5SV5346-0 Siemens RCCB | 3-Phase Residual Current Circuit Breaker

Product Description / Overview

The Siemens 5SV5346-0 is a SENTRON residual current circuit breaker (RCCB) designed for 3-phase installations.
It provides reliable protection against earth leakage currents that can cause electric shock or fire hazards.

This 4-pole device features Type A detection, ensuring both AC and pulsating DC fault currents are identified.
Moreover, the 30 mA sensitivity offers personal protection, while DIN rail mounting allows easy integration into standard distribution boards.

Although RCCBs do not provide overcurrent protection, they work effectively alongside MCBs to deliver complete circuit safety.
Therefore, the 5SV5346-0 is ideal for residential, commercial, and industrial electrical systems.
