KLM-4 is an electrical specialty fuse that is often used in applications where electrical isolation, lightning protection, current limiting, and UL and cUL listing are required. It is a DC-operated fused circuit breaker that can be manually reset with a single action. The KLM-4 is a thermally-activated, low-voltage fuse with a ridged-wire element that is designed to trip in the event of an over-current condition. The KLM-4 offers both thermal protection and over-current protection.

The working principle of the KLM-4 is quite simple. The KLM-4 serves as an electrical disconnect device that trips when the current level exceeds the pre-set limit. As current passes through the thermal element, the heat generated by the current builds up and triggers the thermal element to open the circuit. Once tripped, the KLM-4 cannot be reset. Once the fault has been corrected, the KLM-4 must be replaced with a new fuse.

The KLM-4 is suitable for use in multiple applications including but not limited to computers, industrial control systems, telecommunications, and other power protection units. In addition to current-limiting protection, it also provides Over-current Protection (OCP) for users. This OCP prevents any short-circuiting device from malfunctioning and can prevent further system damages arising from thermal overload or short-circuiting.

The KLM-4 also provides UL and cUL listing, granted from Underwriters Laboratories and Canadian Standards Association, that provides users the assurance that their electrical equipment meets the necessary safety requirements. This certification is important because in the event of a failure, it indicates to the user that the fuse has met certain safety standards.

The KLM-4 allows users to replace fuses quickly and without difficulty. A convenient knob that allows users to reset the KLM-4 manually allows for a quick and easy replacement. This cost and time saving feature is beneficial to users and simplifies the task of replacing the fuse.

The KLM-4 is an excellent choice of fuse for many applications where current limiting, electrical isolation, and UL and cUL listing are necessary. With its working principle of thermal-activation, convenient and easy resetting feature, and UL and cUL listing, the KLM-4 ensures a safe and secure electrical system and prevents damages that could arise from over-current or short-circuiting.
