Description

This fuse was specially developed for SELV applications with high rated currents for highest breaking capacity demands. Thanks to its design, the fuses tripping time minimizes excessive temperature dissipation at 2x rated current.

Unique Selling Proposition

High breaking capacity up to 2000A
Safe tripping in 10s at twice the rated current
High range of operating temperature
Small component height of 4.7 mm

Applications

Automotive
Telecom equipment
Datacenter appliances
Power tools
