4435.0103 Circuit Protection

Circuit Breakers

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow. Generally thermal-magnetic circuit breakers are the prevalent type of circuit breaker found in most electrical distribution systems today.

4435.0103 Application Field & Working Principle

The 4435.0103 is a thermomagnetic circuit breaker used in AC and DC low voltage applications. It is an ideal solution for over current protection with its advanced initiation and response systems. It provides short circuit protection and overload current protection along with overload temperature protection.

The breaker\'s thermal system is based on a thermal element, made of a bimetal strip which is temperature sensitive. In a overload condition current flows through elements, which increase the temperature of the bimetal strip until the strip deflects to open or trip the breaker. The breaker also has a magnetic trip system which is activated in the event of a short circuit situation. The magnetic trip element operates by sensing the current and generating a magnetic field which then trips the breaker.

The 4435.0103 is designed to be applied to single and parallel circuits, such as general short-circuit protection for large single operations, illumination and electric heating. It uses integrated intelligent protection technology to detect current and temperature state of the circuit, enabling very fast detection and protection operations.

This circuit breaker provides a wide range of settings and covers a range of current ratings. The installer can set the trip curve, short circuit and overload current levels, circuit temperature, auxiliary contacts and other parameters of the breaker depending on the application.

The 4435.0103 circuit breaker can be installed in various applications, such as residential, industrial and commercial settings. It can be used on panel boards, switchboards, transfer switches, motor control centers, control panels, disconnects and many other electrical installations. Its short circuit protection, overload protection and temperature protection features make it an ideal choice for ensuring safety in various applications.
