8340-T120-K1M1-ALH0-0.25A

Introduction

Circuit breakers interrupt the flow of current in a circuit in order to protect it from overloads and shorts. A 8340-T120-K1M1-ALH0-0.25A circuit breaker is a specific type of circuit breaker designed to provide supplemental protection for certain applications. In this article, we will examine the application field and working principle of the 8340-T120-K1M1-ALH0-0.25A circuit breaker.

Application Field

The 8340-T120-K1M1-ALH0-0.25A circuit breaker is generally used in circuits that have a low current rating (0.25A) and a high overcurrent protection requirement such as small household appliances, electronic circuits, and other sensitive circuits. This circuit breaker has a thermal-magnetic trip mechanism which can sense both low and high overloads, providing dual protection for sensitive circuits. The low current rating and overload protection make it the ideal circuit breaker for protecting against short circuits and overloading of the circuit.

Working Principle

The 8340-T120-K1M1-ALH0-0.25A circuit breaker works using the principle of threshold protection. This threshold protection is provided by the thermal-magnetic trip mechanism that is built into the circuit breaker. This mechanism is designed to detect excessive current flow and anytime excessive current is detected, it opens the circuit, thus interrupting the flow of current and preventing the overload or short circuit from damaging the protected circuit.

The thermal-magnetic trip mechanism is designed to sense both low and high overloads. When the current rating of the circuit reaches the set threshold, the thermal trip mechanism will kick-in immediately. This will cause the trip mechanism to open the circuit, effectively cutting off the supply of electricity to the circuit. In addition, the thermal-magnetic trip mechanism is designed so that when the temperature of the circuit reaches a certain level, the magnetic trip mechanism will kick-in, causing the circuitbreaker to open again. This provides an added level of protection in case of a catastrophic failure of the protected circuit.

Conclusion

The 8340-T120-K1M1-ALH0-0.25A circuit breaker is a specific type of circuit breaker designed to provide supplemental protection for certain applications. It has a low current rating of 0.25A and a thermal-magnetic trip mechanism which can sense both low and high overloads and can open the circuit to protect it from overloads and shorts. This circuit breaker is ideal for protecting small household appliances, electronic circuits, and other sensitive circuits from overloads and short-circuits.
