Features:
• With our sustained efforts & dedicated management, we have been able to offer qualitative Class C Surge Arrester.
• Protection of heavy-loaded electrical circuits from overload
• Surge protector.
• Used to protect not only particular consumers/circuits, but also the whole panel
• Precisely designed, this surge arrester is generally used in electrical industry.
• On-Off indicating window: Green: normal function; Red: functionless, immediate replacement required.
• Surge arrestor.
• Provided surge arrester is not only manufactured from excellent quality raw material and the latest technology but also properly checked on diverse parameters.
• Din Rail mountable.
Application:
• BR-20 series surge protective devices are suitable for C grade surge protection, which protects the electrical network not shocked by the thunder.
• BR-20 Surge protective Devices (referred as SPD) provide protection against surge current resulted from direct or indirect lightning strike or similar surge voltage.
• The Britec BR-20 series surge protection devices are usually installed in low voltage main distribution box connected to the incoming end of the buildings.
• SPD is applicable to circuit with rated frequency 50/60Hz.
