Doepke 09431502 DRCCB 5 ST 040-4/0.03-A 4-pole 40/0.03A residual current circuit breaker

Residual current circuit breakers (RCCB) are components for implementing the protective measure 'protection by automatic shutdown of the power supply' in accordance with the requirements of 0100 Part 410 or corresponding international installation regulations. Devices in the DRCCB 5 series are compact two-pole or four-pole residual current circuit breakers with additional equipment. Switches with residual current characteristic A enable the detection of sinusoidal alternating and pulsating direct residual currents independent of the mains voltage. Any additional functions that may be present are voltage-dependent. DRCCB 5 in the self-test version enable an uninterrupted, automatic and regular function test of the residual current circuit breaker. The power supply is integrated in the device and is provided without any additional parts via the supply lines from above. The automatic function can be switched on and off using the switch slide. Features: - monthly self-test - LEDs indicate the operating status - configurable auxiliary contact Installation type: - quick attachment to mounting rail - installation position as desired - power supply from above Areas of use: The devices are used wherever electrical installations are difficult to access or where a high level of system availability is required. This can be, for example, agricultural operations, small wind turbines, pumping stations, sewage treatment plants and telecommunications systems.
