Siemens AG 3RT1015-1BB41 3-Pole Power Contactor

Siemens 3RT1015-1BB41 is a SIRIUS 3-pole power contactor designed to switch AC-3 loads in three-phase circuits. This 3RT series device uses a 24 V DC coil and comes in the S00 frame size with screw terminals, enabling compact panel mounting. It provides three main normally open contacts for reliable motor control, making it suitable for starting and stopping three-phase motors and other inductive loads. Rated for AC-3 operation at up to 7 A and up to 3 kW at 400 V, the contactor is engineered for space-efficient control solutions in automation panels. The unit is non-reversing, a common characteristic for standard motor-controlling contactors in the SIRIUS lineup, and aligns with Siemens' broader SIRIUS 3RT1x family; the recommended successor for this model is 3RT2015-1BB41. Applications include three-phase motor control and other inductive loads in industrial panels, where a compact, 24 VDC-coiled contactor is required. The 3RT1015-1BB41's screw-terminal wiring and robust construction support reliable operation in industrial environments, with the 3-pole, 3NO configuration providing straightforward switching of three-phase loads in many control schemes.
