Overview

The Mersen NH Fuse-Base, SKU Q226725, is a robust 3-pole unit designed for high-voltage DC applications, rated for 1000VDC and 250A. This specific model features indirect touch protection, ensuring enhanced safety with an IP20 rating. It is engineered for DIN rail installation, facilitating quick and secure mounting in control panels and electrical enclosures. The base is constructed with a stable, single-part plastic body, housing silver-plated contact springs made from electrolytic copper. These springs are formed from a single piece and are designed for high resilience, utilizing captive steel springs to withstand significant thermal stress, ensuring reliable contact performance even under demanding conditions. This NH fuse-base is compatible with Mersen NH1XL and gPV fuse-links with blade contacts, specifically those rated up to 250A. It is supplied with two phase-partition walls, crucial for maintaining separation in a multi-pole configuration. For added safety and convenience, plug-on covers for the contact springs are also available. The design prioritizes user safety, offering indirect touch protection, which means a microswitch cannot be fitted to this particular model. The rated impulse withstand voltage (Uimp) for this series is 6kV for size 00 and 8kV for sizes 0-4, underscoring its capability to handle transient overvoltages. Manufactured in the US, this Mersen fuse-base (Q226725) is a reliable component for DC power distribution and protection systems where safety and performance are paramount.
