Overview

The Mersen W219278 is a NH0 plastic fuse base designed for NH fuse-links up to 160A. Rated for 1000VAC and 1000VDC, this 3-pole base provides reliable overcurrent protection in low-voltage systems. It features DIN rail mounting for efficient installation and close spacing in parallel rows, ideal for space-constrained industrial panels. The base includes two phase-partition walls for enhanced safety and isolation between poles. Constructed with a one-piece silver-plated copper contact spring system, it ensures consistent performance under high thermal stress. Separate captive steel springs provide resilience against thermal cycling. The plastic housing offers durability and electrical insulation. For fuse monitoring, a microswitch (sold separately) can be integrated with striker-equipped fuse-links. Rated impulse withstand voltage is 8kV for sizes 0-4. Installation requires M8 screw terminals with recommended tightening torque of 8-10Nm. Package weight is 1.5 kg for the 3-pole configuration.
