The LX9FL917 is a specific replacement coil for TeSys F contactors, rated for 48 V AC (40-400 Hz) and 48 V DC control circuits. It's a low-consumption design without a built-in suppressor module, meaning you'll need to add external suppression if the application demands it. Mechanical durability is rated at 5 million cycles. Coil inrush resistance is 2.81 Ω at 20 °C, holding resistance 20.8 Ω. Inrush power draw is 830 VA, holding power 47 VA. Heat dissipation runs 22.8 to 27.8 W once the contactor is sealed in.
The coil is rated for 48 V AC (40-400 Hz) and 48 V DC. Operating voltage tolerance is 0.85 to 1.1 Uc at 55 °C; dropout occurs between 0.25 and 0.5 Uc. The 60 ms opening time matters for safety circuits where fast dropout is required. The 50 ms closing time is standard for this contactor class. If your application needs faster break, this coil won't deliver it. That's typical for indoor panel environments but not suited for direct outdoor exposure or unheated enclosures in freezing climates.
