JTD175 - 175 Amp Fuse

JTD175 - 175 Amp Fuse

The JTD175 is a 175A Class J time-delay fuse built around a specific combination of electrical ratings and knife-blade construction. Part of the JTD Series and identified as a POWR-PRO Fuse, it carries a 175A continuous current rating with a Slo-Blo/Time Lag (T)/Time Delay opening characteristic. Maximum voltage ratings are 600VAC and 500VDC. If you're matching a JTD175 for existing equipment, the 175A rating is only the starting point. Fuse class, time-delay characteristic, AC/DC voltage, interrupting requirements, physical construction, and non-indicating design should match the equipment specification.

Material Compliance and Certifications

The supplied product information confirms the JTD175's Class J designation, 175A continuous current rating, time-delay opening characteristic, voltage ratings, interrupting values, knife-blade construction, non-indicating configuration, and mounting method.

Where It Works Best

The JTD175 suits electrical equipment designed for a 175A Class J, time-delay, non-indicating knife-blade fuse with matching electrical and physical requirements. For AC service, verify the equipment specification against the 600VAC maximum voltage and the applicable supplied AC interrupting value. For DC service, confirm the 500VDC maximum voltage and 20 kA interrupting rating at 500VDC.
