Overview

The Mersen S218240 is a single-pole NH00 plastic fuse base designed for NH fuse-links up to 160A, rated for 1000VAC and 1000VDC. Engineered for industrial low-voltage fuse systems, this unit provides reliable electrical protection in demanding applications. The compact plastic base is optimized for DIN rail mounting, enabling quick installation in control panels and electrical enclosures. Key features include indirect touch protection with an IP20 rating, preventing accidental contact with live components. The silver-plated contact springs are made from electrolytic copper, formed from a single piece for superior conductivity and thermal resilience. Separate springing is provided by highly resilient captive steel springs, ensuring contact integrity under extreme temperature fluctuations. The S218240 is specifically designed for size NH00 fuse-links and supports dual cable-connection systems via screw or clamp terminals. Optional clip-on covers for contact springs enhance protection against active parts. The fuse base complies with IEC 60269 and DIN 43620 standards, with a rated impulse withstand voltage (Uimp) of 6kV. This product is part of Mersen's NH plastic fuse-base series, available in single-pole and multi-pole configurations for flexible system integration.
