The Mersen BB23PP is a heavy-duty three-pole NH2 plastic fuse base designed to provide secure mounting and dependable electrical connection for compatible NH fuse links. Also identified by Mersen item number B212107, it is engineered for high-current industrial power distribution systems requiring reliable overload and short-circuit protection.
Rated at 400 A, the BB23PP supports operating voltages up to 1250 V AC and 1000 V DC. Its high current and voltage ratings make it suitable for demanding electrical distribution, renewable energy, battery storage and power conversion applications.
The three-pole assembly features screw mounting and screw-type conductor connections for a secure installation within switchboards and electrical panels. Stable silver-plated electrolytic copper contact springs provide efficient conductivity, while the supplied phase-partition walls help maintain separation between adjacent fuse positions.
NH fuse systems are widely used to protect electrical feeders, cables, transformers and industrial equipment against damaging overload and short-circuit currents. The Mersen BB23PP provides a stable three-pole platform for compatible NH2 fuse links, helping maintain the electrical contact pressure required for dependable fuse operation.
The three-pole construction allows all three phases of an electrical supply to be protected within one coordinated assembly. Its high AC and DC voltage ratings make it suitable for both conventional industrial power systems and modern renewable energy or battery-based installations.
