Metrosil offers a wide range of products designed to provide surge protection for large-scale electrical equipment.
Our versatile products are relied upon by leading organisations globally in a variety of applications from protection of generator excitation systems, through to current transformer protection and relay protection.
Metrosil products can be supplied as plain unmounted discs or mounted on central studs, either as single discs or as multidisc assemblies arranged in series or parallel. The smaller size can be supplied with wire terminations and encapsulated in pvc or epoxy.
Metrosil units can handle a broad range of electrical current from microamps to kiloamps, and absorb high amounts of energy. With more than 80 years’ experience in delivering overvoltage protection, we can manufacture a wide range of varistors to meet specific customer requirements.
Metrosil products are manufactured by M&I Materials at its headquarters in Manchester, UK. M&I Materials grew out of the research division of GEC Alstom and became an independently owned business in 1993.
M&I Materials is proud of the wide range of company and product awards, approvals and certifications that we have worked hard to achieve and maintain. Together, they assure you of the pedigree of our company, systems and products and demonstrate our commitment to achieving the highest standards.
