Mersen's complete line of single and dual pole in-line fuseholders with integral neutral link. The fuseholders 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 fuseholder providing a water-resistant 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 fuseholder can be easily reconnected. 600 Volts 30 Amps 2 pole 81-81 B1 series.

The Surge-Trap® Type 1 XT Series offers Advanced Technology. The XT features TPMOV® technology inside making it the safest product available. With line or load side installation flexibility, this unit is a great fit from the service entrance all the way down to each distribution and/or branch panel. 230/400 Volts 3P Wye system type with alarm .

The 690/700V Protistor® fuse-links provide maximum flexibility in equipment design and ultimate protection for small power conversion equipment. The Protistor® gR have been engineered to provide full range protection to eliminate all overloads and semiconductor fault. Fuses are assembled with pure silver, die-cut elements embedded in solidified sand, which helps control arcing characteristics for a lower I2t and high interrupting rating level. All contact surfaces are silver plated and all hardware is non-magnetic. Each fuse-link can be equipped with a low voltage trip-indicator which can operate a field mountable microswitch. 690 Volts 40 Amps 000 gRB D08 series.
