SENTRON Residual Current Unit – 5SM2322-0RC

Product Description

Siemens SENTRON Residual Current Unit – 5SM2322-0RC

The Siemens 5SM2322-0RC is a SENTRON Residual Current Unit (RC Unit) designed to provide earth leakage (residual current) protection when combined with compatible Siemens MCB systems (5SY series). It enhances electrical safety by detecting leakage currents and automatically disconnecting the circuit to prevent electric shock, equipment damage, and fire hazards.

This unit is commonly used in industrial distribution boards, commercial installations, and residential protection systems where additional residual current protection is required alongside standard MCBs.
