Model Metrosil - Silicon Carbide Varistors
Metrosil silicon carbide varistors are manufactured by M&I Materials in the UK, and trusted worldwide as surge protection devices that provide excellent service in a wide range of applications. At M&I Materials we have been developing and producing Metrosil for over 80 years and pride ourselves on delivering manufacturing excellence and high standards of technical support. Metrosil is manufactured from a semi-conducting material with the distinctive property that its electrical resistance depends on the applied voltage enabling it to act as an 'electrical safety valve' to protect equipment and insulation from the effects of over voltages. Millions of Metrosil varistors have been sold throughout the world with current ratings varying from microamps to kiloamps and the capability of absorbing energies from 10 to 50,000 joules per disc.
