The Eaton 170M3809D is a high-quality, centred tag blade fuse engineered for safe and efficient overcurrent protection in electrical installations and automation systems. Featuring a 50A current rating and 690V AC voltage rating, it is designed for use in demanding industrial environments where reliable protection of sensitive equipment and semiconductors is critical.
This NH1 size fuse utilizes a blade/tag connection with a 20mm tag width, ensuring secure placement in fuse holders or distribution boards. Its fast acting ('aR' application category) characteristic makes it especially suited for the protection of power semiconductors such as diodes, thyristors, and variable speed drives, rapidly disconnecting circuits during fault conditions to minimize equipment damage.
The product incorporates a high rupture capacity, enabling safe interruption of high fault currents without endangering the installation. A dual indicator system improves maintenance and operational safety by providing a visual cue of fuse status. The fuse's compact body, measuring 135mm in overall length, 68mm height, and 40mm width, facilitates integration within standard NH1 panel cutouts.
Complying with rigorous international safety standards including CSA, UL, IEC, and CE, this fuse supports global deployment in industrial, commercial, and automation settings. Typical use cases include utility panels, motor control centers, power conversion, and heavy-duty industrial process equipment where rapid fault protection for electronic components is required.
The Eaton 170M3809D offers durable construction, enhanced by live gripping lugs for secure handling during installation and replacement. Its high-speed performance, safety features, and robust certification make it a preferred choice for electrical engineers and maintenance professionals.
