TJS350 - 350Amp Fuse

TJS350 - 350 Amp Fuse

The TJS350 Class T Fuse is built for your electrical systems that demand fast response and dependable protection under heavy load conditions. With a 350 amp rating and a 200 kA interrupting capacity at 600 VAC, this fuse is designed to quickly clear dangerous fault currents before they can damage valuable equipment. Its very fast-acting design makes it a strong choice for protecting sensitive components and high-performance electrical systems where even a brief overload can create expensive problems. The knife-blade construction provides a solid connection and helps simplify installation in compatible fuse holders and distribution equipment.

Because it’s a current-limiting Class T fuse, the TJS350 helps reduce the amount of energy that passes through during a fault event. That added protection can help extend the life of connected equipment and improve overall system safety. Its compact size also makes it practical for tighter electrical enclosures where space is limited but reliable overcurrent protection is still critical.
