Residual-current circuit breaker (RCD) 2P 25A 30mA Type AC EATON xPole Home HNC-25/2/003 (MPN 194690)

EATON xPole Home HNC-25/2/003 is a 2-pole residual-current circuit breaker (RCD) with a rated current of 25 A and residual sensitivity of 30 mA, Type AC. Designed to detect alternating current leakage to earth, this device interrupts the supply when leakage exceeds the set threshold, helping to reduce the risk of electric shock and fire. The unit is intended for installation on standard DIN rails in residential and light commercial distribution boards and complements overcurrent protection devices to provide comprehensive circuit safety and compliance with electrical regulations.

Advantages

The RCD provides selective disconnection of faulty circuits by sensing AC leakage currents and operating at 30 mA sensitivity, which is commonly required for personal protection. Its 2-pole configuration allows simultaneous disconnection of both live and neutral conductors, improving safety in single-phase installations. The compact design is suitable for standard distribution panels and the device is compatible with DIN-rail mounting, simplifying installation and replacement in domestic and small commercial switchboards.

Suitable for

• Single-phase residential electrical circuits where protection against earth leakage is required
• Light commercial and office distribution boards
• Protection of socket outlets, lighting circuits and small appliances
• Installation in DIN-rail consumer units and sub-distribution boards

Key specifications

• Poles: 2-pole residual-current device
• Rated current: 25 A
• Residual current (sensitivity): 30 mA
• Tripping characteristic: Type AC (senses alternating leakage currents)
• Mounting: DIN-rail compatible
• Application: single-phase circuits and neutral switching

How to use

Install the RCD in the distribution board on a standard DIN rail, ensuring the incoming supply is connected to the designated line and neutral terminals and that the load circuits are connected to the outgoing terminals. Switch off the supply before wiring and follow local electrical codes and safety procedures. After installation, test the device using its built-in test button or with appropriate test equipment to verify correct operation and trip at the specified residual current sensitivity. Periodic testing and inspection are recommended to ensure continued protection.

Usage recommendations

Use this Type AC RCD where detection of sinusoidal AC earth leakage is sufficient. For circuits with devices that produce residual direct or pulsating DC components (for example, certain electronic chargers or inverters), consider a device with a Type A or Type B characteristic. Ensure compatibility with upstream overcurrent protection and maintain routine testing according to local regulations.
