Rated at 51.3 A, it provides UL489-compliant, trip-free protection that responds to overloads with a hydraulic delay, helping minimize nuisance trips from temperature variations and inrush currents in 50\/60 Hz networks. This panel-mount device typically uses screw termination and is intended for use in distribution panels, HVAC\/R equipment, lighting-control panels, and general EDP applications where reliable overcurrent interruption is essential. The 209-series family is known for rugged performance, able to withstand high pulses and shocks (up to 100 g repeatedly) and to resist moisture-related degradation with protective finishes, making the M-209 suitable for demanding environments. With its hydraulic-magnetic mechanism, the breaker provides stable trip characteristics over varying temperatures and supply conditions, ensuring circuit protection even in installations subject to vibration and harsh conditions. As a UL489-listed, multi-pole protection solution, the M-209 complements other Airpax 209-series devices in creating compact, modular protection schemes for modern electrical panels and control systems.\u003c\/p\u003e\u003c\/div\u003e","brand":"AIRPAX","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657155477806,"sku":null,"price":152.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_06636f48-8bc2-4175-ba1c-bf18223bbbc6.jpg?v=1769466479","url":"https:\/\/plgautomation.com\/products\/airpax-m-209-circuit-breaker","provider":"PLG Automation ","version":"1.0","type":"link"}
