P1RD2P63A300 Lovato RES.CURRENT DEV.2P 63A IDN 300MA TYPE A

Why Choose the Lovato P1RD2P63A300 Residual Current Circuit Breaker?

The Lovato P1RD2P63A300 is a 2-pole residual current circuit breaker (RCCB) designed to provide reliable residual current protection in electrical installations. As part of the Lovato P1RD series, it combines a compact two-module format with IEC compliance, making it suitable for distribution boards, industrial control panels and electrical systems requiring dependable earth leakage protection.

Rated at 63 A with a rated residual operating current of 300 mA, the P1RD2P63A300 uses a Type A residual operating characteristic. This enables detection of sinusoidal alternating residual currents and pulsating DC residual currents, making Type A protection particularly useful for circuits containing electronic equipment capable of producing pulsating residual current waveforms.

The P1RD2P63A300 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 straightforward integration into electrical distribution equipment, machinery and control cabinets.

Reliable Type A Residual Current Protection

Residual current circuit breakers such as the Lovato P1RD2P63A300 monitor the balance of current flowing through the conductors of an electrical circuit and disconnect the supply when residual current exceeds the specified threshold. This provides an important protective measure against earth leakage faults and helps reduce risks associated with insulation failure and unintended leakage currents.

The Type A characteristic provides protection for sinusoidal alternating residual currents as well as pulsating DC residual currents that may be generated by electronic equipment. With its 300 mA sensitivity, 63 A current rating and two-pole configuration, the P1RD2P63A300 is suited to appropriately designed installations requiring Type A residual current protection. As an RCCB, it should be coordinated with suitable overcurrent and short-circuit protection according to the requirements of the installation.

Typical Applications

• Single-phase electrical distribution boards.
• Industrial and commercial control panels.
• Circuits requiring 300 mA residual current protection.
• Electrical circuits supplying suitable electronic equipment.
