Mounting and panel integration
The 3RT2045-1CP04-3MA0: Mounts via screw or snap-on onto 35 mm DIN rail (DIN EN 60715). Dimensions: 70 mm wide, 140 mm high, 195 mm deep. The mounting position allows ±180° rotation on a vertical surface and ±22.5° forward/backward tilt. Minimum clearances: 10 mm upwards, 10 mm downwards, 10 mm at the side, 20 mm forwards.
Wiring and conductor ranges
Main contact terminals accept solid conductors 2.5–16 mm² or stranded 6–70 mm². The magnet coil uses screw-type terminals. Auxiliary switch terminals accept 2x (0.5–1.5 mm²) solid or stranded, or 2x (0.75–2.5 mm²).
Switching performance and thermal limits
