The pluggable compact surge protectors Type 2 or Type 3 DACC, are designed to protect electrical installation at the main switchboard or at secondary panels.. Their compact format allow to install it in limited space. This SPD is based on high energy varistor equipped with thermal disconnector and failure indicator, to comply with standards. guaranteeing a maximum protection efficiency, an high impulse current capability and a improved reliability. DACC surge protectors are available in 2 impulse current versions (DAC15C et DAC40C), in multipolar configuration and in several operating voltages to protect all kind of single or 3-phase AC networks
