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.

• In case of surge current or voltage caused by lightning strike or similar, SPD functions quickly to conduct the surge voltage/current to earth and thus effectively prevent the downstream equipment of its protected line from destruction. SPD resume its high electricity resistance to secure normal operation of the protected power network without presence of the surge voltage.
