Surge Protector T2 (C) for PV Systems ETITEC M T2 PV 1100/20 Y 002440515

ETITEC M T2 PV 1100/20 Y is a modular type 2 surge protector designed to protect photovoltaic systems (string/inverter). The device is designed for DIN rail mounting (3 TE module) and provides protection for the positive/negative poles relative to the protective conductor and between the poles. The plug-in design allows for easy replacement of cartridges.

Manufacturer: ETI (ETITEC series). ETI provides specialized surge protection solutions and is the author of the ETITEC series designed for PV installations. ETITEC devices meet international standards classified as EN 50539-11 (according to manufacturer markings) and offer versions with optical status indicators and optional remote signaling contacts (RC).
