FRS 4 1/2
|
- Class RK5 current Limiting
- Most popular fuse for motor circuit protection because time delay handles harmless starting and inrush currents
- Application: Motor circuits, mains, feeders, branch circuits, transformers, service entrance equipment and general purpose protection
- Provides motor overload, ground fault and short circuit protection
- helps protect motors against burnout from overloads and single phasing on three phase systems
- Dual-element fuses can be applied in circuits subject to temporary motor overloads and surge currents to provide both high performance short circuit and overload protection
- Overload element provides protection against low level overcurrent of overloads and will hold an overload which is five times greater than the ampere rating of the fuse for a minimum of ten seconds
- Voltage Rating; 600 Volts AC (or less), 300 Volts DC
- Dual-element Time-Delay 10 second (minimum) at 500% rated current
- Interrupt rating; 200,000 amp RMS sym. for AC voltages and 20,000 amp IC for DC voltages
- Ferrule/Cartridge & Knife Blade types
- Moisture resistant fiberglass bodies
