Applications

The FRS-R-9 fuse is suitable for use in combination starters, motor control centers, machinery disconnects, and power panelboards. Its time-delay feature allows it to handle temporary motor overloads and surge currents, providing both high-performance short-circuit and overload protection. This makes it ideal for protecting motors against burnout from overloads and single phasing when sized properly.

Additional Information

The dual-element design of the FRS-R-9 fuse offers superior time-delay performance, allowing for closer sizing and enhanced protection of motors and transformers. This design also permits the use of smaller fuses and less costly switches, leading to potential cost savings. The fuse provides current limitation to help protect downstream components from high fault currents and offers motor running back-up protection without extra cost.

Each box contains nine FRS-R-9 fuses, ensuring you have adequate spares for maintenance and replacements.
