KLKR.125T

KLKR.125T is a thermal circuit protection device. It is a two-component, closed-end, temperature sensing fuse that helps protect against short circuits and over-currents for applications in the automotive, industrial, and consumer markets. It is a fast-acting, non-resettable fuse with a dual-element construction that provides consistent performance without the need for complex time-dependent systems. The KLKR.125T fuse has a UL recognized rating of 125 A.

Applications

The KLKR.125T fuse is designed for applications where it is necessary to protect against short circuits and over-currents. It is used in the automotive, industrial, and consumer markets. Examples include, but are not limited to, industrial control systems, lighting and motor control systems, and instrumentation equipment. In addition, the fuse can be used to protect starter motors, generators, and motors. It can also provide over-current protection in high-power applications such as power supplies, UPS systems, and high-power charging systems.

Working Principle

The KLKR.125T fuse works by sensing temperature and then activating a circuit breaker to open the circuit when it reaches a preset temperature. The fuse is made up of two components: a metallic strip and a thermal element. The metallic strip is connected to the circuit and the thermal element is connected to a spring-loaded plunger. When the electrical current in the circuit exceeds the preset rating, the metallic strip heats up and the thermal element melts. This causes the plunger to release, allowing the circuit to open. The fuse is then reset once the current is reduced to an acceptable level.

Conclusion

KLKR.125T is a two-component, closed-end, temperature sensing fuse that helps protect against short circuits and over-currents. It is designed for applications where it is necessary to provide protection from short circuits and over-currents. It is used in the automotive, industrial, and consumer markets and can be used to protect starter motors, generators, and motors, as well as power supplies, UPS systems, and high-power charging systems. The fuse operates by sensing temperature, melting a thermal element, and then activating a circuit breaker to open the circuit.
