Working Mechanism

  • These EGSDC Series DC 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.

Features

  • Eaton EGSDC Series DC circuit breakers have a contact design that pushes away contact arms for protection during false currents.
  • They have thermal-magnetic trip units for protection against overloads and short circuits.
  • These circuit breakers feature a three-pole configuration to protect all three phases in 3-phase electrical systems.

Standards and Approvals

  • UL

Frequently Asked Questions

What is the difference between a circuit breaker and a fuse?

A circuit breaker can be reset and reused, while a fuse must be replaced once it has blown.

How to choose the right circuit breaker for a specific application?

Choosing the right circuit breaker for a specific application depends on the electrical load requirements of the circuit, the voltage & frequency of the electrical supply and the environment in which the circuit breaker will be used.

How to maintain these Eaton EGSDC Series DC circuit breakers?

  • Inspect them for damage or wear.
  • Test their tripping function.
  • Check the tightness of electrical connections.
