£108.18
The Lovato SG22PA300R is a robust Type 2 surge protection device (SPD) designed to protect low-voltage AC electrical installations against transient overvoltages caused by indirect lightning strikes and switching operations. As part of the dependable Lovato SG2 surge protection range, it helps safeguard electrical distribution systems, industrial equipment and sensitive electronic devices from costly surge damage.
Designed for 230 V AC power systems, the SG22PA300R features a 2-pole configuration, a plug-in replaceable protection cartridge and an integrated remote signalling contact for continuous status monitoring. Its compact DIN rail mounted design allows fast installation and simple maintenance within electrical distribution boards and industrial control panels.
With a 20 kA nominal discharge current (In) and a 50 kA maximum discharge current (Imax) per pole, the SG22PA300R delivers reliable surge protection while complying with IEC/EN 61643-11, making it suitable for commercial, industrial and photovoltaic installations.
Electrical surges can damage sensitive equipment, reduce component lifespan and lead to costly downtime. The Lovato SG22PA300R diverts transient overvoltages safely to earth before they reach connected equipment, helping improve installation reliability and equipment availability.
Its replaceable protection cartridge, integrated thermal protection and remote signalling contact make it an excellent solution for industrial automation systems, commercial buildings, machine control panels and photovoltaic electrical installations.
