"KLA Fuse" is a product designed to be used in combination with MOVs or Class II SPDs that comply with JIS standards (JISC5381-1). In the event that the MOV/SPD deteriorates, it disconnects from the circuit. Compared to conventional fuses for separating Class II SPDs, it is more compact. 【Features】 ■ High surge capacity. ■ Complies with Class II specifications. ■ Low rated current, making coordination with upstream breakers easy. *For more details, please refer to the PDF documentation or feel free to contact us.

The "Alarm Fuse (FZ)" is a protective device that safeguards electronic equipment from surges. It compactly combines a zinc oxide varistor with a fuse, possessing high voltage non-linearity and surge absorption capability, to absorb and limit surge voltage. It is a plug-in type, making it easy to attach and detach. 【Features】 ■ High surge capacity ■ Low limiting voltage ■ Indicates varistor damage and activates an alarm *For more details, please refer to the PDF document or feel free to contact us.

The "Alarm Fuse Unit (FZU)" is a product that is compatible with our P4 type alarm fuse receptacle. In the event of varistor degradation due to excessive surges, the fuse within the FZ unit disconnects the varistor to prevent secondary damage. This unit protects between lines and between each line and ground. 【Features】 ■ It is a plug-in type for our P4 type fuse receptacle, making replacement easy. ■ Monitors the fuse status with alarm contacts and a display window. ■ Allows for prompt response in the event of varistor degradation. *For more details, please refer to the PDF document or feel free to contact us.
