Information About TR400R
The TR400R is part of the Mersen Ferraz Shawmut Tri-Onic TR-R fuse family, developed to meet industry requirements for dependable time-delay overcurrent protection. Its RK5 classification allows the fuse to accommodate motor starting currents while maintaining effective protection against sustained overloads and short circuits. The fuse is commonly used in motor control centers, distribution panels, service entrances, and industrial power systems where selective coordination and current limitation are required.
Key Features:
- RK5 Fuse Classification: Provides standardized protection for low-voltage power distribution systems.
- Time-Delay Operation: Allows temporary inrush currents during motor startup without nuisance blowing.
- Current-Limiting Design: Reduces peak let-through energy during fault conditions.
- 400 Amp Rating: Suitable for high-current industrial and commercial applications.
- Tri-Onic TR-R Series: Designed for motors, transformers, feeders, and branch circuits.
- Dual Voltage Rating: Rated for 250 VAC and 160 VDC applications.
- Industry-Standard Construction: Compatible with common fuse holders and disconnect equipment.
The TR400R delivers the reliability and precision required for effective motor and feeder circuit protection in industrial and commercial electrical systems.
