Overview
The ECSR60 600V 60A is a Class RK5 dual-element, time-delay fuse engineered for AC power distribution systems. This industrial-grade fuse combines current-limiting and time-delay capabilities, making it suitable for protecting AC mains, feeders, and branch circuits in facilities with motors, transformers, and other inductive or non-inductive loads.
Key Features
- Dual-Element Design: Combines dual-element current limiting and time-delay capabilities for 600V systems up to 60A
- Time-Delay Protection: Dual element, time-delay fuses have minimum industry standard time-delay of 10 seconds at 5 times the fuse rating
- Overcurrent Management: Time-delay characteristics typically allow sizing closer to running ampacity of inductive loads to reduce cost and provide improved overcurrent protection
- Ferrule-End Connections: Standard ferrule-end termination for secure fitting in Class RK5 fuse holders
- High Interrupting Rating: Available in 600Vac, with 200kA RMS Sym interrupting ratings

Typical Applications
These fuses are recommended for AC power distribution system mains, feeders and branch circuits having inductive loads (motors, transformers) or non-inductive loads (lighting, heating) where the available short-circuit current does not exceed 200,000 RMS symmetrical amperes. The ECSR60 is widely deployed in industrial facilities, commercial buildings, motor control centers, transformer protection, and general AC distribution systems where load surges and overload cycling are common.
