TRS50R – Mersen | 600V 50A 5 1/2×1 1/16 TD

Description

The Mersen TRS50R Tri-Onic® Class RK5 Time-Delay Fuse provides reliable overcurrent and short-circuit protection for heavy-duty industrial circuits, motors, transformers, and service entrance equipment. Engineered with advanced current-limiting capabilities, this 50-ampere ferrule fuse safely handles harmless motor starting currents and transformer inrush surges without nuisance tripping while offering robust protection against severe overloads.

Rated for 600 VAC and 300 VDC with an impressive 200 kA interrupting rating (I.R.), the TRS50R features a durable polytube body and high-conductivity copper terminal connections. Its dual-element design ensures precise time-delay performance, making it an industry standard for motor branch-circuit and feeder protection where high peak currents occur.

Key Features

• Time-Delay Characteristic: Engineered with a dual-element construction to safely absorb harmless motor starting and transformer inrush currents without premature blowing.
• High Interrupting Rating: Delivers superior fault protection up to 200 kA AC breaking capacity to safely clear high-magnitude short circuits.
• 600V AC / 300V DC Rating: Certified for versatile heavy-duty industrial application requirements across both alternating and direct current systems.
• Class RK5 Current-Limiting: Provides exceptional current limitation to minimize thermal and magnetic stress on downstream equipment during fault conditions.
• Robust Ferrule Construction: Features high-grade copper ferrule terminals for secure electrical contact and efficient power transmission.
• Durable Polytube Body: Housed in an insulating polytube material designed for structural integrity and arc containment in demanding electrical environments.
