Circuit Breakers

Circuit breakers, such as IULK211-38479-100, are safety devices that protect electrical circuits from damage caused by overload and short circuit. They are classified into two categories: thermal and magnetic.

Theory of Operation

The main purpose of a circuit breaker is to protect components and circuits from current overload. The circuit breaker, when configured correctly for the application, ensures overcurrent protection, that is, it will open when the maximum current through the breaker is exceeded or a short circuit event occurs.

IULK211-38479-100 is a thermal-magnetic circuit breaker that works by sensing both current and temperature variations. This type of breaker consists of two components: a thermal element and a magnetic element. The thermal element works by sensing a sudden rise in temperature due to an overload in the circuit and will trip after a predetermined time. The magnetic element works by sensing the sudden increase in current flow and trips instantly if the short-circuit current rises above the rated value. Depending on the rating of the breaker, it can be used in both home and industrial applications.

Application of IULK211-38479-100

IULK211-38479-100 is suitable for use in residential, industrial, and commercial applications as a circuit breaker. It is used commonly in distribution systems, lighting circuits, air conditioning equipment, and motor protection. In the industrial sector, it can be used for the protection of motors, bus ducts, etc.

This thermal-magnetic circuit breaker has a short-circuit capacity of up to 100kA and is suitable for installation in panels, housing, transformers, motor control centers, and machine tools. It features a wide range of configurations and switching times, making it suitable for many applications.

Benefits

Using IULK211-38479-100 as a circuit breaker has a number of benefits. It is capable of withstanding high inrush currents that can occur during starting of an electric motor and can provide overload protection for a wide range of devices. It also provides an economical solution for overcurrent protection with its short-circuit current ratings up to 100 kA and short switching times.

Overall, IULK211-38479-100 is a reliable and easy-to-use thermal-magnetic circuit breaker that provides reliable protection for residential, industrial, and commercial applications.
