BUSSMANN Effective January 2019 Technical Data 2127 Supersedes April 2017 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, 4.1 (20) (104) single-pole 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 1.3 4.7 provide submersibility per UL IP67. Non-breakaway (33) (119) versions require ordering optional insulating boots Installation instructions for submersibility. Strip wire insulation equal to the depth of the Recommended fuses crimp or screw terminal. Torque screw terminal to BAF, FNM, FNQ, KLM and KTK 35 lb-In (3.9 Nm) or crimp terminal twice, spacing crimps a distance of one-third from each end (as Ratings shown below) using an appropriate crimp tool and Volts: 600 V die. See page 5 for recommended crimping tools. Amps: up to 30 A limited by conductor size Crimp terminal twice at locations 1/3 distance Withstand: 200 kA RMS Sym. from each end Agency information UL Recognized, Guide IZLT2, File E14853 CSA Certified, Class 622501, File 47235 CE, RoHS compliant Strip wire insulation to depth of terminal Coupling nut torque Related products: 10-20 lb-In (1.1-2.2 Nm) Operating and storage temperature Catalog Data no. Description sheet no. -40F (-40C) to 221F (105C) Two-pole supplemental in-line HEX 2126 Insulating boots fuse holder One-pole Class CC in-line Two insulating boots come standard with the HEZ 2130 fuse holder breakaway holder configurations. Insulating boots are not included as standard with non-breakaway Two-pole Class CC in-line HEY 2126 fuse holder holders. Two insulating boots must be ordered separately, if required, for each non-breakaway One-pole in-line, permanently HET 2125 installed neutral holder ordered. When insulating boots are utilized, extra heat retention requires that fuses are sized 13/32 x 1-1/2 neutral NNB dummy link (not a fuse) at a minimum of 200% of the RMS load current. * The Bussmann series HEB in-line fuse holders are the legacy Bussmann TRON HEB in-line fuse holders. See terminal data tables for exceptions.Technical Data 2127 Bussmann series HEB breakaway and non-breakaway Effective January 2019 in-line fuse holders for UL 13/32 x 1-1/2 supplemental fuses Non-breakaway catalog number system To order: Specify catalog symbol HEB and the loadside terminal code. Then select a lineside HEB - A A terminal code that is available with the loadside terminal. Example: HEB-BB defines a non-breakaway holder with a loadside copper crimp terminal for a single 6 or two 10 wires with a lineside copper crimp terminal for a single 6 or two 10 wires. Agency Info.
