Residual Current Circuit Breaker (RCCB) E.NEXT EX-P003004 2P 25A 30mA

The E.NEXT EX-P003004 Residual Current Circuit Breaker (RCCB) is a 2-pole protective device rated for 25 A with 30 mA residual current sensitivity. Designed to detect imbalance between live and neutral conductors, it disconnects supply when earth leakage exceeds the set threshold, reducing the risk of electric shock and limiting fire hazard caused by insulation faults. This compact RCCB is intended for installation in residential and light commercial distribution boards where basic residual-current protection is required for circuits and connected appliances.

Advantages

The device offers prompt disconnection at 30 mA sensitivity, ensuring rapid response to dangerous leakage currents. Its 2-pole format enables use on single-phase circuits, providing protection for both live and neutral conductors. Built for standard DIN-rail mounting, the RCCB integrates into common distribution boards and is compatible with typical household and small business electrical installations. The straightforward design simplifies wiring and maintenance while delivering essential residual-current protection.

Suitable for

• Residential distribution boards and apartment circuits
• Light commercial installations such as offices and small shops
• Protection of circuits supplying kitchen appliances, bathroom circuits, and portable tools
• Supplementary protection where earth-fault detection is required

Key specifications

• Poles: 2-pole (live and neutral)
• Rated current: 25 A
• Residual operating current: 30 mA
• Tripping characteristic: residual-current operated (AC or type A depending on model design)
• Mounting: DIN-rail compatible enclosure for standard distribution boards
• Application: single-phase circuit protection against earth leakage

How to use

Install the RCCB in the distribution board according to national wiring regulations and the installer’s instructions. Connect the incoming supply conductors to the top terminals and the outgoing load conductors to the bottom terminals, ensuring tight and secure connections. Verify correct polarity for live and neutral conductors before energizing. After installation, test the device using its test button (if provided) or a suitable testing device to confirm proper tripping at the specified sensitivity. Observe local electrical codes for coordination with downstream overcurrent protection devices.

Usage recommendations

Regularly test the RCCB at least every three months using the built-in test function or a qualified tester to ensure reliable operation. Avoid installing the device in excessively wet, corrosive, or high-dust environments unless the distribution board provides appropriate protection. For circuits with electronic loads or medical equipment, verify compatibility with the RCCB tripping characteristic and consult a qualified electrician for selective protection schemes.
