Siemens SIRIUS 3RT2 3-Pole Power Contactor, 7 A, 24 V DC Coil, 1NO+1NC, Screw Terminals, S00 3RT20151BB411AA0

The 3RT2015-1BB41-1AA0 from the SIRIUS 3RT2 series is a compact 3-pole power contactor in size S00, engineered for reliable switching of motors up to 3 kW at 400 V AC-3. Its 24 V DC coil and integrated 1 NO + 1 NC auxiliary contacts make it a practical choice for control circuits requiring feedback without additional hardware.

Highlights

• Rated operational current: 7 A (AC-3, 400 V) and 18 A (AC-1, 400 V)
• Control supply voltage: 24 V DC
• Integrated auxiliary contacts: 1 NO + 1 NC
• Screw terminals for main and control circuit
• Mounting on DIN rail or by screw

In daily use

This contactor suits motor starting and resistive load switching in industrial control panels. The screw terminals provide secure connections, and the S00 footprint saves space on the DIN rail. With a mechanical endurance of 30 million cycles and electrical endurance of 10 million cycles (AC-3), it is built for long service in repetitive operations.
