SCCR-rated terminal fuse blocks: Class CC fuse protection

Weidmuller offers new DIN-rail mounted fuse terminal blocks for equipment requiring fast overload protection. The WSI 25 fuse terminal blocks accept 13/32 x 1.5-in. (10.3 x 38 mm) Class CC fuses and have a short circuit current rating (SCCR) of 200 kA. They are designed for high current and high voltage applications, making them ideal for protecting components such as transformers, motors and solenoids.

Weidmuller offers new DIN-rail mounted fuse terminal blocks for equipment requiring fast overload protection. The WSI 25 fuse terminal blocks accept 13/32 x 1.5-in. (10.3 x 38 mm) Class CC fuses and have a short circuit current rating (SCCR) of 200 kA. They are designed for high current and high voltage applications, making them ideal for protecting components such as transformers, motors and solenoids.

The WSI 25 terminal fuse blocks are compact and touch-safe, with an easy-to-access lever for quick and safe fuse replacement. The Class CC fuse holder accommodates a variety of fuse ratings designed to offer circuit protection for specific application requirements. Class CC type fuses are fast acting and offer the highest current limiting performance available for their size. A rejection feature integrated into the holder prevents the insertion of a lower rated or non-Class CC fuse. An optional LED blown fuse indicator helps reduce troubleshooting time with fast and easy failure identification.

Weidmuller’s WSI 25 terminal fuse blocks are available in 1, 2 or 3 pole configurations, and feature a vented housing to reduce internal heating and extend fuse life. Each of the new blocks accept multiple wire inputs ranging from 18 AWG to 4 AWG, and are UL and CSA rated to 600 V, 30A.
