Overview
The Gould Shawmut TRS60R is a Tri-Onic current-limiting time-delay fuse designed for overcurrent protection in industrial motor circuits, transformers, service entrance equipment, feeders, and branch circuits. Ferraz Shawmut Tri-Onic® TRS-R current limiting time delay fuses are engineered for over current protection of motors, transformers, service entrance equipment, feeders and branch circuits. The TRS60R combines dual-element construction with time-delay characteristics to safely handle inrush currents without nuisance clearing.
Key Features
- Time-Delay Technology: The time-delay characteristics of the TRS-R safely handle harmless starting currents and inrush currents associated with today’s motors and transformers.
- Current Limiting: Reduces fault currents and protects downstream equipment
- Dual-Element Design: Dual-Element Time-Delay Fuse construction for reliable protection
- Class RK5 Rated: UL Class RK5, AIC Rating: 200kA @ 600V
- Multiple Applications: Ideal for Motor Circuits, Mains, Feeders, Brand Circuits, Transformers, Service Entrsance Equipment, General-Purpose Equipment.

Typical Applications
The TRS60R fuse excels in demanding industrial environments. Its time-delay characteristic makes it ideal for motor soft-start scenarios where inrush currents are normal. Common applications include:
- AC induction motor circuits (5–15 hp range)
- Transformer primary protection
- Feeder and service entrance circuits
- General-purpose industrial equipment (pumps, compressors, fans)
- Branch circuits in manufacturing facilities
