Circuit breakers, like the CELK1-1REC5-52-125.-A-01-T type, are designed to protect electrical systems from damages due to thermal, electrical and magnetic surge conditions. They provide a reliable protection and safety to the electrical system, by controlling the current in dangerous overload and short-circuit conditions. Moreover, they are fitted with a timer delay to allow temporary overcurrents, due to motor starting, without tripping (i.e. opening).

Application Field of the CELK1-1REC5-52-125.-A-01-T Circuit Breaker

The CELK1-1REC5-52-125.-A-01-T circuit breaker is mainly used in residential buildings. Its primary application, among other things, is residential service panels, handling up to 125 amp circuits. The maximum current rating for this breaker is 125 amps, and it is rated to handle up to 15kA Interrupting Rating at maximum voltage. This breaker can also be used in secondary switchboards and panel boards up to 600 VAC.

The CELK1-1REC5-52-125.-A-01-T circuit breaker is suitable for industrial applications as well. It is commonly used in motor control centers and switchgear, to provide protection and control for the incoming feeders, motors, and control circuits. This breaker is also used in distribution panel boards, as a primary form of protection.

Working Principle of the CELK1-1REC5-52-125.-A-01-T Circuit Breaker

The CELK1-1REC5-52-125.-A-01-T circuit breaker works on a thermal-magnetic principle. When an overload occurs, the magnetic system trips the circuit breaker at a predetermined current level. The thermal component of the system also works in a similar manner. If the overload reaches a certain level, the current heats up the heat element, which causes it to expand and trigger a trip mechanism, opening the circuit breaker and protecting the system against any further damages due to thermal overload.

The breaker also has a time delay feature, which prevents it from tripping even when a temporary overcurrent exists. This time delay is adjustable, and helps reduce nuisance trips during motor starting. The CELK1-1REC5-52-125.-A-01-T circuit breaker is also equipped with an undervoltage protection, which trips the breaker if the supply voltage drops below a predetermined level.

The CELK1-1REC5-52-125.-A-01-T circuit breaker is also equipped with a shunt trip, which can be triggered manually or remotely to open the breaker without waiting for its thermal or magnetic trip system. This feature can be used to isolate the system from power sources in emergency situations.

Conclusion

The CELK1-1REC5-52-125.-A-01-T circuit breaker is a reliable, safe and cost-effective solution for residential and industrial applications, providing effective protection against overcurrent, undervoltage or thermal overload. The adjustable time delay ensures that the circuit breaker will not trip during motor startups, while the shunt trip allows manual or remote tripping of the breaker in emergency situations.
