Working Mechanism

  • These circuit breakers incorporate both fixed thermal and magnetic trips.

    • Fixed Thermal Trips

    • Fixed thermal trips are based on the heat generated by the current passing through the circuit.
    • The trip unit contains a bimetallic strip sensitive to temperature changes.
    • As the current increases, the bimetallic strip heats up and bends, triggering the breaker to trip.

    Fixed Magnetic Trips

    • Fixed magnetic trips use the strength of the magnetic field created by the current passing through the circuit.
    • The trip unit contains an electromagnet sensitive to changes in magnetic field strength.
    • As the current increases, the magnetic field strength increases and when it reaches a certain level, it triggers the breaker to trip.

Standards and Approvals

  • UL
  • CSA

Frequently Asked Questions

How to maintain these Eaton HCA circuit breakers?

Their maintenance involves inspection and testing of the circuit breaker, as well as replacement of any worn or damaged components.

What is the difference between HCA and HMC circuit breakers?

Eaton HCA (High Current Application) circuit breakers are designed for higher current ratings and interrupting capacities, while HMC (High Magnetic Capacity) circuit breakers are for higher levels of short-circuit magnetic forces.

How to choose the right Eaton HCA circuit breaker for my application?

The right selection depends on the voltage level, the current rating and the specific protection features required.

Can I install these Eaton HCA circuit breakers to new trip units?

Yes, users can retrofit these circuit breakers with new trip units to upgrade their protection features or adjust trip settings for a specific application.
