MCB 20A, 3P, 415V AC – 5SL4320-7RC

Product Description

Siemens SENTRON MCB – 20A, 3P, 415V AC – 5SL4320-7RC

The Siemens 5SL4320-7RC is a SENTRON series miniature circuit breaker (MCB) designed for reliable protection of low-voltage electrical distribution circuits against overload and short-circuit faults. It is widely used in industrial panels, control systems, and building distribution boards for safe and efficient power distribution.

This 3-pole MCB operates on 240/415V AC systems and features a C-curve tripping characteristic, making it suitable for general-purpose applications with moderate inrush currents such as small motors, control transformers, and auxiliary circuits.

With a 10kA breaking capacity, it ensures fast fault isolation and protects wiring and connected equipment from electrical damage.
