Key Features

Class T Current-Limiting Design

Class T current-limiting construction helps limit let-through energy during short-circuit events for downstream equipment protection.

200 kAIC Interrupt Rating

Rated for 200 kAIC at 600 Vac, suitable for large-capacity electrical systems requiring high short-circuit current protection.

Very Fast-Acting Performance

The JJS series is classified as very fast-acting, providing rapid response to overcurrent conditions in sensitive circuits.

Bolted Blade Terminals

Bolted blade end connections on both ends provide secure electrical contact in compatible fuse holders and mounting configurations.

Non-Indicating Body

Non-indicating design without a visual blown-fuse indicator, suited for installations where remote or indirect monitoring is used.

Compact Footprint

Eaton identifies the JJS series as having a small footprint, supporting space-efficient panel layouts in industrial enclosures.

Applications

VFD line protection
Motor branch circuit protection
Industrial control panels
Distribution equipment with high available fault current
Transformer protection in industrial facilities
General-purpose branch circuit protection requiring Class T fuses
Large-capacity electrical systems needing 200 kAIC interrupting rating
