Siemens Residual current operated circuit breaker, 2-pole, 40A, 30mA Part number 5SV3314-6

Product Overview

The Siemens SENTRON 5SV3314-6 is a 2-pole residual current circuit breaker (RCCB), Type A, rated at 40 A with a residual current trip threshold of 30 mA (AC). The device is designed for AC mains of 230 V and provides protection against earth fault currents including pulsating DC. Its compact width and robust build make it suitable for modern installations in residential, commercial, and light industrial environments.
