Overview

The Mersen D200793 NH fuse-base is a high-reliability, 2-pole plastic fuse-base designed for industrial electrical protection systems. Rated for 1000VAC and 1000VDC at 160A, this EP-type fuse-base features square contacts and clamp screw connections for secure, high-current terminations. The unit supports conductor cross-sections from 1.5 to 25 mm², making it suitable for heavy-duty applications in power distribution, motor control centers, and industrial switchgear. Constructed with silver-plated electrolytic copper contact springs and resilient captive steel springs, the D200793 ensures stable, low-resistance connections even under high thermal stress. The design includes indirect touch protection, eliminating the need for microswitches in safety-critical installations. With a power acceptance of 12W and a rated impulse withstand voltage of 6kV (8kV for sizes 0-4), this fuse-base meets IEC standards for robust electrical protection. Compatible with NH fuse-links, the D200793 supports parallel mounting in compact configurations, optimizing panel space. The plastic base construction ensures lightweight durability, while the clamp screw terminals provide tool-free conductor adjustment and secure clamping. Ideal for OEMs, panel builders, and maintenance teams requiring reliable, high-current fuse protection in industrial environments.
