JTD225 - 225 Amp Fuse

JTD225 - 225 Amp Fuse

The JTD225 is a 225-amp Class J time-delay fuse in a knife-blade configuration for equipment that requires this specific combination of current rating, fuse class, opening characteristic, and physical format. Part of the JTD Series and identified as a POWR-PRO Fuse, it has maximum voltage ratings of 600VAC and 500VDC and uses a Slo-Blo/Time Lag (T)/Time Delay opening characteristic. If you're replacing an existing 225A fuse, don't stop at the amperage. Confirm the Class J requirement, time-delay characteristic, AC or DC voltage, applicable interrupting requirements, non-indicating configuration, knife-blade construction, and mounting compatibility before determining that JTD225 is the correct match.

Material Compliance and Certifications

The supplied product data confirms the JTD225's 225A rating, Class J designation, time-delay opening characteristic, AC and DC maximum voltage ratings, interrupting values, knife-blade construction, non-indicating configuration, and mounting method.

Where It Works Best

The JTD225 suits electrical equipment designed for a 225A Class J time-delay fuse with matching voltage, interrupting, physical, and mounting requirements. For AC equipment, verify the application against the fuse's 600VAC maximum rating and the applicable supplied AC interrupting value. For DC equipment, compare the required specifications with the 500VDC maximum rating and 20 kA interrupting rating at 500VDC.
