Mersen H212021 single-pole DIII screw-mounted fuse base, catalogue reference 00072.400000, rated at 63 A and 500 V AC/DC with ceramic construction and no integrated touch protection.
The Mersen H212021, catalogue reference 00072.400000, is a durable single-pole DIII fuse base designed for use with compatible D-system screw fuse links. It provides a secure mounting and electrical connection point for low-voltage circuit protection within distribution boards, fuse boxes and industrial electrical installations.
This model features a traditional open fuse-base design without integrated touch protection. Its high-strength ceramic construction provides dependable electrical insulation and resistance to thermal stress, making it suitable for established D-system installations where robust and reliable fuse mounting is required.
Rated at 63 A and 500 V AC/DC, the H212021 is suitable for protecting cables, conductors and electrical distribution circuits when fitted with the correct DIII fuse link and associated gauge component. Its screw-mounted format provides a secure installation within compatible electrical enclosures.
D-system fuse bases provide the mechanical support and electrical connection required for replaceable screw fuse links. When an overload or short circuit occurs, a correctly rated DIII fuse link interrupts the current to help protect cables, power lines and connected electrical equipment.
The Mersen H212021 is particularly suited to maintenance and replacement work involving established DIII fuse assemblies. Its ceramic construction and screw-mounted design provide dependable service in industrial, commercial and utility distribution equipment.
