Effective January 2016 Supersedes September 2012 Technical Data 2130 BUSSMANN SERIES HEZ breakaway and non-breakaway in-line rejection fuse holders for UL Class CC fuses Use these part numbers to order insulating boots for a non-breakaway HEZ holder: Catalog Symbol: HEZ Description Part no. Single conductor 2A0660 Dual conductor 2A0661 Boot reference: Description: Bussmann series HEZ submersible, single-pole in-line rejection fuse holders are for UL Class CC fuses. They are 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 ordering optional insulating boots for submersibility. ® Recommended fuses: Catalog symbol LP-CC Operation Time-delay FNQ-R KTK-R Fast-acting 0.8 (ø20) 4.1 (104) 1.3 (ø33) 4.7 (119) Installation instructions: Data sheet No. 1023 1014 1015 Ratings: Volts: 600V Amps: up to 30A limited by conductor size 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 crimp terminal twice, spacing crimps a distance of one-third from each end (as shown below) using an appropriate crimp tool and die. See page 3 for recommended crimping tools. Crimp terminal twice at locations 1/3 distance from each end Withstand: 200kA RMS Sym. Agency information: UL® Listed, Guide IZLT, File E14853 CSA® Certified, Class 6225-01, File 47235 CE, RoHS compliant Coupling nut torque: 10-20 Lb-In (1.1-2.2 N•m) Operating and storage temperature: Strip wire insulation to depth of terminal Related products: Catalog no. Description Data sheet no. -40°F (-40°C) to 221°F (105°C) HEX Two-pole supplemental in-line 2126 fuse holder Insulating boots: HEB One-pole supplemental in-line 2127 fuse holder HEY Two-pole Class CC in-line fuse holder HET One-pole in-line, permanently 2125 installed neutral NNB-R Class CC neutral dummy link (not a fuse) Two insulating boots come standard with the breakaway holder configurations. Insulating boots are not included as standard with non-breakaway holders. Two insulating boots must be ordered separately, if required, for each non-breakaway holder ordered. When insulating boots are utilized, extra heat retention requires that fuses are sized at a minimum of 200% of the RMS load current. 2126 — Bussmann series HEZ breakaway and non-breakaway in-line rejection fuse holders for UL Class CC fuses Technical Data 2127 Effective January 2016 Non-breakaway catalog number system To order: Lineside terminal HEZ Loadside terminal Catalog symbol HEZ - A A A A Specify catalog symbol HEZ and the loadside terminal code.
