Local Distributor & Supplier of Fuses, Fuse Holders & Power Distribution Blocks

We have nearly 100 years of experience in electrical parts distribution & supply for our clients in Buffalo, Rochester, Batavia and Niagara Falls, New York area surrounding L.A. Woolley Electric, Inc. We are proud to carry fine Mersen products, including fuses, fuse holders, and power distribution blocks. For instance, the Amp-Trap 2000® SmartSpot AJT fuses feature a host of benefits, including a solid state visual blown fuse indicator, a time-delay for motor starting and transformer in rush, and has a 300kA interrupting rating. Also available are the USCC & USM UltraSafeTM Fuseholders. These products introduce a new level of safety for class cc and midget AC and DC-rated fuses up to 30 amperes. Mersen also carries high quality power distribution blocks like the finger-safe FSPDB Series with an aluminum connector. A fully insulated block ensures that no one can touch live parts, while recessed termination screws and wire openings provide IP20 grade protection and also qualify as "finger-safe" per IEC 529.

Product Features & Benefits

  • Fuses now provide a visual open fuse indicator
  • Current-limiting time-delay fuses are engineered for over-current protection of motors and transformers, service entrance equipment, feeder and branch circuits
  • Tri-Onic® TRM time-delay midget fuses are rated 250 volts. They provide supplemental protection of small motors, small transformers and other high inrush loads, plus many other 250 volt applications
  • Introduce a new level of safety for Class CC (USCC) and Midget 1-1/2" x 13/32" (USM) AC and DC-rated fuses up to 30 amperes
  • More current-limiting than any other Class L fuse on the market
  • Tri-Onic® DC fuse series is designed for DC circuit protection in surface and underground mines
  • Amp-Trap® has a wide range of applications not covered by other midget fuses.
  • Unique, compact design suited for use with 45mm wide IEC contactors
  • Visual open fuse indicator
  • The High Speed J (HSJ) fuse was designed for the starting characteristics of solid state motor controllers
  • One-time (OTM) midget fuses provide low-cost protection for 250 volt AC general purpose lighting, heating, control circuits, etc. where time-delay is not required
  • Introduce a new level of safety and ease for installing or replacing Class J fuses
  • No Damage protection to your facility's increasingly sensitive branch circuit components and small motors
  • A4J Class J fuses deliver excellent current-limiting protection to a wide variety of applications
  • GFN midget indicating fuses have built-in blown fuse indicators which pop out at the end of the fuse to visually indicate when the fuse has operated to open the circuit
  • 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
  • Time-delay characteristics ideally suited for the high inrush currents of control transformers, solenoids, and similar inductive loads
  • When it comes to protecting service entrance equipment, feeder circuits, and circuit breakers, A4BY fuses are the industry's favorite
  • Mersen DCT fuses were developed to meet requirements coming from new applications such as protection of photovoltaic cells, multi meters and compact on board traction equipment for auxiliary circuits
  • A choice of screw, pressure plate, box and special order stud connectors fit a wi de range of stranded or solid copper or aluminum conductors
  • Current-limiting ability and a wide range of ratings (from 1 to 600 Amperes)
  • The high interrupting rating of A4BT current-limiting fuses is ideally suited for protecting mains, feeders, and general circuits
  • PCF series of fast-acting direct-mountable fuses addresses the increasing need for electrical protection at the PC board
  • Fuse boxes are available to accommodate all midget fuses

Product Features & Benefits

  • Intended to hold and safely enclose 1-1/2" x 13/32" midget or Class CC fuses for insertion or removal from fuse clips, making fuse installation easy and safe without the use of a standard fuse puller.
  • No-fuse, fail-safe surge suppressor
  • Holds and safely encloses 1-1/2" x 13/32" midget or class CC fuse but with a low profile in height so it takes less room where space is restricted
  • High short circuit rating and a thermally protected MOV, which eliminates the need for additional overcurrent protection devices
  • Provides quick mounting for all Mersen 303 series midget and class CC fuse blocks to all symmetrical 35mm DIN or asymmetry rical 32mm "G" rail
  • Fail-safe self-protected design, visual indicator and a small footprint
  • New level of safety and ease for installing power distribution blocks.
  • DIN-rail mountable
  • Power Distribution Blocks afford a safe, convenient way of splicing cables, splitting primary power into a variety of secondary circuits or providing a fixed junction tap-off point
  • Economical replacement for the former surge arrestor category
  • Polycarbonate safety covers provide dead-front protection
  • TPMOV® technology eliminates common failure modes that occur in the field with standard metal oxide varistors
