£247.13
The Lovato P1RD4P40A300 is a dependable residual current device (RCD) designed to provide earth leakage protection in commercial, industrial and low-voltage electrical installations. Part of the Lovato P1RD residual current device series, it combines reliable fault detection with a compact modular design suitable for modern electrical distribution systems.
This four-pole residual current device monitors electrical circuits for leakage currents and disconnects the supply when a fault condition is detected. Its modular construction allows straightforward installation alongside other protective devices, providing an efficient solution for improving electrical safety in three-phase systems.
With a rated current of 40 A, a residual operating current of 300 mA and Type A sensitivity, the P1RD4P40A300 is suitable for applications requiring protection against alternating and pulsating direct residual currents in three-phase electrical installations.
Residual current devices such as the Lovato P1RD4P40A300 continuously monitor electrical circuits for leakage currents caused by insulation faults or unwanted current paths. When excessive residual current is detected, the device disconnects the circuit to help improve electrical protection.
The Lovato P1RD series provides installers and panel builders with compact and dependable protection solutions for distribution boards, control cabinets and industrial electrical systems where reliable residual current monitoring is required.
