JTD040-ID - 40 Amp Fuse

JTD040-ID - 40 Amp Fuse

When you need an indicating 40A Class J time-delay fuse, the details matter well beyond the amperage printed on the fuse. The JTD040-ID—identified by the manufacturer as JTD040ID—is a 40-amp Class J industrial cartridge fuse with Slo-Blo/Time Lag (T)/Time Delay operation and an indicating design. It is rated for a maximum of 600VAC and 300VDC and belongs to the JTD_ID Series and POWR-PRO Fuse family. For anyone replacing an existing fuse, matching the 40A rating is only one part of the job. Equipment requirements should also match the Class J designation, time-delay opening characteristic, indicating configuration, voltage and interrupting requirements, cartridge construction, and mounting arrangement.

Key Features and Benefits

• 40A continuous current rating for equipment specifically requiring a 40-amp fuse
• Class J fuse configuration for compatible Class J equipment
• Time-delay operation specified as Slo-Blo/Time Lag (T)/Time Delay
• Indicating design helps distinguish the JTD040-ID from the non-indicating JTD040 configuration
• Rated for a maximum of 600VAC
• Supports a maximum of 300VDC
• Industrial cartridge construction
• Identified within the POWR-PRO Fuse family
• Designed for installation using a compatible fuse block, clip, or holder
• LFPSJ60 Series is specified as the corresponding holder family

Material Compliance and Certifications

The supplied information establishes the JTD040-ID's 40A continuous current rating, Class J classification, time-delay opening characteristic, 600VAC and 300VDC maximum ratings, industrial cartridge construction, indicating design, interrupting values, and mounting information.

Where It Works Best

The JTD040-ID 40A Class J indicating fuse suits electrical equipment designed for a 40A Class J time-delay fuse with an indicating configuration and corresponding electrical and physical requirements. For AC service, compare the equipment requirements with the fuse's 600VAC maximum rating and the applicable AC interrupting value. For DC service, the supplied specifications state a 300VDC maximum rating with a 20 kA interrupting rating at 300VDC.
