Introduction

The 4230-T130-K0BU-7A circuit breaker is an essential device in electrical protection systems. It is typically used to protect equipment and machinery from electrical overloads and short circuits. Circuit breakers are rated by their voltage and current ranges and can be manual, magnetic or thermal.

Application Field

The 4230-T130-K0BU-7A circuit breaker is usually used for low voltage, heavy-duty applications such as industrial switches, industrial electrical cabinet, machine and clinical safety circuits, railway lines and so on. It is also suitable for motors, generators and many sophisticated electrical equipment, and is approved by UL 489 and CSA C22.1.

Working Principle

Circuit breakers work because they contain an internal set of contacts that open when a certain amount of current passes through them. When the current reaches a predetermined level, the contacts separate, "breaking" the circuit and preventing further current flow. This prevents accidents due to electric shock or fires caused by overloading electrical wiring.

There are several types of circuit breakers, each with their own working principles. The 4230-T130-K0BU-7A is a thermal-magnetic tripping device. It consists of an electromagnet and a thermal overload relay. When an overload current flows in the circuit, the electromagnet is energized, open the circuit breaker contacts and cut off the current. When operated beyond its specified range, the current heats the thermal overload relay which triggers the trip mechanism to open its contacts. This type of circuit breaker is suitable for heavy duty applications where a high level of protection is required.

Conclusion

The 4230-T130-K0BU-7A circuit breaker is an essential device in electrical protection systems. It is primarily used for low voltage, heavy-duty applications such as industrial switches, industrial electrical cabinet, machine and clinical safety circuits, railway lines, motors, generators and many sophisticated electrical equipment. It is a thermal-magnetic tripping device which consists of an electromagnet and a thermal overload relay. When an overload current flows in the circuit, the electromagnet is energized, open the circuit breaker contacts and cut off the current. This ensures safety and prevents accidents due to electric shock or fires caused by overloads.
