SIRIUS 3RV2342-4FC10 — Circuit Breaker for Starter Combinations
Physical envelope: 70 mm wide, 165 mm tall, 176 mm deep. That depth is the dimension from the DIN rail mounting surface to the furthest projection — important when you're laying out the gland plate or door clearance. That zero forward clearance means you can mount it flush against a panel backplate without worrying about arc flash venting.
Main circuit terminals are screw-type, accepting solid or stranded copper: 2x (2.5 to 16 mm²) per clamp, or a single conductor up to 70 mm². That's enough for a 40 A motor circuit at 480 V or 600 V without needing a reducer or pigtail.
