Working Mechanism

  • Eaton CHQ Series thermal magnetic circuit breakers use a trip mechanism to sense the current flowing through them.
  • When the current exceeds the breaker's rated capacity, the trip mechanism triggers to open the circuit, interrupting the flow of electrical current and preventing further damage to the electrical system.
  • They can be manually reset to quickly restore power to the circuit.

Frequently Asked Questions

What are the electrical ratings of these Eaton CHQ Series thermal magnetic circuit breakers?

They have current ratings ranging from 15 to 60A and a voltage rating of 120 / 240VAC.

How much space do these circuit breakers need in a loadcenter?

The single-pole Eaton CHQ Series thermal magnetic circuit breakers require one 3/4-inch (19.1 mm) space, whereas 2-pole circuit breakers, with a common trip, need two 3/4-inch spaces.

What wire size is required for connecting to these Eaton CHQ Series thermal magnetic circuit breakers?

They can be connected to a #14 to 8 AWG or two #14 to 10 AWG sized copper / aluminium wires.
