£254.90
The ABB ZLBM2-3P-M12, product code 1SEP620012R3000, is a robust three-pole vertical fuse switch disconnector designed for switching, isolation and fuse protection in low-voltage power distribution systems. As part of the proven ABB InLine II range, it is suitable for industrial switchboards, distribution panels and infrastructure applications requiring reliable high-current circuit protection.
This fuse switch disconnector combines manual load switching with safe circuit isolation and protection through compatible NH fuse links. Its vertical construction supports space-efficient switchboard layouts, while the bolted terminal arrangement provides secure electrical connections for demanding industrial installations.
With a rated current of 400 A, a three-pole configuration and compatibility with DIN NH Size 2 fuse links, the ZLBM2-3P-M12 is suitable for three-phase systems operating at up to 1000 V AC. Its 185 mm phase spacing and M12 bolted connections make it ideal for integration into modern low-voltage distribution assemblies.
Fuse switch disconnectors combine load switching, circuit isolation and overcurrent protection in a single assembly. When fitted with correctly rated NH fuse links, the ABB ZLBM2-3P-M12 helps protect cables and electrical equipment against overload and short-circuit conditions while allowing the circuit to be safely isolated for maintenance.
The ABB InLine II range is engineered for efficient installation in low-voltage switchboards. Its vertical arrangement, robust switching mechanism and secure bolted connections make it suitable for demanding applications where operational reliability, safety and efficient use of panel space are essential.
