Overview

The Mersen V229121 NH00 3-pole fuse base is a high-reliability industrial component designed for low-voltage fuse systems up to 160A. Rated for 1000VAC and 1000VDC, this fuse base is engineered for demanding electrical distribution applications where precise fault protection is critical. The three-pole design supports parallel mounting in compact configurations, with phase-partition walls included for enhanced safety and isolation between poles. Constructed with a durable plastic base and silver-plated electrolytic copper contact springs, the V229121 ensures low-resistance electrical connections and high thermal stability under continuous operation. The captive steel springs provide independent springing action, making the contacts resilient to thermal stress and mechanical wear. Compatible with NH fuse-links featuring 8mm contact blades, this fuse base is ideal for industrial panels, motor control centers, and power distribution units. The DIN rail mount design simplifies installation and maintenance, while the EP (square contact) type ensures secure connections with standard NH fuse-links. With a rated impulse withstand voltage of 6kV (size 00), the V229121 meets stringent IEC standards for electrical safety and reliability.
