Why Choose the Lovato P1RD4P63A300S Selective Residual Current Device?
The Lovato P1RD4P63A300S is a high-performance selective residual current device (RCCB) designed to provide reliable earth leakage protection in industrial, commercial and low-voltage electrical installations. Part of the Lovato P1RD residual current device series, it provides selective tripping characteristics to improve system coordination and minimise unnecessary disconnections.
This four-pole selective residual current device monitors electrical circuits for leakage currents and disconnects the supply when a fault condition exceeds the specified threshold. Its selective operation allows improved discrimination between upstream and downstream protective devices, helping maintain continuity of service in larger electrical systems.
With a rated current of 63 A, a residual operating current of 300 mA and selective operation, the P1RD4P63A300S is suitable for three-phase electrical installations requiring coordinated residual current protection.

Reliable Selective Protection for Electrical Systems
Selective residual current devices such as the Lovato P1RD4P63A300S are designed to improve electrical system reliability by coordinating protection between multiple RCDs. The selective time delay helps ensure that only the faulty section of an installation is disconnected, reducing unnecessary interruptions.
The P1RD series provides engineers, installers and panel builders with dependable residual current protection solutions for complex low-voltage distribution networks where system continuity and safety are essential.
Typical Applications
- Industrial electrical distribution systems.
- Commercial power distribution boards.
- Main switchboards and sub-distribution panels.
- Three-phase electrical installations.
- Control panels requiring selective protection coordination.
- Low-voltage systems requiring earth leakage monitoring.
