Introduction

This panel-mount fuse holder features a screw knob and accommodates 13/32×15/16 in. to 1¼ in. fuses. It is UL Listed (Guide IZLT2, File E14853) and CSA Certified (Class 6225-01, File 47235), with a flammability rating of UL 94 HB. Regarding electrical ratings, without CSA certification, the maximum current is 20A using quick-connect terminals; the HPF-C CSA rating is 15A, 250V. Regarding maximum panel thickness, when the mounting flange is on the front of the panel, assuming Pollution Degree 3 per UL 840 (conductive pollution, or dry non-conductive pollution that becomes conductive due to expected condensation), excluding any sealing gasket; a thicker panel may be used if the fuse holder load terminals are fully insulated (using UL-recognized VW-1 rated insulating heat-shrink tubing), or if the intended environment is Pollution Degree 1 or 2, or if the panel is non-conductive. Pollution Degree 2 typically involves non-conductive pollution only, but temporary conductivity may occur due to condensation; Pollution Degree 1 involves no pollution or only dry non-conductive pollution with no influence on insulation. When the mounting flange is on the rear of the panel, the maximum panel thickness is 5.08mm/0.200 in. (flush with the knob collar).
