EATON CHND Series Electronic Molded Case Circuit Breakers, NG Frame
Eaton CHND-Series moulded case circuit breakers are useful in the manufacturing, construction and automobile industries. These NG-frame units detect overloading and interrupt the supply to save equipment from short circuits.
AWorking Mechanism
- Circuit breakers get triggered when faulty current flows through the system.
- The trip coil of the breaker gets energised and moves away from each other, thus opening the circuit.
Features
- Eaton CHND-Series moulded case circuit breakers have an interrupt rating of 65kAIC at 480V.
- They have LS / LSIG / LSIA trips to interrupt the supply during overloads.
- These three-pole units are equipped with Digitrip OPTIM 550 for true RMS current sensing.
Standards and Approvals
- HACR
- UL
Frequently Asked Questions
How are circuit breakers better than fuses?
Circuit breakers can be easily reset after they trip due to a fault, making them reusable units. Fuses, on the other hand, break once they detect overload and cannot be used more than once.
Can humidity trip a breaker?
When moisture corrodes wiring and other electrical contacts, short-circuit occurs. Humidity causes a current increase in the circuit, which trips the circuit breaker.
How is a circuit breaker different from a switch?
A switch opens and closes the circuit in normal operation, while a circuit breaker opens or closes the circuit during faulty currents.
