Why Choose the Mersen BB41P NH4 Fuse Base?
The Mersen BB41P is a heavy-duty single-pole NH4 plastic fuse base designed for the safe installation of compatible NH4 fuse links in high-current low voltage power distribution systems. Rated at 1250 A, it is engineered for demanding industrial, utility and infrastructure applications where reliable overcurrent protection is essential.
As part of the proven Mersen NH Plastic Bases range, the BB41P supports operating voltages up to 1000 V AC and 1000 V DC. Unlike smaller NH fuse bases, the NH4 design incorporates a robust metal baseplate with twin ceramic contact supports, providing outstanding mechanical strength and thermal performance for high-current installations.
Silver-plated electrolytic copper contact springs and separate captive steel springs maintain consistent contact pressure even under severe thermal loading. The BB41P is designed for NH4 fuse links with 8 mm contact blades and offers dependable long-term performance in critical electrical distribution systems.
