Physical footprint: 90 mm wide x 58 mm high x 57 mm deep. That's about 3.5 x 2.3 x 2.2 inches. Compact enough to fit a tight cabinet, and the IP20 terminals keep live parts behind the finger-safe bezel. Mounts via the integral DIN-rail clip or screw-fixing, whichever your panel layout demands. The factory busbar means no extra interlock wiring — just run motor leads and coil control. Keep it dry: the TC protective treatment handles damp heat, but don't flood it.
