Features

  • Their three-pole design provides an interrupting rating of 65kA at 600VAC and the compact design minimises panel sizing.
  • These MCCBs feature a 310+ electronic trip mechanism allowing long-time, short-time and instantaneous trip functionalities for current limiting protection.
  • They include a high load alarm to indicate the open status of circuit breakers in the electrical circuit.
  • They feature bolt-on mounting for ease of installation and maximum protection against vibrations.
  • The moulded case holds current carrying components, trip devices and mechanisms integrated into a compact space.

Standards and Approvals

  • UL

Frequently Asked Questions

What is the purpose of a three-pole circuit breaker?

Three-pole circuit breakers are designed to connect three different conductors for use in heavy-duty industrial motors. If a surge happens in any of the conductors, the breaker trips and the circuit opens to prevent fire hazards.

How to reset a tripped circuit breaker?

When the breaker trips, it can be reset again by pressing the OFF and then the ON pushbutton to close the breaker contacts and start the current flow.

What is a circuit breaker?

Eaton circuit breakers are designed to close the circuit by tripping mechanism when an overload condition occurs. Unlike fusible switches, these breakers can be manually reset by a toggle.
