MCB 63A, 2P, 415V AC – 5SL4263-7RC

Product Description

Siemens SENTRON MCB – 63A, 2P, 415V AC – 5SL4263-7RC

The Siemens 5SL4263-7RC is a SENTRON series miniature circuit breaker (MCB) designed to provide reliable protection of electrical circuits against overload and short-circuit faults in industrial, commercial, and residential low-voltage distribution systems.

It is widely used in distribution boards, control panels, feeder circuits, and general power applications operating on 240/415V AC systems. This 2-pole MCB features a C-curve tripping characteristic, making it suitable for circuits with moderate inrush currents such as small motors, transformers, HVAC loads, and mixed electrical systems.

With a 10kA breaking capacity, it ensures fast and safe disconnection during fault conditions, improving system safety and equipment protection.
