Siemens SIRIUS 3RT19364BA31 connettore parallelo per contattori S2/S3, 3 poli, senza morsetti

When a single contactor cannot handle the required current, this parallel connector links multiple SIRIUS contactors to share the load. It provides a direct connection between the main current paths of 3-pole contactors in frame sizes S2 and S3, without terminal clamps.

Who is it for

Electrical installers and panel builders who need to increase current capacity by paralleling Siemens SIRIUS 3RT1 contactors. It suits applications up to 690 V AC (1000 V AC) with pollution degree 3.

Main features

• Parallel connection of main current paths
• For 3-pole contactors, frame sizes S2 and S3
• Without terminal clamps
• Rated insulation voltage 690 V AC
• Rated impulse withstand voltage 6 kV
• Operating temperature -25 to +60 °C

Tips

Verify that the contactor terminals are clean and free of oxidation before mounting the connector. Torque settings must follow the contactor manufacturer's instructions to ensure a reliable low-resistance connection.
