JTD150 - 150 Amp Fuse

JTD150 - 150 Amp Fuse

The JTD150 is a 150A Class J time-delay fuse built around a specific combination of electrical ratings and knife-blade construction, so choosing it involves more than simply matching the amp number. Part of the JTD Series and identified as a POWR-PRO Fuse, the JTD150 uses a Slo-Blo/Time Lag (T)/Time Delay opening characteristic and carries maximum voltage ratings of 600VAC and 500VDC. When you're matching a replacement fuse, check the complete specification—not just 150A. Fuse class, time-delay operation, voltage, interrupting rating, knife-blade format, non-indicating design, and mounting compatibility all matter.

Material Compliance and Certifications

The supplied product information confirms the JTD150's Class J designation, 150A 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 JTD150 suits electrical equipment designed for a 150A Class J, time-delay, non-indicating knife-blade fuse with matching electrical and physical requirements. For AC service, verify the equipment specifications against the 600VAC maximum rating and the applicable supplied AC interrupting value. For DC service, confirm compatibility with the 500VDC maximum rating and 20 kA interrupting rating at 500VDC.
