The PROTEC B2S(R) 12.5 is a part of PROTEC series of over-voltage surge protective devices that have been developed to protect against partial direct and indirect lightning discharges and are intended to provide protection in zones 0A - 1 as per IEC 62305.The circuit topology consists of two varistor stages each protected by a thermal disconnection device. Each unit comprises two high performance varistor blocks. A unique indicator monitors all disconnectors and brings up a common status flag if any one stage should fail, while the plug-in module / base design facilitates replacement of a failed module without the need to remove system wiring etc.
