The CNC YCB7-63N 1P C40 miniature circuit breaker is engineered to protect electrical circuits from overloads and short circuits. With a 40A rated current and C-type tripping curve, it is suitable for circuits with moderate inductive loads such as HVAC systems, water heaters, and industrial sockets.
Operating at 230/400V AC, 50/60Hz, this breaker features a thermal-magnetic release mechanism and complies with IEC/EN 60898-1 standards. It mounts easily on a DIN rail, supports top or bottom wiring, and offers IP20 protection. Commonly used in residential, commercial, and light industrial environments.
