Siemens Industry 3RT2015-2BB44-3MA0 Contactor

Siemens Industry 3RT2015-2BB44-3MA0 is a compact 3-pole power contactor from the 3RT2 family (size S00) with a 24 V DC coil, designed for AC-3e/AC-3 duty. It switches up to 7 A and drives motors up to 3 kW at 400 V, making it suitable for starting and stopping small to mid-size three-phase motors in automation panels. The device integrates two normally open and two normally closed auxiliary contacts, enabling interlocking, status feedback, or PLC signaling alongside the main contacts, and it features spring-loaded terminals for secure, vibration-resistant connections with a captive auxiliary switch built into the assembly. This combination provides straightforward motor control in compact installations, ideal for conveyors, fans, pumps, and small machine tools where a compact motor starter with integrated signaling options is required.
