## Long description

The Hager CEC440J is a reliable 4-pole residual current circuit breaker designed to provide essential electrical safety and protection against earth leakage faults in modern electrical installations. Engineered to handle a 40A current rating with a 0.1A residual operating current of AC type, this device effectively safeguards residential and commercial circuits from potential hazards. By detecting insulation failures and stray currents, it helps prevent electrical shock and equipment damage, ensuring a stable and secure operational environment for your power distribution network.
Advantages
The Hager CEC440J residual current circuit breaker offers dependable performance for standard electrical setups. Its robust 4-pole construction allows for simultaneous disconnection of all phase and neutral conductors where applicable, ensuring comprehensive circuit isolation. Designed with precision, the device contributes to overall electrical system longevity by swiftly interrupting faulty currents before they escalate. The unit integrates seamlessly into standard distribution boards, making it a practical choice for professional installations requiring consistent earth leakage protection.
Suitable for
Residential electrical distribution boards and consumer units
Commercial building sub-panels and electrical systems
Protection against earth leakage and insulation faults
Safeguarding general electrical circuits and connected appliances
When it may not be suitable
This device is an AC type residual current circuit breaker, meaning it is not suitable for installations where DC components or pulsating direct currents may be present from electronic loads. For circuits involving complex variable speed drives, solar inverter systems, or specialized electronic equipment requiring Type A or Type B protection, alternative breaker types should be selected.
Key specifications

How to use
The Hager CEC440J must be installed exclusively by a qualified and certified electrician in accordance with local electrical regulations and wiring codes. The device is designed for DIN rail mounting inside a suitable enclosure or distribution board. Ensure that the power supply is completely disconnected before attempting any installation or wiring work. Connect the incoming and outgoing phase and neutral conductors to the corresponding terminals, ensuring secure screw tightening to prevent loose connections and potential overheating. Regular manual testing via the integrated test button should be performed periodically to verify proper mechanical and electrical operation.
What to consider before purchase
Verify that the 40A current rating matches the load requirements of your electrical circuit
Confirm that a 0.1A residual operating current aligns with your specific safety and selectivity needs
Ensure the installation environment is compatible with an AC type circuit breaker
Check available space on the DIN rail within your existing distribution board
For optimal safety and system reliability, always verify local electrical standards before installation, and ensure periodic testing of the circuit breaker is incorporated into your routine electrical maintenance schedule.
