This Mehr 25 A RCD Circuit Breaker is designed for professionals and general maintenance tasks requiring reliable AC Type electrical protection. Its key benefit is safeguarding circuits against earth faults with a 30mA sensitivity. A potential caveat is its specific AC Type application, requiring users to confirm compatibility with their system. This 4-pole device is compliant with EN61008-1 standards, offering a robust solution for electrical safety.

An RCD (Residual Current Device) circuit breaker is designed to protect people from electric shock by rapidly disconnecting the power supply when it detects an imbalance in the current flowing through the live and neutral conductors, indicating a fault to earth.
No, this RCD circuit breaker is designed for AC (Alternating Current) Type applications only and is not suitable for DC (Direct Current) circuits.
A 30mA sensitivity means the RCD will trip and disconnect the power when it detects a fault current as low as 30 milliamperes flowing to earth. This level is generally considered safe for preventing serious electric shock.
It is recommended to test RCDs regularly, typically monthly, using the built-in test button if available. Always follow manufacturer guidelines and local electrical regulations for testing frequency.
Installation of RCDs should only be performed by a qualified and certified electrician to ensure safety and compliance with electrical standards.
A 2-pole RCD typically protects a single-phase circuit by switching live and neutral. A 4-pole RCD is designed for three-phase circuits, switching all three live conductors and the neutral, providing protection across all phases.
Our shop offers a wide selection of electrical consumables, including various RCD circuit breakers with different specifications to suit diverse industrial and commercial needs. Please browse our catalog for other Mehr models like the 40A (ERCD443) and 63A (ERCD463) variants.
Check for overloaded circuits or incompatible appliances. Ensure the load does not exceed the 25A rating. A persistent issue may indicate a fault requiring professional inspection.
Verify power supply to the RCD. If power is confirmed, the RCD may be faulty and requires replacement by a qualified electrician.
Do not attempt to use a damaged RCD. Immediately disconnect power to the circuit and replace the unit with a new, certified device.
Setup: Installation of the ERCD425 should be performed by a qualified electrician. It requires proper integration into an existing electrical distribution board or control panel, ensuring all connections are secure and compliant with local electrical codes. Ensure the device is correctly rated for the circuit it is protecting.
Compatibility: This RCD is designed for AC Type applications. It is compatible with standard electrical systems that operate on alternating current and adhere to EN61008-1 standards. Verify that the circuit's expected load does not exceed the 25A rating.
Care: As an electrical safety device, the ERCD425 requires minimal user care. Regularly test its functionality using the built-in test button (if applicable, consult device specifics) as per manufacturer recommendations or local regulations. Keep the area around the device clean and free from dust or moisture. Avoid any unauthorized modifications.
