Siemens 3RT1015-2HB41 Power Contactor

Siemens 3RT1015-2HB41 is a compact, three‑pole power contactor designed for AC‑3 duty, ideal for reliably switching three‑phase motors up to about 3 kW at 400 V with a 24 V DC coil. The main circuit provides three normally open (3 NO) contacts in a Size S00 frame, with spring‑type terminals for secure wiring. In addition to the AC‑3 rating of 7 A at 400 V (motor load), it also lists an AC‑1 rating up to 18 A, offering flexibility for lighter loads or control circuits. The coil is 24 V DC, and the device is built to operate across a wide ambient range from -25 to +60 C, with IP20 protection on the front and a mechanical life in the tens of millions of cycles (roughly 30,000,000). This Siemens contactor is suited for motor control in automation applications such as conveyors, pumps, fans, and other three‑phase loads where a compact, reliable control switch is required in control cabinets or integrated PLC outputs. Availability in the HB variant indicates a 24 V DC coil with integrated or compatible termination options for easy mounting in standard control panels. For reference, this model sits within the Siemens 3RT family and has seen successor models like 3RT2015‑2HB41 introduced in later product lines. Overall, 3RT1015‑2HB41 combines a 3‑pole, 3‑NO main contact configuration with a 24 V DC coil in a small S00 package, delivering clear motor‑switching capability with durable mechanical life and straightforward wiring.
