TJS125 - 125Amp Fuse

TJS125 - 125 Amp Fuse

The TJS125 Class T Fuse is built for applications where fast, dependable circuit protection is critical. Rated at 125 amps with a 200 kA interrupting capacity at 600VAC, this fuse is designed for you to react quickly during overloads and short circuits, helping reduce potential damage to connected electrical equipment. Its very fast-acting, current-limiting design makes it a practical choice for protecting sensitive components in commercial and industrial power systems. The knife-blade construction provides a secure fit and efficient installation, while the compact size allows it to work well in tighter electrical assemblies and distribution equipment.

In demanding environments, the TJS125 helps support safer system operation by limiting fault energy before it can spread through the circuit. Whether installed in switchboards, control panels, motor control centers, or other high-performance electrical systems, this Class T fuse offers the level of protection electricians, contractors, and maintenance professionals rely on every day.
