The Mersen B1023248 is a high-performance MULTIVERT® NH vertical fuse switch disconnector engineered for safe switching, isolation and overcurrent protection in demanding industrial low-voltage power distribution systems. Manufactured under catalogue number 1.300.095, this three-pole unit is designed for NH Size 3 fuse links, providing a 630 A current rating and a maximum operating voltage of 690 V AC.
Designed for installation on 185 mm busbar systems, the B1023248 features robust 3 × M12 bolted cable terminations and incorporates a factory-fitted 600/5 A, 5 VA, Class 1 current transformer for triple-pole measurement. This integrated metering capability enables accurate current monitoring without increasing the installation depth, making it ideal for modern industrial switchboards and power monitoring applications.
Part of the proven MULTIVERT® 630 A modular platform, the B1023248 combines compact installation, dependable electrical performance and simplified maintenance, making it suitable for OEM equipment, transformer substations and industrial distribution panels.
NH fuse switch disconnectors provide dependable manual isolation while protecting circuits against overloads and short circuits through NH fuse links. The integrated measuring transformer fitted to the B1023248 enables accurate three-phase current monitoring without requiring additional external mounting space.
The Mersen B1023248 combines high-current switching capability with integrated metering, making it particularly suitable for industrial switchboards, transformer substations, feeder pillars and power distribution systems where both protection and electrical monitoring are required.
