The Siemens 3RT2015-1JB42 is a SIRIUS 3RT2 series 3-pole power contactor designed for reliable switching of three-phase motors and industrial electrical loads. It features mirror contact elements, screw terminal connections, and a 24 V DC control coil, making it suitable for use in motor control centers (MCCs), automation systems, HVAC applications, machinery, and industrial power distribution systems.
This model belongs to the compact S00 frame size and is rated for AC-3 duty up to 7 A, with a motor capacity of approximately 3 kW at 400 V AC, depending on application conditions. It is commonly used in light-duty motor switching and control applications in industrial environments.
According to Siemens technical documentation, the 3RT2015-1JB42 includes a 3-pole switching system, 1 NC auxiliary contact, integrated diode for coil suppression, and screw terminal connection, ensuring stable operation and compatibility with PLC outputs.
The integrated mirror contact elements provide safe feedback of the main contact position, which is essential for PLC interlocking, safety circuits, and system monitoring. This helps improve operational safety and fault diagnostics in automated electrical installations.
