Circuit Breakers: 9129633200 Application Field and Working Principle

Circuit breakers are an important part of an electrical system. They are designed to protect electrical circuits and equipment from damage caused by overloads, ground faults, and other problems. The 9129633200 circuit breaker is a mid-range circuit breaker designed to protect medium voltage applications. It offers increased accuracy, improved power ratings, and a three-pole design.

Applications

The 9129633200 circuit breaker can be used in a number of applications, including overhead lines, substation wiring, and distribution systems. It is suitable for applications where space is at a premium, due to its slim design. The compact design also allows for quick installation and maintenance. It is especially suitable for medium voltage applications with high fault detection accuracy.

Design and Features

The 9129633200 circuit breaker has a three-pole design with built-in trip units. The trip units offer accuracy of up to 0.2% overcurrent detection, allowing the circuit breaker to quickly detect and trip when an overload or short circuit occurs. The compact design has a reduced footprint and offers protection in a small form factor. The circuit breaker also includes a number of integrated safety features, such as a front panel lockout, shunt trip, and an arc flash protection system.

Working Principle

The 9129633200 circuit breaker works on a simple principle. The circuit breaker has two separate contacts. When the current passing through the contacts surpasses a certain threshold, the contacts will separate and open the circuit. This prevents further damage caused by the current by breaking the circuit. The circuit breaker can either be manually or remotely tripped, depending on the application.

Advantages

The 9129633200 circuit breaker has a number of advantages. Its slim-line design and built-in trip units provide excellent protection in a small footprint. The integrated safety features also provide an extra layer of protection. It is also designed for ease of installation and maintenance, making it a cost effective choice.

Conclusion

The 9129633200 circuit breaker is a mid-range circuit breaker designed to protect medium voltage applications. It is suitable for applications with limited space, due to its slim design and built-in trip units. It also offers integrated safety features, such as front panel lockout, shunt trip, and arc flash protection. The circuit breaker works on a simple principle, in which it detects when an overload or short circuit occurs and then opens the circuit to prevent further damage.
