APL111-21631-12

Circuit Breakers, such as the APL111-21631-12, are among the most essential components of any electrical system. By preventing overloading and malfunction due to power surges, they ensure the uninterrupted operation of both residential and industrial electronic circuits. Through its dual function of tripping and resetting, a circuit breaker provides crucial protection against short circuits, overloads and various other hazardous electric events.

The APL111-21631-12 has a voltage rating of 120-240V and current rating of 6A and is typically used in circuit breakers for residential spaces. Its operating principles are based on the thermal and magnetic actuation. This type of circuit breaker features a soft-magnetic core and a heat-sensitive bimetallic strip. When an overload occurs, current passes through the solenoid which causes the core to become magnetized. The attached hammer then hits the bimetallic strip, which is pliable due to its increased temperature, and trips the circuit breaker. As soon as the bimetallic strip cools down, it flattens and the contact spring in the circuit breaker will automatically return to its original position.

The combination of the thermal-magnetic actuation design and simple operation makes this type of circuit breaker extremely reliable and suitable for a broad range of applications, including overload and short circuit protection for lighting, motor, HVAC, power tools, kitchen appliances and other household equipment that use 120-240V AC current. It is also widely used in industrial applications, such as overload protection for equipment and circuits in power distribution boards and automation control systems.

In addition to its residential and commercial applications, the APL111-21631-12 circuit breaker is also capable of providing superior performance in demanding industrial applications. It is ideal for applications that require high levels of vibration and shock resistance, such as in aerospace and marine environments. Moreover, due to its non-contact nature it eliminates the risk of contact arcing, which is common with traditional contact type circuit breakers.

The APL111-21631-12 circuit breaker is an excellent example of a reliable, high-performance circuit protection solution that offers superior protection for residential, commercial, and industrial applications. Its thermal-magnetic actuation design and simple operation ensure reliable protection against overload, short circuits and other hazardous electric events while its lightweight form factor and non-contact operation make it suitable for a broad range of applications.
