How to use

The Hager HET041NR should be installed by a qualified electrician in accordance with local electrical codes and safety regulations. It is designed for mounting within a compatible distribution board or enclosure. Once installed, the device can be manually operated using the front-facing toggle to connect or disconnect the circuit. Regular inspections should be performed to ensure that all terminal connections remain secure and that the device is free from dust or debris that could impede its operation.

What to consider before purchase

• Verify that the 40A current rating matches your specific circuit requirements.
• Ensure the 70kA breaking capacity is appropriate for the prospective fault current levels of your installation.
• Confirm compatibility with your existing distribution board or panel layout.
• Check that the 3-pole configuration aligns with your electrical system architecture.

Usage recommendations

Always ensure that the power supply is completely disconnected before attempting any installation or maintenance work on the circuit breaker. Periodically test the device functionality to maintain optimal safety standards within your electrical system.
