Circuit Breakers

Circuit breakers are components of an electrical system that are designed to protect power circuitry from short circuits, overloads, and other electrical faults. The 3120-F311-P7T1-W14FR3-5A circuit breaker is a single-pole, two-pole, and three-pole AC output circuit breaker with a 3,000 amp current rating. It is available in panel mount and surface mount versions, and has UL489 listing, CSA certification, CE approval, and Type 2 coordination.

Application Field

The 3120-F311-P7T1-W14FR3-5A circuit breaker is suitable for both residential and commercial applications. It can be used in motor protection applications, as well as surge protection applications, in single-pole, two-pole, and three-pole configurations. It is a suitable choice for high-power applications, such as larger HVAC systems, industrial plants and equipment, and other large power-consuming operations.

Working Principle

The 3120-F311-P7T1-W14FR3-5A circuit breaker operates via an overcurrent detection system. It is designed to detect when a circuit is overloaded, short-circuited, or is otherwise drawing too much current. When an overload or short circuit is detected, the breaker will trip the circuit, cutting off the power and protecting the wiring and other components from damage. After the fault has been corrected, the circuit breaker can be reset manually, allowing power to be restored to the circuit.

The 3120-F311-P7T1-W14FR3-5A circuit breaker is designed to also provide protection against surge currents. If a sudden, large impulse current is detected, the breaker will trip, preventing the potentially damaging current from reaching other components. It is important to note that surge protection provided by a circuit breaker is limited, and that more appropriate surge protection solutions should be employed if surge protection is critical.

Conclusion

The 3120-F311-P7T1-W14FR3-5A circuit breaker is a robust, UL489 listed, AC output circuit breaker designed for use in residential and commercial applications. It is capable of providing overload and short circuit protection, as well as surge protection, to ensure the safety of wiring, components, and personnel.
