BUSSMANN Effective April 2017 Technical Data 2127 Supersedes December 2015 SERIES HEB breakaway and non-breakaway in-line fuse holders for UL 13/32” x 1-1/2” supplemental fuses Use these part numbers to order insulating boots for a non-breakaway HEB holder: Description Catalog no. Single conductor 2A0660 Dual conductor 2A0661 Boot reference: Catalog Symbol: HEB* Description: 0.8 The Bussmann™ series of HEB submersible, single-pole 4.1 (ø20) (104) in-line fuse holders for UL 13/32” x 1-1/2” supplemental fuses. Available in non-breakaway and breakaway versions with an array of terminal options to meet application needs. Breakaway versions come with insulating boots to provide submersibility per UL IP67. Non-breakaway versions require 1.3 4.7 ordering optional insulating boots for submersibility. (ø33) (119) Recommended fuses: Installation instructions: BAF, FNM, FNQ, KLM and KTK Strip wire insulation equal to the depth of the crimp or screw terminal. Torque screw terminal to 35 Lb-In (3.9 N•m) or Ratings: crimp terminal twice, spacing crimps a distance of one-third Volts: 600V from each end (as shown below) using an appropriate crimp tool and die. See page 5 for recommended crimping tools. Amps: up to 30A limited by conductor size Withstand: 200kA RMS Sym. Crimp terminal twice at locations 1/3 distance Agency information: from each end ® UL Recognized, Guide IZLT2, File E14853 ® CSA Certified, Class 622501, File 47235 † CE, RoHS compliant Coupling nut torque: Strip wire insulation to depth of terminal 10-20 Lb-In (1.1-2.2 N•m) Related products: Operating and storage temperature: Catalog Data -40°F (-40°C) to 221°F (105°C) no. Description sheet no. Insulating boots: Two-pole supplemental in-line fuse HEX 2126 holder Two insulating boots come standard with the breakaway One-pole Class CC in-line fuse holder configurations. Insulating boots are not included HEZ 2130 holder as standard with non-breakaway holders. Two insulating Two-pole Class CC in-line fuse boots must be ordered separately, if required, for each HEY 2126 holder non-breakaway holder ordered. When insulating boots are One-pole in-line, permanently utilized, extra heat retention requires that fuses are sized at a HET 2125 installed neutral minimum of 200% of the RMS load current. 13/32” x 1-1/2” neutral dummy link NNB — (not a fuse) * The Bussmann series HEB in-line fuse holders are the legacy Bussmann TRON™ HEB in-line fuse holders. † See terminal data tables for exceptions.
