Circuit Breakers

Circuit breakers are devices that switch to open a circuit whenever the current exceeds a set limit. They are able to sense overloads in electrical circuits, protect circuits from large currents and prevent the sparking and arcing of electrical contacts. They also protect circuits and their components from damage due to shorts or other faults. The CMLHPK111-38646-250-V circuit breaker is a miniature circuit breaker that offers short circuit protection up to a nominal current of 250 A.

Application Field

The CMLHPK111-38646-250-V is designed for use in a wide variety of applications. It is suitable for installation in residential, commercial and industrial electrical systems. It is also suitable for installations requiring manual operation, thermal protection, short-circuit protection, and overcurrent protection. In addition to its range of circuit breakers, the CMLHPK111-38646-250-V also offers a manual reset switch, which allows the circuit to be manually tripped, even when the breaker has not been tripped due to excessive current.

Working Principle

The CMLHPK111-38646-250-V works by using an electromagnet to break the circuit when a fault is detected. This is accomplished by the current flowing through the coils of the electromagnet creating a force which overcomes a set spring tension and allows the contacts to open. This opens the circuit and shuts off the power to the circuit. When the fault is cleared, the spring tension is reapplied and the contacts are restored. The reset switch can be used to manually trip the breaker, allowing the circuit to be safely de-energized, even when there is no fault.

The CMLHPK111-38646-250-V is designed to provide reliable overcurrent protection and is capable of withstanding high levels of shock and vibration. It is also designed to withstand the harsh conditions of the marine environment. The circuit breaker is UL-rated and conforms to NationalFire Protection Association (NFPA) standards.

Conclusion

The CMLHPK111-38646-250-V is a reliable and efficient miniature circuit breaker designed for a wide variety of applications. It offers short circuit protection up to a nominal current of 250A, manual reset switch, thermal protection, short-circuit protection, and overcurrent protection. The circuit breaker is also designed to withstand the harsh conditions of the marine environment, making it an ideal choice for any environment.
