Description

Screw-cap fuse terminals

UK10-DREHSI terminals combine a screw-cap G-type 5×20mm fuse holder with two M4 screw connections. Each terminal has one row and one fuse circuit. Plain and indicator versions share a 12mm-wide body for U35/7.5 DIN rail.

The plain terminal has an 800V body insulation rating alongside its 500V fuse-circuit operating rating. The plain and LA/250 versions have a 10A maximum load current; LED/24 has a 10A nominal rating without a separately specified maximum. Indicator circuits must remain within their own voltage ranges. Use-group ratings do not increase the installed fuse rating.
