The PROTEC B2S 12.5 series of over-voltage surge protective devices has been developed to protect against partial direct and indirect lightning discharges and is intended to provide protection in zones 0A - 1, per IEC 62305. PROTEC B2S 25 (2+0) series combines two PROTEC B2S 12.5 modules to provide protection for single phase TNS network. PROTEC B2S 37.5 (3+0) combines three PROTEC B2S 12.5 units, to provide protection for TNC three phase networks with a combined PEN conductor.
