Circuit Breakers

Circuit Breakers are vital components used in electrical systems to maintain the safe operation of the system. They are designed to make and break electrical connections automatically in the event of an overload or short circuit. Circuit Breakers are available in many different configurations, with IULHK111-1REC4-49-.200-01 being one of the most popular.

Application Field

The IULHK111-1REC4-49-.200-01 is designed for general purpose applications. It is capable of protecting circuits from overloads and short circuits, and is suitable for low voltage AC and DC circuits. Common applications include, but are not limited to, motor control circuits, lighting circuits, and any other applications where protection from overloads and short circuits is required.

Working Principle

IULHK111-1REC4-49-.200-01 circuit breakers use a thermal-magnetic trip unit to protect against overloads and short circuits. When the current flowing through the circuit breaker exceeds the rated value, the thermal element of the trip unit will heat up and open the contacts, breaking the circuit. Similarly, when the current rises to a dangerously high level, the magnetic element of the trip unit will be activated and the contacts will open, again breaking the circuit. Once either the thermal or magnetic element has been activated, the circuit breaker will need to be manually reset before it can be used again.

Advantages and Disadvantages

The IULHK111-1REC4-49-.200-01 has a number of advantages over other circuit breakers. It is reliable and easy to install, and is capable of quickly responding to high levels of current. However, it also has a few drawbacks. It can only protect against overloads and short-circuits, so if other types of problems are encountered, another device will be required to provide protection.

Conclusion

The IULHK111-1REC4-49-.200-01 is a reliable and cost-effective circuit breaker that is suitable for a wide range of applications. It is easy to install and has a fast response time, making it an ideal choice for protecting circuits from overloads and short-circuits.
