It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, with a ±180° rotation possible on vertical surfaces and ±22.5° tilt forward/backward. The coil is rated for 175... 280 V AC, and the coil terminals are spring-type for tool-less wiring.
The 3RT2035-3SP30 is listed at the current production stage, meaning it remains in active manufacture with no announced discontinuation.
Key Ratings and Their Meaning
The contactor carries an MTBF of 52 a, which translates to a mean time between failures of 52 years under typical industrial operating conditions — a strong reliability indicator for continuous-duty applications. The coil inrush current peaks at 43 A, so the control transformer and wiring must be sized to handle this momentary surge.
Physical footprint: 114 mm height, 55 mm width, 130 mm depth. These clearances must be maintained for heat dissipation and arc-fault containment. The spring-type coil terminals accept 2x (0.5... 2.5 mm²) solid or stranded conductors.
