CHINT AL-X3 Alarm Contact

CHINT AL-X3 Alarm Contact,
is an auxiliary signaling device designe for use with NXB-125 series circuit breakers. It provides remote indication of circuit breaker status (ON/OFF/trip) to improve monitoring and safety in electrical systems. When integrate, it signals whether the breaker is manually opene or trippe due to a fault. Built to IEC 60947-5-1 standards, the AL-X3 offers a 10,000-cycle lifespan, high contact reliability, and compact modular design for easy DIN-rail installation.
