Siemens SENTRON Miniature Circuit Breaker 2A, 4-Pole, C Curve, 10kA – 5SL4402-7RCZ12

Product Description

The Siemens 5SL4402-7RCZ12 is a SENTRON Miniature Circuit Breaker (MCB) designed for reliable overload and short-circuit protection in electrical distribution systems. It features a 2 A rated current, 4-pole configuration, C tripping characteristic, and 10 kA breaking capacity, making it suitable for control circuits, distribution boards, industrial panels, and commercial electrical installations. Siemens specifications confirm the 4-pole, C-curve, 2 A configuration and 10 kA breaking capacity.

The MCB operates at 415 V AC, 50/60 Hz, with a maximum multi-phase operating voltage of 440 V AC. It provides energy limitation Class 3, IP20 protection with connected conductors, and a typical mechanical service life of 10,000 operating cycles.
