Mounting and integration
The 3RT1017-1AM21-0UA0: Mounts via screw or snap-on onto 35 mm DIN rail per EN 50022. The S00 frame is compact at 45 mm wide, 57.5 mm tall, and 72 mm deep — fits tight panel layouts. Side-by-side mounting is allowed with 6 mm spacing to the side; front face is IP20, so it's safe for open-panel work. Operating temperature range is -25 to +60 °C, which covers most indoor industrial environments.
Coordination and protection
For Type 2 coordination (no damage to the contactor under short circuit), the required upstream fuse is gL/gG 20 A. For Type 1 coordination (contactor may be damaged but no fire risk), it's gL/gG 35 A. The degree of pollution is 3, meaning it's rated for conductive pollution environments typical of control panels.
