Mounting and integration
The 3RT1016-2AV02: Mounts via screw or snap-on onto 35 mm DIN rail per EN 50022. The 45 mm width and 60 mm height fit a standard 6-module enclosure slot; 73 mm depth leaves clearance for front-panel wiring ducts. Side-by-side mounting is permitted without derating, so you can gang multiple contactors on a single rail for multi-motor groups. IP20 on the front and at the terminals means it's protected against finger contact but requires enclosure in a panel rated for the environment.
Coordination and protection
For Type 2 coordination (no damage after a short circuit), use a gL/gG fuse rated 20 A. For Type 1 coordination (allowable damage but safe interruption), the fuse can go up to 35 A. The degree of pollution 3 rating means the contactor is suitable for industrial environments with conductive dust or moisture — common in machine-tool and conveyor applications.
