It operates from AC power across 100–240 V and uses a two-position On\/Off signal to drive the damper to fully open or closed, while providing two SPDT auxiliary switches for end-of-travel or status signaling. The unit is built with a NEMA 4 enclosure, enabling outdoor and harsh-environment installations, and is part of Belimo’s EFB120-S N4 family designed for outdoor-protected, spring-return applications. This actuator combines rugged protection with straightforward control, making it a solid choice for dampers where immediate power loss should drive the damper to a safe, predefined position. \u003c\/p\u003e\u003c\/div\u003e","brand":"Belimo","offers":[{"title":"New","offer_id":51676863824174,"sku":null,"price":130.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_80044dea-1de7-44ee-9948-a9a8ba3eee6c.jpg?v=1769554486","url":"https:\/\/plgautomation.com\/products\/belimo-efb120-s-n4-damper-actuator-spring-return","provider":"PLG Automation ","version":"1.0","type":"link"}
