The Lovato P1RD4P40AC030 is a 4-pole residual current circuit breaker (RCCB) designed to provide reliable residual current protection in three-phase electrical installations. As part of the Lovato P1RD series, it combines a compact four-module format with IEC compliance, making it suitable for industrial and commercial distribution boards, control panels and electrical systems requiring dependable earth leakage protection.
Rated at 40 A with a rated residual operating current of 30 mA, the P1RD4P40AC030 uses a Type AC residual operating characteristic. It is designed to detect sinusoidal alternating residual currents, while its 30 mA sensitivity makes it suitable for appropriately designed installations requiring additional protection against electric shock.
The P1RD4P40AC030 has a rated operational voltage of 230/400 V AC at 50/60 Hz, together with a 10 kA rated conditional short-circuit current. Its four-pole, four-module construction mounts directly onto a standard 35 mm DIN rail, providing straightforward integration into three-phase electrical distribution equipment and control cabinets.
Residual current circuit breakers such as the Lovato P1RD4P40AC030 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, when correctly selected and installed, can contribute to protection against electric shock.
The Type AC characteristic is designed for sinusoidal alternating residual currents. Combined with its 30 mA sensitivity, 40 A current rating and four-pole configuration, the P1RD4P40AC030 provides a practical residual current protection solution for appropriately designed three-phase AC installations. As an RCCB, it should be coordinated with suitable overcurrent and short-circuit protection according to the requirements of the installation.
