Fusebox RTA1001002S Description
The FuseBox RTA1001002S 2 module Type A 100A 100mA double pole Time Dealyed Residual Current Device (RCD) is typically used as a main incomer to a consumer unit or as a sub-main RCD in commercial or industrial settings. Offers essential protection against earth leakage faults for applications where additional fault protection is required.
100A current rating, suitable for use as a main switch and a point of isolation for consumer units in both domestic and light commercial applications.
100mA trip sensitivity is designed to provide fire protection and to prevent risk to equipment.
The time-delay function allows it to differentiate between downstream faults, meaning faster-acting RCD or RCBO on the individual circuit to trip first. This prevents the entire board from losing power in the event of a single fault.
Type A RCD provides protection against AC fault currents and pulsating DC fault currents.
Double-pole isolation ensuring both the live and neutral conductors are disconnected simultaneously when a fault is detected, providing a complete and safe isolation.
2 module width (36mm) allows it to be neatly integrated into a standard consumer unit, saving valuable space.
Designed for quick and secure mounting on a standard 35mm DIN rail, ensuring a hassle-free and professional installation.
Compliant with BS EN 61008-1.
