£447.38
The Mersen M200D03 is a robust 200 A three-pole fuse switch disconnector designed for switching, isolation and overcurrent protection within low-voltage electrical distribution systems. Developed for use with NH Size 0 fuse links, it combines dependable load-break switching with replaceable fuse protection in one compact assembly.
Featuring a 0+3 pole configuration and front-operated mechanism, the M200D03 is well suited to installation in industrial switchboards, power distribution panels and motor control centres. Its design allows all three phase conductors to be switched simultaneously, providing a clearly defined means of circuit isolation for inspection, maintenance and equipment servicing.
With a rated current of 200 A, the Mersen M200D03 is suitable for protecting industrial feeders, machinery supplies and other substantial three-phase loads. When fitted with correctly selected NH fuse links, it helps protect cables and downstream equipment against overload and short-circuit conditions.
Fuse switch disconnectors provide a practical combination of load switching and overcurrent protection. The Mersen M200D03 allows electrical circuits to be manually disconnected while its NH fuse links provide protection against excessive current and short-circuit faults.
The fuse links should be selected according to the conductor size, load characteristics, prospective fault current and required utilisation category. This flexibility allows the M200D03 to be configured for a wide range of industrial power distribution and machinery applications.

The M200D03 is used to switch, isolate and protect three-phase low-voltage circuits in industrial switchboards, distribution panels and machinery installations.
The Mersen M200D03 is designed for NH Size 0 fuse links. The required fuse rating and operating class should be selected according to the protected circuit.
The Mersen M200D03 has a nominal current rating of 200 A.
The 0+3 configuration means that the device has three switched phase poles and no additional switched neutral pole.
Fuse links are generally selected separately so their current rating, breaking capacity and utilisation category can be matched to the electrical installation.
Mersen fuse switch disconnectors are widely specified by panel builders, electrical contractors and industrial engineers for dependable circuit isolation, effective fuse protection and reliable operation in demanding low-voltage distribution systems.
