Information About TR225R
The TR225R is part of Mersen’s Tri-Onic family of current-limiting fuses developed for demanding electrical protection applications. It features a time-delay design that allows temporary inrush currents, such as motor starting, without compromising protection against sustained overloads and short circuits. The fuse is constructed using advanced materials, including a PolyTube body and tin-plated copper blade terminals, to ensure consistent performance and durability. It is commonly installed in motor circuits, service entrance equipment, feeders, transformers, and general-purpose power distribution systems.
Key Features:
- 225 Amp Rating: Suitable for high-current motor and feeder protection.
- Class RK5 Fuse: Designed for use in standard RK5 fuse holders.
- Time-Delay Characteristic: Allows inrush currents while protecting against overloads.
- High Interrupting Capacity: Rated up to 200 kA for severe fault conditions.
- Current-Limiting Design: Reduces peak let-through energy during short circuits.
- AC/DC Rated: Supports both alternating and direct current applications.
- Blade-Type Terminals: Ensures secure electrical contact in clip-mounted installations.
The TR225R delivers the reliability and precision required for motor circuits, feeders, and industrial power protection systems.
