  • Surge Protector 1P | 20 kA | 275 VAC | Class B+C | DIN rail mounted

    Code: G30-B+C/280/12.5-1P

    Surge protection device designed to protect low-voltage electrical systems, industrial control equipment and solar energy installations from lightning and switching overvoltages.

    This SPD is built according to B+C (Type 1+2) class, making it suitable both for primary lightning current discharge and for suppression of smaller transient overvoltages. The device features a modular design for quick cartridge replacement, a clear status indicator (green – operating, red – fault), the option to connect a remote signaling contact, as well as innovative thermal disconnection and arc-insulation technologies ensuring safe and reliable operation.
