Working Mechanism

  • These GHB Series moulded case circuit breakers incorporate both fixed thermal and magnetic trips.

    • Fixed Thermal Trips:

    • Fixed thermal trips are based on the heat produced by the circuit's current flow.
    • The trip unit contains a bimetallic strip sensitive to temperature changes.
    • The bimetallic strip heats up and bends as the current rises, tripping the breaker.

    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.
    • When the magnetic field intensity reaches a certain threshold, it causes the breaker to trip as the current increases.

Standards and Approvals

  • UL
  • CSA
  • IEC

Frequently Asked Questions

How to install these circuit breakers?

  • Switch off the main power disconnect.
  • Remove front panel front trim.
  • Position circuit breaker line-end conductor retaining screw from bus bar.
  • Place circuit breaker load-end retaining recess under hook mounting rail.
  • Secure line-end conductor to bus bar with screws.
  • Connect load terminals and accessories after mounting the circuit breaker.
  • After completion of the installation process, check the terminal connecting hardware for correct torque readings.
  • Install the panelboard front trim back.

How to inspect these MCCBs on-field?

  • Use a lint-free dry cloth or brush to remove dust or dirt. If you find any difficult-to-remove contamination, find the source and eliminate the problem.
  • Switch the circuit breaker on and off several times to ensure free movement of mechanical linkages.

How to choose the right GHB Series circuit breaker for my application?
