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.
