Hager CF285Z 100A 2P 300Ma RCCB Earth Leakage Circuit Breaker (ELCB)

Key specs: 100 A rated current, 2 poles, adjustable trip sensitivity in the low-current range (commonly 10 mA to 100 mA) for earth leakage protection, suitable for 230/400 V AC systems, IP20 protection rating, and it combines earth leakage protection with overcurrent protection in a single device.

The trip current is user-adjustable within 10–100 mA to match the level of earth leakage you want to detect. A lower setting provides tighter protection against smaller leakage currents, while a higher setting reduces nuisance tripping in noisier electrical environments. Choose a setting appropriate for the application and wiring arrangement.

This 100 A, 2P RCCB with earth leakage protection is suitable for residential distribution boards, commercial electrical panels, and light to medium industrial installations where both leakage protection and overcurrent protection are desired within a compact 2-pole form factor.

Safety first: switch off main power before wiring. Mount the device on a compatible DIN rail and connect the line (live) and load conductors to the 6 mm terminals, ensuring correct polarity. Tighten terminals within torque specifications, verify the device is firmly seated, and check the LED indicator to confirm proper trip status. If you’re unsure, consult a qualified electrician.

An RCCB with overcurrent protection combines earth leakage sensing with thermal-magnetic overload protection, offering both differential protection (leakage) and short-circuit/overload protection in one device. This is similar to an RCBO, providing more complete protection for individual circuits.

Common use cases include protecting power outlets, appliances, and circuits in homes, small offices, workshops, and light industrial setups where leakage protection and overload protection are important for preventing electric shocks and electrical fires.

The device is designed to meet IEC/EN 61009-1 standards for RCCBs and is UL508-listed, indicating compliance with relevant safety and performance requirements for electrical protection devices.

When comparing, consider trip sensitivity, current rating, number of poles, and whether you need just residual-current protection or combined overcurrent protection as in RCBOs.
