Overview

The Mersen SKU S210328 is a robust, unipolar fuse base designed for DIN high voltage fuse-links, manufactured in France. This base is engineered to accommodate fuse-links with a 45mm diameter and offers compatibility with multiple lengths: 192mm, 292mm, 367mm, 442mm, and 537mm. It features an integrated indicating device that enables electrical actuation of the opening mechanism or triggers a visual indicator upon fuse melting, provided the fuse is equipped with a trip-indicator. This functionality enhances operational flexibility and safety in electrical systems. The design allows for mechanical system integration and supports the incorporation of microswitch units, adaptable to specific equipment configurations. Constructed for reliable performance in demanding electrical applications, this fuse base ensures high dielectric strength and IP2X protection (standard or optional depending on model). It is suitable for protecting motor feeders and industrial cabinets against overloads and short-circuits, leveraging the high breaking capacity of compatible fuses (up to 100 kA rms). The base supports various mounting options, including DIN rail or back plate mounting, depending on the specific model variant. Electrical connections are made via M10x30 screws in plated steel (minimum 8-8 class), with a maximum recommended tightening torque of 44 Nm. Fixing of the base itself requires M8 screws (not supplied) with a tightening torque of 10 ± 2 Nm. This product is a key component for ensuring safe and efficient fuse protection in industrial settings.
