Question 1

What is the Hager CF285Z 100A 2P 300mA RCCB ELCB and what does it protect?

Accepted Answer

The Hager CF285Z is a 2-pole RCCB (residual current circuit breaker) with earth leakage protection and overcurrent protection. It helps guard against electric shock and fire by disconnecting the circuit when it detects an imbalance between live and neutral (earth leakage) and also provides overcurrent protection for the connected circuit.

Question 2

What are the key specifications of this RCCB (current rating, trip sensitivity, voltage, and protection type)?

Accepted Answer

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.

Question 3

How does the adjustable trip current work and why is the 10 mA–100 mA range important?

Accepted Answer

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.

Question 4

What applications is this RCCB best suited for (use cases in residential, commercial, or industrial settings)?

Accepted Answer

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.

Question 5

How do I install the Hager CF285Z safely and correctly?

Accepted Answer

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.

Question 6

What makes an RCCB with overcurrent protection different from a standard RCCB?

Accepted Answer

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.

Question 7

What are common use cases for this product in terms of safety and protection?

Accepted Answer

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.

Question 8

What safety and compliance standards does this RCCB meet?

Accepted Answer

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.

Question 9

How does this model compare with other RCCB/RCBO options available on Fepy.com?

Accepted Answer

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. For similar options on Fepy.com, you can explore RCCB/RCBO listings via the site’s search results to see comparable models and their specifications: https://fepy.com/search?q=RCCB and https://fepy.com/search?q=RCBO

Question 10

What wiring and terminal details should I know before buying or installing?

Accepted Answer

This RCCB uses 6 mm terminals and is intended for use in wiring systems up to 230/400 V AC. It is designed for a class 2 wiring arrangement and features an easy-to-see LED indicator for trip status, aiding quick fault identification during installation and testing.

Question 11

What should I do if I need to return or exchange this item?

Accepted Answer

If you need to return or exchange the item, refer to the seller-specific return terms on Fepy. Returns are typically considered under the retailer’s policy, and you’ll usually need to follow the stated return window and conditions as listed in the product listing or seller terms.
