Ultrasafe Fuseholders - USFM Series
The Ultrasafe Fuseholders - USFM Series is part of the Mersen (formerly Ferraz Shawmut) ultrasafe fuse holders line, distributed by Gross Automation.
Ferraz Shawmut ULTRASAFE Fuse Modules have a unique, compact design suited for use with 45mm wide IEC contactors. These modules also offer other features not found on other Class CC and midget Ultrasafe fuse holders such as an auxiliary contact option. When the auxiliary is wired to an adjacent contactor the load is dropped out by the contactor immediately once someone tries to open the fuse extractor handle. Additionally, the fuse module features padlock capabilities, compact busbars for line side terminations, and tool free removal from DIN rail. Yet the fuse modules still incorporate well known Ultrasafe features such as IP20 protection, easy operating fuse extraction handles and an open fuse visual indication option.
