P1RD2P25AC300 Lovato RES.CURRENT DEV.2P 25A IDN 300MA TYPE AC

Why Choose the Lovato P1RD2P25AC300 Residual Current Circuit Breaker?

The Lovato P1RD2P25AC300 is a 2-pole residual current circuit breaker (RCCB) designed to provide reliable earth leakage and 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 residual current protection.

Rated at 25 A with a rated residual operating current of 300 mA, the P1RD2P25AC300 is designed to detect Type AC residual currents. Its Type AC residual operating characteristic responds to sinusoidal alternating residual currents, making it suitable for appropriately specified circuits where protection against earth leakage and associated fault risks is required.

The P1RD2P25AC300 operates at 230 V AC and 50/60 Hz, with a 10 kA conditional short-circuit current rating. 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 Residual Current Protection for Electrical Systems

Residual current circuit breakers such as the Lovato P1RD2P25AC300 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 leakage currents.

The Type AC characteristic is designed to detect sinusoidal alternating residual currents. With its 300 mA sensitivity, 25 A current rating and two-pole configuration, the P1RD2P25AC300 is suited to appropriately designed installations requiring residual current protection at this threshold. 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 installations with sinusoidal AC residual current characteristics.
• Earth leakage protection for machinery and equipment circuits.
• OEM electrical cabinets and industrial distribution systems.
