Midget Fuses and Fuse Holders

PCF series of fast-acting direct-mountable fuses address the need for electrical protection at the PC board. These fuses help PCB users/manufacturers reduce parts by eliminating clips and/or fuseholders and allowing automated assembly. PCF fuses can be used for the protection of main frame power boards, small circuit breakers with low-interrupting capabilities and other critical components. PCF fuses bring greatly increased ampere, voltage and interrupting ratings to the board itself and are UL Component Recognized.

Mersen USM Series UltraSafe Modular Fuse holders introduce a new level of safety for Midget 1-1/2" x 13/32" AC and DC-rated fuses up to 30 amperes. UltraSafe holders qualify as “Finger-safe” under IEC and DIN standards to an IP20 grade of protection, including fuse changing (with the flick of a finger). UltraSafe holders are available in 1, 2, 3 or 4 poles, with or without visual blown-fuse indicators in each pole. Multipole units can also be field assembled by ordering pin-tie handles.
UltraSafe holders save up to 15% mounting space and any combination can be snapped onto 35mm DIN-rail for extra savings in panel building time. UltraSafe body material is tough and durable polyamide, with exceptional insulating properties.

Mersen’s USGM series fuse holders 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 fuse holder, delivering the best of both technologies to its customers. Now you can experience the combined benefits of safety, ease-of-use, labor savings and reliability of UltraSafe fuse holders and spring pressure technology.

Mersen has developed a true 1000VAC/DC fuse designed to protect both analog and digital multi-meters. These fuses cover all the industry's multi-meter requirements in three easy to use amperage ratings. Good for 1000 volts AC and DC, the FSM line of Ferraz Shawmut fuses are designed for the power electronics metering and controls market.

SBS midget fast-acting fuses were developed in response to the industry's demand for smaller equipment and components. They are the only fuses in their size with a full 600VAC rating for all ampere ratings by UL Standard 248-14 and CSA No. 59.2, and are the only fuses of this size with an interrupting rating of 100kA RMS, compared to 10kA on other brands.

PCT series of time-delay direct-mountable fuses address the need for electrical protection at the PC board. These fuses help PCB users/manufacturers reduce parts by eliminating clips and/or fuseholders and allowing automated assembly. PCT fuses can be used for the protection of main frame power boards, small circuit breakers with low-interrupting capabilities and other critical components. PCF fuses bring greatly increased ampere, voltage and interrupting ratings to the board itself and are UL Component Recognized.

PCS series of semiconductor direct-mountable fuses address the need for electrical protection at the PC board. These fuses help PCB users/manufacturers reduce parts by eliminating clips and/or fuseholders and allowing automated assembly. PCS fuses are AC and DC rated and are extremely current-limiting. They will protect semiconductors, main frame boards, circuit breakers with low interrupting capabilities and other critical components. PCS fuses bring I2t protection, higher ampere, voltage and interrupting ratings and are UL Component Recognized.

Mersen GPM Panel Mount Fuse Holders are in sizes to accommodate 5x20 mm, 1/4"x1-1/4", Class CC and Midget (1-1/2"x13/32") fuses. All 30A holders have glass-filled polyester insulators for extra dependability and trouble-free installation. Patented design allows same body to accept screw or bayonet knob. Flange design allows front or rear mounting. The 10A and 15A holders are for front mounting only.

GFN midget indicating fuses are available in 34 ratings from 1/10A through 30A. These time-delay fuses have built-in blown fuse indicators which pop out at the end of the fuse to visually indicate when the fuse has operated. Indicators may be used to trip a switch for remote as well as visual indication. (Not for Branch Circuit Protection).

Mersen’s complete line of single and dual pole in-line fuse holders accommodate either 1-1/2" x 13/32" (10 x 38 mm) midget or Class CC fuses. The fuse holders are designed for quick installation. Securing nuts or screws are captive thus speeding installation by reducing the need to locate and assemble loose components in the field. Three internal O-rings per pole seal the fuse holder providing a waterresistant compartment for the fuse. The captive O-rings are colored (blue for single pole and red for dual pole) for quick detection. Optional cone shaped insulator boots can be slipped on to provide a watertight seal (breakaway versions come with boots standard). Both single and dual pole versions have an optional breakaway feature which safely disconnects the load in case of a pole knockdown. Fuses remain safely encapsulated within the watertight fuse holder on the load side. Once the pole has been reinstalled the fuse holder can be easily reconnected.
