Circuit Breakers

A circuit breaker is an electrical switch device capable of interrupting an electric circuit to prevent overloading of current. The IUGZXF66-33233-45 is one such device with a specialized switching mechanism designed for higher level of protection.

Application Field

The IUGZXF66-33233-45 circuit breaker is typically used in installation and control systems operating at voltage of 600V or below. It is mainly used to protect starters and smaller loads, serving as equipment protection in low-voltage power supply systems.

Working Principle

When the circuit breaker is opened, current no longer flows through an energized circuit. This can be achieved by electromechanical, electronic or vacuum switching techniques.

The IUGZXF66-33233-45 employs a thermal tripping system to detect current overload. An internal thermal sensor captures excessive temperature generated from overloading current and initiates a tripping action. This prevents further current from flowing, hence protecting the circuit from damage.

The IUGZXF66-33233-45 also uses a magnetic tripping system to react to short circuits. When a short circuit occurs, an internal coil becomes highly magnetized which generates a signal which trips the circuit breaker.

The IUGZXF66-33233-45 also has a multiple rating system; it allows manual operation as well as automatic cycling and reclose. This means that the circuit breaker may be reset manually or automatically depending on the particular application.

Finally, the IUGZXF66-33233-45 also has a locking mechanism to ensure that the circuit breaker stays in the open position before reset is attempted.
