Features of Class T Fuse

•Fast-Acting (Fast-Blow) Response – Provides instantaneous opening under overcurrent conditions, minimizing damage to sensitive equipment.

•Current Limiting Design – Reduces peak fault current and thermal/magnetic stress on downstream components.

•High Interruption Rating – Capable of safely clearing high fault currents in DC circuits.

•Wide Current Range – Available from 100A to 500A (100A, 200A, 225A, 300A, 350A, 400A, 500A) to match diverse system requirements.

•125V DC Rating – Specifically engineered for low-voltage DC power systems.

•Compact Class T Form Factor – Smaller than equivalent Class R or Class J fuses, enabling space-efficient installations.

•Reliable Performance – Suitable for continuous duty cycles in demanding environments.

Application of Class T Fuse

•Battery energy storage systems (BESS)

•DC power distribution units (PDU)

•Uninterruptible power supplies (UPS) – DC links

•Inverters and rectifiers – DC input protection

•Industrial DC control panels

•Telecom power systems

•Electric vehicle (EV) charging infrastructure – DC side

•Renewable energy systems (solar PV DC combiner boxes, wind turbine DC protection)
