A3T1100 - 1100 Amp Fuse

A3T1100 - 1100 Amp Fuse

The A3T1100 Class T Fuse is made for electrical systems that need fast, dependable protection under heavy loads. With a 1100 amp rating and a 200 kA interrupting capacity at 300VAC, this fuse is designed to react quickly during overloads and short circuits, helping to protect your valuable equipment before damage spreads through the system.

Its very fast-acting, current-limiting design makes it a strong fit for commercial and industrial applications where electrical reliability is important day after day. The knife-blade style construction provides a solid connection, while the compact Class T body helps you save space inside crowded electrical panels and distribution equipment. In high-demand environments, every second counts during a fault condition, and this fuse is built to respond with speed.

The A3T1100 is often used in power distribution equipment, switchboards, motor control centers, and other high-capacity systems where dependable overcurrent protection is required. It’s a practical solution for protecting sensitive downstream components and helping reduce unnecessary downtime in busy facilities.
