Why Choose the Lovato P1RD4P40A300S Selective Residual Current Circuit Breaker?
The Lovato P1RD4P40A300S is a 4-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 three-phase electrical distribution systems.
Rated at 40 A with a selective rated residual current of 300 mA, the P1RD4P40A300S uses a Type A selective residual operating characteristic. Type A operation enables detection of sinusoidal alternating and pulsating DC residual currents, while its Type S time-delay characteristic supports selective coordination with appropriately specified downstream residual current protection devices.
The P1RD4P40A300S has a rated operational voltage of 230/400 V AC at 50/60 Hz, together with a 10 kA short-circuit rating and 10 kA rated conditional short-circuit current. Its four-pole, four-module construction mounts directly onto a standard 35 mm DIN rail, providing a compact solution for coordinated residual current protection in three-phase distribution boards and electrical control systems.

Selective Type A Residual Current Protection
Selective residual current circuit breakers such as the Lovato P1RD4P40A300S 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, 40 A current rating and four-pole configuration, the P1RD4P40A300S is suited to appropriately designed three-phase distribution systems requiring selective residual current protection. As an RCCB, it should be coordinated with suitable overcurrent and short-circuit protection.
Typical Applications
- Three-phase 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 three-phase power distribution equipment.
