Product Positioning

The Siemens SENTRON 5SM2645-0 is a 4-pole leakage current protection module (RC Unit) with a rated current of 63A and Type AC operating characteristics. It does not have overcurrent protection and must be used in combination with a miniature circuit breaker.

Core Product Advantages and Features

63A medium current specification

With a rated current of 63A and a 4-pole structure, it is suitable for leakage protection in general medium-sized power distribution circuits.

Type AC Action Characteristics

It detects only pure sinusoidal AC leakage current and is suitable for general circuits with simple AC loads.

Modular assembly design

When combined with a compatible miniature circuit breaker, residual current protection can be added without modifying the existing circuit breaker.
