The 40DP32AG is an open-type non-reversing NEMA Size 1 heavy-duty magnetic contactor from Siemens' Class 40 series, engineered for reliable across-the-line switching and control of high-inductance electric motors and industrial power loads. Designed for 3-pole configurations operating at 600 and rated for a continuous full-load current of 27, this industrial contactor delivers dependable power switching for commercial HVAC equipment, pumping systems, and industrial automation control panels. Electrically, the 40DP32AG features heavy-duty silver-alloy contacts and an industrial-grade operating coil engineered for quick contact opening and low-bounce closure. Its heavy-duty arc chutes efficiently dissipate energy during inductive load breaks, protecting power contacts from pitting and ensuring reliable operation during heavy motor inrush and frequent cycling conditions. Mechanically, the 40DP32AG is built on an open-style steel frame designed for direct backpanel mounting inside custom industrial control enclosures and switchgear panels. Featuring accessible screw-clamp terminal blocks for straight-through power wiring, its compact profile maximizes panel space while offering clean access for adding auxiliary contact blocks and interlock accessories.
