FRS-R-175 - 175Amp Fuse

FRS-R-175 - 175Amp Fuse

The FRS‑R‑175 fuse from Eaton/Bussmann delivers high‑performance over‑current protection for industrial electrical systems that demand both reliability and durability. With a 175 amp rating and support for up to 600 V AC or 300 V DC, this dual‑element, time‑delay Class RK5 fuse is engineered to handle heavy inrush currents—such as those produced by motors and transformers—without nuisance tripping. The non‑indicating design means fewer moving parts and less likelihood of visual indicator failure, while the current‑limiting capability offers enhanced protection for downstream equipment in fault conditions.

Key Features and Benefits

• Time‑delay, dual‑element construction: Designed to stay closed through start‑up surges and inrush loads—so motors and control circuits aren’t interrupted prematurely.
• Built‑in current‑limiting action: Reduces the energy let‑through during short‑circuit events, protecting sensitive downstream equipment and connections.
• Compact, industry‑friendly form: Fits standard Class RK5 holders and blade‑end connections for easy installation, replacement, and maintenance.
• High interrupting capacity: Provides strong fault‑clearing capability—increasing system safety and resilience in demanding industrial environments.
• Non‑indicating fuse version: Simplifies the product footprint by eliminating a visual “blow” indicator, reducing exposed parts and potential failures.
