Information About TRS400R
The TRS400R is part of Mersen’s Tri-Onic family of current-limiting time-delay fuses intended for demanding electrical protection applications. It features a cylindrical ferrule-style construction with tin-plated copper blade terminals for secure clip mounting. The fuse integrates seamlessly into UL Class RK5 fuse holders used in service entrance, feeder, and motor branch circuits. It is widely used in systems where time-delay characteristics are required to accommodate motor starting currents while still providing strong short-circuit protection.
Key Features:
- Tri-Onic RK5 design: Provides time-delay protection for motors and inductive loads.
- 400 A current rating: Suitable for high-capacity feeder and service circuits.
- 600 V AC/DC rating: Supports a wide range of industrial power systems.
- High interrupting capacity: Rated up to 200 kA for severe fault conditions.
- Current-limiting performance: Reduces peak let-through energy during faults.
- Ferrule blade terminals: Ensures secure clip-mounted installation.
- Non-indicating construction: Designed for standard RK5 fuse applications.
The TRS400R delivers the reliability and precision required for industrial motor, feeder, and service entrance circuit protection.
