Overview
The Edison ECSR10 10A 600V is a Class RK5 time-delay dual-element current-limiting fuse designed for AC power distribution systems. This lot includes 3 units of the ECSR10, ideal for facilities requiring motor overload, ground fault, and short-circuit protection in feeder, branch, and mains circuits.
Key Features
- Class RK5 current-limiting fuse with superior overload and cycling capabilities
- Dual-element, time-delay design—10 second delay at 500% of rating
- Ferrule-end construction for secure holder mounting
- 200 kAIC (kiloampere interrupting capacity) rating
- Sized for motor and transformer loads with minimal nuisance trips
- Compliant with industry standards for AC distribution protection

Typical Applications
The ECSR10 is recommended for AC power distribution systems protecting circuits with:
- Inductive loads: Motors, transformers, and compressors—where inrush current may exceed steady-state amperage
- Non-inductive loads: Lighting, heating, and resistive equipment
- Feeder and mains protection: Primary and secondary distribution circuits rated up to 600 VAC
- Short-circuit current capacity: Systems rated to 200 kA RMS symmetrical amperes (200,000 A)
The time-delay characteristic allows the fuse to coordinate with motor soft starters and allows temporary surge currents without nuisance openings, reducing downtime and replacement costs.
