Hager ADM425C RCBO Residual Current Circuit Breaker with Overcurrent Protection 3+N 25A 30mA Type A 6kA

The Hager ADM425C is a professional-grade RCBO (Residual Current Circuit Breaker with Overcurrent Protection) engineered to provide comprehensive electrical safety in modern installations. This 3+N pole device integrates both residual current protection and overcurrent protection into a single compact unit, ensuring efficient space utilization in distribution boards while maintaining high performance standards for 230-400V AC electrical systems.

Advantages

This device offers a robust solution for circuit protection by combining two essential safety functions into one component, which simplifies installation and reduces the amount of wiring required within the consumer unit. Its Type A sensitivity ensures reliable detection of both alternating and pulsating direct current residual currents, providing a higher level of protection compared to standard AC types. The 6kA breaking capacity is sufficient for most residential and light commercial applications, ensuring the device can safely interrupt fault currents to prevent damage to wiring and connected equipment.

Suitable for

• Residential electrical distribution boards
• Commercial office lighting and power circuits
• Protection of sensitive electronic equipment
• Systems requiring both short-circuit and earth leakage protection

This device may not be suitable for industrial environments with very high prospective short-circuit currents exceeding 6kA. It is also not intended for use in DC-only electrical systems or specialized high-frequency installations where specific protection characteristics are required beyond the Type A standard.

Key specifications

• Configuration: 3+N poles
• Rated current: 25A
• Residual current sensitivity: 30mA
• Protection type: Type A
• Breaking capacity: 6kA
• Operating voltage: 230-400V AC

Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is designed for mounting on a standard DIN rail within an appropriate enclosure. Ensure that the supply cables are correctly sized for the 25A rating and that all terminal connections are tightened to the manufacturer's specified torque to prevent overheating.

What to consider before purchase

• Verify that the 25A rating matches the load requirements of your circuit
• Ensure the 3+N configuration is compatible with your existing distribution board layout
• Confirm that the 6kA breaking capacity meets the safety requirements of your specific electrical installation
• Check that the 30mA sensitivity is appropriate for the intended level of personnel or equipment protection

Usage recommendations: Regularly test the device using the integrated test button to ensure the mechanical tripping mechanism remains functional. It is recommended to perform this test at least every six months to maintain optimal safety standards.
