Ultrasafe Fuseholders - US14 Series
Ferraz Shawmut ULTRASAFE modular 750 volt Fuse Holders offer the highest levels of safety and features for 14 x 51 mm fuses. Like all ULTRASAFE holders, they qualify as "finger safe" to an IP20 grade of protection under IEC standards, including fuse changing (with the flick of a finger). The US14 range is available in 1, 2 or 3 pole units, with or without blown-fuse indicator lights in each pole. These holders come standard with a mechanical indicator that shows fuse presence. If a striker fuse is used, this mechanical indicator will also indicate a blown fuse. Microswitches can be supplied with the holders (or ordered separately for field installation) to allow remote communication. These holders also feature padlocking capabilities, DIN rail mounting with our unique latching system to allow re-positioning, and the capability to be joined as multiple poles in the field.

Ultrasafe Fuseholders - USFM Series
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.

Ultrasafe™ Fuseholders - USGCC & USGM Series
The new USGCC and USGM fuseholders are equipped with industry-proven and patented CAGE CLAMP® technology. This screw-less, spring pressure, wire termination technology has over 25 years of field experience and acceptance and can reduce wire installation time and cost by up to 75%. The spring terminal technology significantly improves system reliability by maintaining a very low contact resistance, easily withstanding corrosion, vibration and temperature cycling. The technology also eliminates the need for routine torque maintenance required by standard screw-type terminations. Mersen is the first manufacturer to offer this technology in a power fuseholder. Mersen USGCC and USGM fuseholders feature IP20 finger-safe protection, a compact footprint, DIN-rail mounting and quick, easy and tool free fuse change-outs. The fuseholders are available and designed for use with class CC, midget and photovoltaic fuses at ratings up to 32A and 750VAC / 1000VDC. Fuseholders are also tested and certified by global standards organizations Underwriters Laboratories (UL), Canadian Standards Association (CSA) and International Electroctechnical Commission (IEC). Mersen's new USGCC & USGM series fuseholders deliver the ultimate ease-of-use, time (labor) saving and reliable solution available in the marketplace. Mersen is the first manufacturer to offer screw-less, spring pressure, wire termination technology into a power fuseholder, delivering the best of both technologies to its customers. These revolutionary fuseholders now allow you to experience the benefit of safety, ease-of-use, labor savings and spring pressure technology.
