Siemens RCD, 4-pole, Type B, time-delayed, In: 40 A, 300 mA, Un AC: 400 V. The RCD is the residual current protective device for touch protection. Siemens' patented residual current protective devices are an essential part of the SENTRON protection components for electrical installations, as they prevent life-threatening electrical accidents by safely disconnecting dangerous fault currents to ground. Electrically ignited fires can be prevented right from their inception. Whether through direct contact with live parts or indirect contact with operating equipment – protection is primarily achieved through rapid disconnection.

The Siemens RCDs 5SV are characterized by:
1. Comprehensive protection for persons and property against electric shock.
2. Whether sinusoidal alternating fault currents or smooth direct fault currents – Siemens offers the right type for all requirements, as well as special versions.
3. Reliable safety during installation thanks to standard integrated gripping and touch protection.
4. Tool-free removal from the DIN rail or busbar connection through convenient slider manual operation.
5. The data matrix code on the front of the device provides quick and easy access to all information regarding the RCD.
6. Be compliant with standards: The residual current protective devices meet the requirements of DIN VDE.
7. Optimal technology for your safety – exclusively from Siemens.
