TJS250 - 250Amp Fuse Description
TJS250 - 250 Amp Fuse
The TJS250 Class T fuse is built for your electrical systems that need fast, dependable protection against high fault currents. Rated at 250 amps with a 200 kA interrupting capacity at 600VAC, this very fast-acting current-limiting fuse is commonly used in commercial and industrial applications where protecting sensitive equipment is a priority. Its knife-blade design provides a secure fit and reliable electrical contact, while its compact size simplifies installation in tight spaces within switchboards, control panels, and distribution equipment. Because it reacts quickly during fault conditions, the TJS250 can help reduce damage to downstream components and minimize costly downtime. The non-indicating design keeps the construction simple and practical for a wide range of power distribution setups.
