The FAAC 2357 Surge Protector for low voltage circuits is a compact, screw-terminal surge protection device that safeguards up to four circuits, including power, LED, data, and audible lines, across 5?V, 12?V, or 24?V systems. Engineered with self-restoring functionality, it automatically returns to service following typical transient events, ensuring continuous protection with minimal maintenance. The unit offers line-to-ground surge protection and connects easily using #22–#16?AWG screw terminals. Its condensed design allows it to fit into most low-voltage control enclosures or access panels with ease.
