling efficient monitoring and control from a distance. It easily connects to the left side of the NXB-63 breaker.
