Circuit breakers are important devices that are found in a wide variety of applications. The R41-1REF..S00381438 circuit breaker is one such device, and it has a wide range of uses. Let\'s take a look at the application field and working principle of the R41-1REF..S00381438.

Application Field of R41-1REF..S00381438 Circuit Breakers

The R41-1REF..S00381438 circuit breaker is a three-phase manual circuit breaker. It is designed for use in industrial and commercial applications, as well as for residential applications. The breaker is designed for use in AC three-phase systems with a system voltage of 220-480VAC and a rated short-circuit current of up to 10,000A. It is rated for use at temperatures of -5°C to +45°C.

This breaker can be used as an automatic overcurrent protection device, as well as a manual interrupter to manually disconnect power from the system in case of an emergency. It is also widely used in combination with MCB and MCCB devices, as it provides a short-circuit current rating comparable to low-voltage ones.

Working Principle of R41-1REF..S00381438 Circuit Breakers

The R41-1REF..S00381438 circuit breaker is based on a thermal-magnetic operating principle. Its main components are the main contact, which carries the current, the temperature-sensitive element which senses the temperature rise due to the current flowing through the element by way of the bimetallic strips, and the tripping mechanism which releases the latch that holds the main contact in place. The tripping mechanism is activated by either the thermal element or the magnetic element.

The thermal element is activated when the current flowing through it heats up a bimetallic strip beyond its melting point. As the strip starts to bend, it activates the tripping mechanism which releases the latch and disconnects the main contact. On the other hand, the magnetic element is activated when the current reaches a certain predetermined level, which causes an electromagnet to become magnetized sufficiently to release the latch and disconnect the main contact.

The R41-1REF..S00381438 circuit breaker is designed to be flexible and easy to use, making it suitable for a wide range of applications. The breaker can be used as a manual interrupter or as an automatic overcurrent protection device. It is also compatible with MCB and MCCB devices, providing a short-circuit current rating comparable to low-voltage ones.
