That AC-3e rating means it's specifically designed for starting and stopping squirrel-cage motors — the 'e' suffix indicates it meets the enhanced endurance classification for higher electrical life in motor duty. The 12 V DC coil suits control systems running on a low-voltage DC bus, common in modern PLC-driven panels where you want to keep AC out of the control cabinet. Auxiliary contacts come as 1 NO plus 1 NC, which is enough for basic feedback to a PLC input and a seal-in circuit without adding an aux block. Spring-loaded terminals (cage clamp style) mean no screw torque worries on the install — strip, push, done. That's a time-saver when you're swapping a contactor on a live line and every minute counts. The packaging dimensions (108.5 x 54.0 x 115.5 mm) give you the envelope for spacing in the cabinet. Coil draws from a 12 V DC supply; check your power budget against the inrush and hold-in currents from the datasheet.","metaTitle":"Siemens 3RT2026-2BA40 Power Contactor, 25 A AC-3e, 11 kW, 12","metaDescription":"Siemens 3RT2026-2BA40 power contactor, AC-3e rated 25 A / 11 kW at 400 V, 3-pole, 12 V DC coil, 1 NO + 1 NC aux, spring-loaded terminals, size S0.
