KLM-25

An electrical specialty fuse is an important device used to protect the circuit from over-voltage and over-current of electrical components. The KLM-25 fuse is a popular one-time over-voltage protection device which is widely used in electrical equipment such as air-conditioning, heating and commercial lighting. It provides over-current and over-voltage protection for electric system components in a cost-effective manner.

Application Field

KLM-25 fuses have been designed to meet a wide range of conditions encountered in various commercial and industrial applications. While they are mainly used for protecting current-carrying conductors against high current surges, they also offer extensive protection for other loads such as motor drives, transformers, circuits, and other equipment. They can also be used as common air conditioning systems and boilers, to ensure the safe operation of the appliance.

KLM-25 can also be used for protecting electric appliance motors such as mixers, pumps, fans, and other equipment from the most common over-current applications. They can be easily installed by operators because of their simple design. Furthermore, they provide reliable protection from over-voltages that may occur due to rapid voltage spikes.

As KLM-25 fuses do not require any maintenance and have a one-time action, they are widely used in residential, commercial, and industrial settings. Moreover, the fuses are designed to work as a secondary layer of protection for electric power safety applications and are UL Recognized and CSA Approved. This makes KLM-25 popular for electric motor and circuit protection.

Working Principle

The working principle of a KLM-25 fuse is based on a rapid thermal response material that is embedded in a flux-filled copper channel or path. This material swells when exposed to excessive current flow, causing the fuse link to move away from the contact. This prevents the current from flowing through the circuit, protecting it from further damage.

KLM-25 fuses are designed to respond almost instantly, ensuring that the circuit is quickly disconnected to prevent catastrophic damage. This protective mechanism has the best performance for over-current and over-voltage protection. In normal operation, KLM-25 fuses are dimensioned to allow the same maximum current flow that the component in the circuit can handle without over-voltage or over-current.

In addition, the KLM-25 fuse is able to protect short circuits and overload currents of up to 8 times the rated current. The unique design of the KLM-25 fuse ensures a high level of safety and reliability as well as cost efficiency, making it an ideal solution for over-current and over-voltage protection.

Conclusion

KLM-25 fuses are widely used for protecting electric motor and circuit components from over-voltage and over-current applications. They are designed to provide reliable over-current and over-voltage protection, quickly disconnecting a circuit in the event of a fault while providing a long-term protection from over-current and over-voltage events. The low maintenance and one-time action features make KLM-25 popular for electric motor and circuit protection.
