Why Choose the Lovato P1RD2P63A300S Selective Residual Current Circuit Breaker?
The Lovato P1RD2P63A300S is a 2-pole selective residual current circuit breaker (RCCB) designed to provide dependable earth leakage protection with time-delayed selective tripping. As part of the Lovato P1RD series, it combines Type A residual current detection with Type S selectivity, making it suitable for coordinated protection in industrial, commercial and electrical distribution systems.
Rated at 63 A with a selective rated residual current of 300 mA, the P1RD2P63A300S uses a Type A selective characteristic. Type A operation enables detection of sinusoidal alternating and pulsating DC residual currents, while its Type S time-delay characteristic is designed to support selectivity with downstream residual current protection devices.
The P1RD2P63A300S operates at 230 V AC and 50/60 Hz, with a 10 kA short-circuit rating and 10 kA rated conditional short-circuit current. Its two-pole, two-module construction mounts directly onto a standard 35 mm DIN rail, providing a compact solution for coordinated residual current protection in distribution boards and electrical control systems.

Selective Type A Residual Current Protection
Selective residual current circuit breakers such as the Lovato P1RD2P63A300S provide time-delayed residual current protection for electrical distribution systems where coordination between upstream and downstream protective devices is required. The Type S selective characteristic delays operation so that an appropriately coordinated downstream residual current device can clear a localised earth leakage fault before the upstream RCCB disconnects a larger section of the installation.
The Type A characteristic enables detection of both sinusoidal alternating residual currents and pulsating DC residual currents that can occur with electronic equipment. Combined with its 300 mA selective sensitivity, 63 A current rating and Type S time delay, the P1RD2P63A300S is well suited to appropriately designed distribution systems requiring selective residual current protection. As an RCCB, it should be coordinated with suitable overcurrent and short-circuit protection.
Typical Applications
- Industrial and commercial electrical distribution boards.
- Upstream residual current protection requiring Type S selectivity.
- Circuits requiring 300 mA selective residual current protection.
- Distribution systems with downstream residual current protection devices.
- Electrical circuits supplying equipment capable of producing pulsating DC residual currents.
- Industrial machinery and automation distribution systems.
- OEM electrical cabinets and power distribution equipment.
