Product description

The Siemens 3RA6120-2BB33 is a SIRIUS Compact Direct On-Line (DOL) load feeder starter designed for low to medium-current motor control. It operates at 690V with a 24V AC/DC coil and a 50-60 Hz frequency. This starter is rated for currents from 0.32 to 1.25 amps and offers IP20 protection. The main circuit connection utilizes plug-in terminals (without terminals), while the auxiliary circuit employs spring-type terminals.

This configuration is suitable for applications where quick main circuit disconnection is desired, along with vibration-resistant and easy-to-wire auxiliary connections. It's valuable for small motor applications in automation, control panels, and general industrial equipment where compact size and ease of maintenance are key.
