Key Features

Time-Delay Performance

Provides a minimum 10-second time delay at 500% of rated current, allowing temporary overloads and transient surges to be tolerated without nuisance opening.

Dual-Element Construction

Utilizes two separate elements to handle high in-rush currents and provide overload protection within a single fuse body.

Current-Limiting Design

Limits let-through current under short-circuit conditions to help reduce equipment damage and improve protection coordination.

High Interrupt Rating

Rated 300 kA at 600 Vac and 100 kA at 300 Vdc for application on systems with high available fault currents.

Class J Rejection Feature

Class J dimensions prevent substitution with fuses of lower voltage or interrupting ratings, supporting correct replacement practices.

Non-Indicating, Ferrule Ends

Non-indicating cylindrical body with ferrule end connections for use in compatible Class J fuse holders and blocks.

Applications

Motor branch circuit protection
Motor control center protection
Industrial control panel feeders
Transformer primary protection
HVAC equipment branch circuits
Pump and compressor circuits
General-purpose branch circuit protection
Facilities with high available fault current
