Why Choose the Lovato P1RD4P25A030 Residual Current Circuit Breaker?
The Lovato P1RD4P25A030 is a four-pole Type A residual current circuit breaker (RCCB) designed to provide residual-current protection in industrial, commercial and electrical distribution systems. Part of the Lovato P1RD range, it combines a 25 A rated current with a sensitive 30 mA rated residual operating current for dependable earth-leakage protection.
Its Type A residual-current characteristic enables detection of sinusoidal AC residual currents and pulsating DC residual currents, making the P1RD4P25A030 suitable for modern electrical installations containing compatible electronic equipment. The device is rated for 230/400 V AC at 50/60 Hz and has a 10 kA rated conditional short-circuit current when installed with the appropriate protective arrangement.
With a compact four-module, four-pole construction, 35 mm DIN rail mounting and IP20 frontal protection, the P1RD4P25A030 integrates efficiently into distribution boards and control panels where coordinated four-pole residual-current protection is required.

Reliable Four-Pole Type A Residual-Current Protection
The Lovato P1RD4P25A030 monitors the current balance between the conductors passing through the RCCB and disconnects the protected circuit when residual current reaches the device's operating threshold. Its 30 mA sensitivity makes it suitable for applications requiring sensitive residual-current protection as part of a correctly designed electrical installation.
The Type A characteristic provides detection of sinusoidal AC and pulsating DC residual currents, while the four-pole arrangement supports coordinated disconnection in compatible multi-pole systems. As an RCCB, the P1RD4P25A030 is specifically intended for residual-current protection; appropriate overcurrent protective devices should also be provided where overload and short-circuit protection are required.
Typical Applications
- Industrial and commercial electrical distribution boards.
- Three-phase electrical systems requiring four-pole residual-current protection.
- Circuits requiring 30 mA residual-current protection.
- Control panels and automation systems.
- Electrical installations containing compatible electronic loads.
