Product information

Description

The Hager CFC440J residual current circuit breaker is a 4-pole modular electrical protection device designed for installation in distribution boards. It features a 40A current rating and a 0.3A sensitivity of type AC, making it suitable for safeguarding electrical circuits against earth leakage faults in various environments.

Advantages

This residual current circuit breaker provides dependable protection against earth leakage currents, contributing to overall electrical safety in electrical installations. Its 4-pole configuration allows for multi-phase circuit protection, and the standard modular design ensures straightforward integration into existing distribution boards. Manufactured by Hager, it is built to meet established industry standards for quality and performance in residential and commercial electrical systems.

Suitable for

  • Residential electrical distribution boards
  • Commercial building sub-distribution panels
  • Protection of standard AC electrical loads against earth leakage
  • Multi-phase circuits requiring type AC residual current protection

When it may not be suitable

This device is not suitable for circuits that require protection against pulsating DC or high-frequency residual currents, as it is strictly a type AC circuit breaker. It should not be used in environments where direct current components are present in the electrical load.

Key specifications

  • 4-pole design
  • 40A current rating
  • 0.3A sensitivity
  • Type AC residual current protection

How to use

The device should be installed by a qualified electrician within a compatible distribution board or enclosure. It mounts onto a standard DIN rail. Connections to the incoming and outgoing power lines must be executed securely in accordance with local electrical wiring regulations and the manufacturer's connection guidelines. Regular manual testing via the integrated test button is recommended to verify correct mechanical and electrical operation.

What to consider before purchase

  • Verify that the 40A current rating and 4-pole configuration match the electrical load requirements of your circuit
  • Ensure type AC sensitivity meets the specific safety and regulatory standards for your application
  • Check available space in the distribution board for a modular 4-pole device
Usage recommendations: Perform a manual test of the residual current circuit breaker using the test button at least twice a year to ensure proper functional readiness. Installation and maintenance must always be carried out by a certified professional in compliance with applicable safety codes.

Single-phase electrical distributionKOOP Elektro FSS 2P 40A or Kanlux KRD10-2/25/300-ACTwo-pole configurations fit single-phase applications where three-phase switching is unnecessary.
The Hager CFC440J residual current circuit breaker 4-pole 40A 0.3A type AC is ideal for three-phase electrical installations requiring reliable 40A circuit protection with a 0.3A threshold for effective fire hazard prevention. Choose this model if you need a dependable four-pole Hager breaker for standard distribution board safety rather than a high-sensitivity device intended for direct touch protection.
