OF Auxiliary Contact Circuit Breaker Accessory

The Compact Auxiliary Contact Module for Circuit Breakers is a precision-engineered accessory designed to provide real-time status indication for miniature circuit breakers in low-voltage distribution systems. This OF-type auxiliary contact features a snap-on mounting mechanism that enables rapid, tool-free installation directly onto compatible circuit breakers, eliminating the need for panel modifications or additional wiring. Its compact modular footprint saves valuable space inside electrical enclosures, while the rugged flame-retardant housing ensures dependable performance under vibration, temperature variations, and mechanical shock commonly found in industrial environments. The contact operates passively, drawing no external power, which reduces energy consumption and simplifies system integration. Rated for 3A at 380V~/415V~ AC and 1A at 110V~/125V~ DC, the module provides clear Normally Open and Normally Closed contact states through well-marked terminals (11, 12, 14), facilit…
