Circuit Breakers

A circuit breaker is a switch designed to protect electrical circuits from faults such as overloads, short circuits, and ground faults. Circuit breakers are used in homes, businesses, automobiles and industrial buildings to protect electrical circuits from damage. One of the most popular types of circuit breakers is the QMB-203-00ENN-3BA.

Application Field

QMB-203-00ENN-3BA circuit breakers are commonly used in residential and commercial applications. The breaker is rated for 277/480 volts and handles up to 50 amps of current. This type of breaker is ideal for applications that require protection from overloads, short circuits and ground faults. It is often used in applications such as air conditioners, refrigerators, dishwashers, water heaters, ranges and motors.

Working Principle

When a circuit breaker is used, the current flowing in the circuit is constantly monitored. When the current exceeds the amount that the breaker is rated for, the breaker will trip and disconnect the circuit. The circuit breaker also monitors the voltage of the circuit. If the voltage rises above the rated value, the breaker will trip and disconnect the circuit.If a short circuit occurs, the breaker will trip immediately, disconnecting the circuit and preventing any further damage. The same is true for ground faults. If an insulation breakdown occurs and the voltage of the circuit rises above the rated value, the breaker will trip again, disconnecting the circuit from the power source and protecting the circuit from further damage.

Conclusion

QMB-203-00ENN-3BA circuit breakers are a reliable and cost-effective way to protect your electrical circuits from damage. It is important to choose the right size and type of breaker for your application to ensure that it does its job properly. The breaker is rated for 277/480 volts and handles up to 50 amps, making it ideal for applications such as air conditioners, refrigerators, dishwashers, water heaters, ranges and motors. It is designed to protect your electrical circuits from overloads, short circuits and ground faults.
