They are current limiting with a 200,000A interrupting rating, yet will carry low cable overloads which are handled by standard protective devices. Cable Protectors are rated in terms of cable size and material (Al or Cu). Heavier duty CPH Cable Protectors are available on special order. Heat shrinkable (HS) tubing can be specified for field installation. For cables smaller than 4/0, Class J fuses can be used.

General Purpose FusesIL Indicator
The new “IL” indicator, provides a blown fuse indication system which does not sacrifice the excellent I2t characteristics of Ferraz fuses. Its low voltage design requires just 0.9 volts to activate the indicator, thus insuring reliable fuse performance under all conditions. The red pop up button is located in the center of the fuse body for ease of visibility and optimum voltage isolation. Interference with buss bar and cable connection is significantly less than other designs. The addition of the “IL” indicator provides blown fuse indication on virtually all Ferraz fuses. Optional auxiliary microswitches for remote signaling are also available for use with the “IL” indicator.

UltraSafe Fuse HoldersUltrasafe 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 Fuse HoldersUltrasafe™ 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.
