Seanro 2P AC Surge Protector Device (SPD)
The Seanro 2-pole AC surge protector is a protective device used in electrical distribution boards to safeguard equipment against voltage surges caused by lightning, power switching, or grid disturbances. The “2P” design protects both live and neutral lines in a single-phase AC system (typically 220–240 V). It works by diverting excess voltage safely to earth, preventing damage to appliances, inverters, and other sensitive equipment. It is DIN-rail mounted and commonly used in homes, offices, and solar installations.
