JTD200 - 200 Amp Fuse

JTD200 - 200 Amp Fuse

A 200-amp rating may be the first thing you check when replacing a fuse, but it shouldn't be the last. The JTD200 is a 200A Class J time-delay fuse with knife-blade construction, a maximum rating of 600VAC and 500VDC, and a Slo-Blo/Time Lag (T)/Time Delay opening characteristic. When checking a replacement or matching a fuse to existing equipment, compare the full specification: amperage, Class J configuration, time-delay characteristic, voltage ratings, interrupting requirements, knife-blade format, and holder compatibility.

Material Compliance and Certifications

The supplied product information confirms the JTD200's Class J designation, 200A 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 JTD200 suits electrical equipment designed for a 200A Class J time-delay fuse with knife-blade construction and corresponding electrical requirements. For AC service, verify the equipment specification against the fuse's 600VAC maximum voltage and the applicable supplied AC interrupting value. For DC service, confirm compatibility with the 500VDC maximum rating and 20 kA interrupting rating at 500VDC.
