Siemens SIRIUS 3RF2340-3AA06 is a 1-pole solid-state contactor (3RF2 family) rated for 40 A and 600 V, with a 24 V DC control coil. It provides a single normally open (1NO) contact and uses ring terminal lug connections for wiring. This device switches AC loads up to 600 V under a 24 V DC control signal, making it suitable for compact control tasks in automation where solid-state switching is advantageous. Typical applications include energizing motors, heaters, or other automated loads in control panels and automation circuits that require fast, reliable switching with a small footprint.
