Why Choose the Lovato P1RD4P63A030 Residual Current Circuit Breaker?
The Lovato P1RD4P63A030 is a four-pole residual current circuit breaker (RCCB) designed to detect earth-leakage currents and disconnect the protected circuit when the residual current reaches its operating threshold. Part of the Lovato P1RD series, it provides Type A residual-current protection for three-phase electrical distribution, industrial control and equipment applications.
Rated at 63 A with a rated residual operating current of 30 mA, the P1RD4P63A030 provides high-sensitivity residual-current protection. Its Type A characteristic responds to sinusoidal AC and pulsating DC residual currents, making it suitable for modern circuits where these residual-current waveforms may occur.
The P1RD4P63A030 operates at 230/400 V AC and 50/60 Hz, occupies 4 DIN modules and mounts on standard 35 mm DIN rail. With a 10 kA rated conditional short-circuit current, IP20 frontal protection and compliance with IEC/EN/BS 61008-1, it is engineered for professional electrical installations.

Reliable Type A Residual-Current Protection
The Lovato P1RD4P63A030 monitors the current balance through the active conductors of the protected circuit. If leakage to earth produces a residual-current imbalance reaching the 30 mA operating threshold, the RCCB disconnects the circuit, providing residual-current protection for appropriately designed installations.
Its Type A characteristic provides detection of both sinusoidal AC and pulsating DC residual currents. Combined with a 63 A rating, four-pole configuration and 230/400 V AC operating voltage, the P1RD4P63A030 is well suited to modern three-phase distribution and industrial electrical systems requiring Type A protection.
Typical Applications
- Three-phase electrical distribution boards.
- Industrial control and power panels.
- Machine and equipment electrical systems.
- Commercial and industrial electrical installations.
- Circuits containing compatible electronic equipment.
- Applications requiring 30 mA Type A residual-current protection.
