TJS1200 - 1200 Amp Fuse

TJS1200 - 1200 Amp Fuse

When your electrical systems are exposed to high fault currents, dependable overcurrent protection becomes critical. The TJS1200 Class T fuse is built for applications that need fast response times and strong current-limiting performance in a compact footprint. Rated at 1200 amps with a 200 kA interrupting capacity at 600VAC, this fuse is commonly used in commercial and industrial power distribution systems where equipment protection and uptime matter.

Its very fast-acting design helps clear short circuits quickly, reducing the chance of damage to sensitive electrical components and connected equipment. The knife-blade style construction allows for secure installation, while the non-indicating design keeps maintenance straightforward for facilities already following routine inspection schedules. Because it’s compact for its class, the TJS1200 can also help simplify installations where panel space is limited.

Whether protecting switchboards, motor control systems, or heavy-duty electrical equipment, the TJS1200 provides reliable performance in demanding environments without taking up unnecessary space.
