Bussmann Fusetron FRS-R-30 Dual-Element Time-Delay Fuse
The Bussmann Fusetron FRS-R-30 is a 30-amp, 600 VAC/300 VDC, dual-element, time-delay fuse designed to provide superior protection for circuits subject to temporary motor overloads and surge currents. Its advanced features make it an ideal choice for various industrial applications.
Key Features
- Dual-Element Design: Offers both high-performance short-circuit and overload protection, ensuring reliable operation in demanding environments.
- Time-Delay Capability: Provides a 10-second delay at 500% of the rated current, allowing the fuse to accommodate temporary inrush currents without unnecessary interruptions.
- Current Limitation: Helps protect downstream components from high fault currents by limiting the amount of energy let through during a fault condition.
- Compact and Cost-Effective: The time-delay feature permits the use of smaller fuse amp ratings, enabling the selection of smaller and more economical switches and panels.
- Motor Protection: Offers backup protection to motors, safeguarding against burnout from overloads and single-phasing on three-phase systems.
