Why Choose the Mersen X1023129 MULTIVERT® Fuse Switch Disconnector?

The Mersen X1023129 is a compact and dependable NH vertical fuse switch disconnector designed for safe switching, circuit isolation and overcurrent protection in low-voltage electrical distribution systems. Part of the proven Mersen MULTIVERT® 160 A series, it is engineered for direct installation onto 100 mm busbar systems.

The X1023129 combines a modular design with a 1 × 3-pole switching configuration, allowing all three phases to be switched together. Its symmetrical construction supports top or bottom cable connections, while the strap-clamp terminals help simplify installation within switchboards, feeder pillars and electrical distribution cabinets.

Rated at 160 A and 690 V AC, the X1023129 accepts NH Size 00 fuse-links manufactured in accordance with IEC/EN 60269-2 and VDE 0636-2. Its robust construction, high short-circuit ratings and compact 50 mm width make it a reliable solution for industrial, commercial and residential power distribution applications.
