The Siemens SIRIUS 3RT2037-1AL20-1AA0 is a Size S2 power contactor rated for switching motor loads up to 65 A at 480 V in AC-3 duty — that's the current it can make and break under full motor starting conditions, not just resistive heating.
The headline number is 65 A at 480 V in AC-3 — that's the motor-switching rating, not the resistive (AC-1) number. If your motor nameplate draws 60 A full-load, this contactor has headroom. The coil is rated for 230 V at 50 Hz, so it's a standard European control voltage; verify your transformer taps if you're running 60 Hz at a different voltage. The auxiliary switch is already integrated — no separate add-on module needed for basic status feedback.
The mounting position is standing on a horizontal surface. Clearances: 10 mm upward and forward, 10 mm downward, 6 mm at the sides. That's tight — you can pack these next to each other on the rail without worrying about arc flash between phases if you stay within those gaps. The S2 frame size is a common footprint; if you're replacing a different brand's 65 A contactor, check the rail depth and side clearance before committing the BOM.
