Why Choose the Mersen T1023195 MULTIVERT® NH Fuse Switch Disconnector?

The Mersen T1023195 is a high-performance MULTIVERT® NH vertical fuse switch disconnector designed to provide dependable switching, isolation and fuse protection within industrial low-voltage distribution systems. Rated at 250 A, this Size 1 unit is engineered for direct installation onto 185 mm busbar systems.

As part of the proven Mersen MULTIVERT® 250A series, the T1023195 features a three-pole switching arrangement and an integrated current transformer for three-phase electrical measurement. Its modular construction supports fast installation, straightforward maintenance and a high level of protection for personnel working around the equipment.

With a rated operational voltage of up to 690 V AC, secure M10 screw terminals and an integrated 200/5 A current transformer, the T1023195 is well suited to distribution switchboards, feeder pillars, metering systems and industrial power control installations requiring reliable circuit isolation and current monitoring.
