Why Choose the Lovato P1RD2P40A300 Residual Current Circuit Breaker?
The Lovato P1RD2P40A300 is a two-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 40 A rated current with a 300 mA rated residual operating current for earth-leakage protection.
Its Type A residual-current characteristic enables detection of sinusoidal AC residual currents and pulsating DC residual currents, making the P1RD2P40A300 suitable for electrical installations containing compatible electronic equipment. The device operates at 230 V AC and 50/60 Hz and has a 10 kA rated conditional short-circuit current when used with the appropriate protective arrangement.
With a compact two-module, two-pole construction, 35 mm DIN rail mounting and IP20 frontal protection, the P1RD2P40A300 integrates efficiently into distribution boards and control panels where dependable Type A residual-current protection is required.

Reliable Type A Residual-Current Protection
The Lovato P1RD2P40A300 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 300 mA residual-current rating makes it suitable for applications where this level of earth-leakage protection is specified as part of a correctly designed electrical installation.
The Type A characteristic provides detection of sinusoidal AC and pulsating DC residual currents, extending its suitability beyond basic Type AC applications. As an RCCB, the P1RD2P40A300 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.
- Control panels and automation systems.
- Circuits requiring 300 mA residual-current protection.
- Electrical installations containing compatible electronic loads.
- Machinery and OEM electrical panels.
- Commercial building electrical systems.
- Modular DIN rail distribution equipment.
