Why Choose the Mersen BB31PPRFS NH3 Fuse Base?
The Mersen BB31PPRFS is a robust single-pole NH3 plastic fuse base designed to provide secure mounting and dependable electrical connection for compatible NH fuse links. Rated at 630 A, it is suitable for demanding low voltage power distribution systems in industrial, commercial and infrastructure applications.
This fuse base supports operating voltages up to 1250 V AC and 1000 V DC, allowing it to be used across a wide range of AC and DC installations. Its screw connections provide reliable conductor termination, while DIN rail mounting helps simplify installation within suitable switchboards and electrical enclosures.
The BB31PPRFS incorporates IP20 indirect touch protection to help reduce the risk of accidental contact with live components. Stable silver-plated electrolytic copper contact springs and resilient captive steel springs help maintain consistent contact pressure under high thermal and electrical loads.
