JTD500 - 500 Amp Fuse

JTD500 - 500 Amp Fuse

The JTD500 is a 500A Class J time-delay fuse designed for electrical equipment that requires this combination of amperage, voltage, opening characteristic, and knife-blade construction. Part of the JTD Series and POWR-PRO Fuse family, it carries a 500A continuous current rating, a maximum rating of 600VAC and 500VDC, and Slo-Blo/Time Lag (T)/Time Delay operation. If you're matching a replacement, the 500A rating is only the starting point. Before matching, check the Class J requirement, time-delay characteristic, AC or DC voltage, applicable interrupting rating, non-indicating configuration, blade format, and holder compatibility.

Material Compliance and Certifications

The supplied product information confirms the JTD500's electrical ratings, Class J designation, time-delay opening characteristic, knife-blade construction, non-indicating configuration, mounting method, and specified holder series.

Where It Works Best

The JTD500 suits electrical equipment designed for a 500A Class J time-delay, non-indicating fuse with knife-blade construction and the corresponding electrical requirements. For AC installations, confirm the equipment requirements against the 600VAC maximum rating and the applicable manufacturer-supplied AC interrupting value. For DC service, the supplied specifications identify a 500VDC maximum voltage and 20 kA interrupting rating at 500VDC.
