Introduction

Circuit breakers are an important part of electrical systems. They are used to protect wiring and prevent damage from overheating, short circuits, and other faults. 4435.0202 is a switch-trip circuit breaker specifically designed for use in residential and commercial applications. This article will discuss the application fields and working principle of 4435.0202 circuit breaker.

Application Field for 4435.0202 Circuit Breaker

The 4435.0202 circuit breakers are primarily used in residential and commercial applications, such as houses, schools, and other types of buildings. They can also be used for outdoor-rated applications, but should only be used when the National Electrical Code (NEC) allows it. These circuit breakers are UL-listed products and are suitable for use as a circuit breaker in 120/240-volt manufacture-installed branch circuit panel boards.

Working Principle of 4435.0202 Circuit Breaker

The basic working principle of a circuit breaker is to detect problems in the electrical system and automatically break the circuit. The 4435.0202 circuit breaker is a switch-trip type of circuit breaker that is designed to sense an overcurrent in the electrical system and break the circuit when it detects a fault. It works by using a bimetallic strip that senses the temperature of the current in the circuit. When the strip heats up due to an overload, it bends and causes the contacts on the circuit breaker to separate and disconnect the circuit. Additionally, these circuit breakers have a reset switch that allows you to reset the circuit breaker and turn the power back on.

Conclusion

The 4435.0202 circuit breaker is a switch-trip type of circuit breaker designed for residential and commercial applications. It is UL-listed and is suitable for use in 120/240-volt branch circuit panel board installations. The 4435.0202 circuit breaker works by using a bimetallic strip to sense changes in temperature due to current overloads and automatically breaking the circuit when an overload is detected. It also has a reset switch to reset the circuit breaker and turn the power back on when the fault is cleared.
