MCB 4A, 4P, 415V AC – 5SL6404-7RC

Product Description

Siemens SENTRON MCB 4A, 4P, 415V AC – 5SL6404-7RC

The Siemens 5SL6404-7RC is a SENTRON 5SL6 series Miniature Circuit Breaker (MCB) designed to provide reliable protection for electrical circuits against overload and short-circuit faults. This 4-pole, 4A MCB is ideal for three-phase + neutral distribution systems, especially in industrial control panels, automation systems, and low-load power circuits where precise protection is required.

It ensures safe operation of sensitive loads and helps maintain stability in LT distribution boards, PLC panels, and instrumentation systems.
