Mersen M63D03 63 A three-pole fused switch disconnector for DIN size 000 fuse links, designed for industrial circuit switching, isolation and overcurrent protection.
£288.20
The Mersen M63D03 is a compact fused switch disconnector designed to provide dependable load switching, secure electrical isolation and fuse-based circuit protection in industrial low-voltage installations. With a rated current of 63 A, it is suitable for machinery, control panels and power distribution systems requiring reliable protection and safe maintenance isolation.
By combining a manually operated switching mechanism with compatible fuse links, the M63D03 provides both circuit isolation and overcurrent protection within one assembly. This integrated arrangement can simplify electrical panel design while helping protect cables, machinery and downstream equipment against overload and short-circuit currents.
The Mersen M63D03 features a three-pole configuration, an 0+3 operating arrangement and compatibility with DIN size 000 fuse links. Its compact design makes it a practical choice for panel builders, OEMs and electrical engineers working with three-phase industrial equipment and low-voltage distribution systems.
Fused switch disconnectors combine a manual isolation switch with replaceable fuse links. This arrangement allows electrical circuits to be disconnected before maintenance while also helping protect connected cables and equipment against excessive current during normal operation.
The Mersen M63D03 switches all three phases together, establishing a clearly defined isolation point for machinery and electrical equipment. Correctly rated DIN size 000 fuse links should be selected according to the load, conductor size and protection requirements of the installation.
