KLKR004.T is a type of specialty fuse. It is a high performance fuse used for DC voltage and solar energy applications. The fuse contains an element made of an ultra-thin metal strip, which melts when the current through the fuse exceeds the rated current, thus cutting off the electric circuit.

KLKR004.T is specially designed for photovoltaic string protection. It can effectively protect the solar photovoltaic string and corresponding inverter from overcurrent during the operation of photovoltaic system. It is suitable for use in 1000V DC photovoltaic system. Its rated current varies from 0A to 40A. It also has excellent physical features, including small size and light weight.

In photovoltaic systems, the KLKR004.T increases the lifetime of the electronic components and reduces maintenance costs by preventing damage from over currents. This ensures that the system remains stable and reliable. Additionally, its frosted feature, temperature resistance, arc-exhaust design, and easy installation make it a favorable choice for many photovoltaic applications.

KLKR004.T is especially popular due to its combined features of both over voltage and current trip protection. It has a delayed over voltage trip characteristic, which means it will shut off the photovoltaic module when the voltage reaches a maximum pre-set value. Similarly, when the current reaches a certain pre-set level, the over-current trip feature ensures that the photovoltaic module is shut off until the over current situation returns to a normal operating condition. Moreover, the fuse is capable of operating at temperatures up to 150 degrees Celsius, and has an operating voltage of 1000V DC.

The working principle of KLKR004.T is based on the thermal-magnetic element. When the current flowing through the fuse exceeds its rated current, the temperature of the element increases and causes the element to experience an increase in electrical resistance. As a result, the increased resistance results in the fuse being blown, thus cutting off the electric circuit. The duration of melting depends on the section of the element, the ambient temperature, and the resistance of the path.

KLKR004.T is an ideal product for low voltage and high current applications. It is highly reliable and efficient for both home and commercial applications. Its high performance, combined with its small size, make it an ideal choice for any photovoltaic system. Furthermore, its over voltage and current trip protection features make it the perfect choice for safety and reliability in any environment.
