Product details

Switching capacity by duty class

The 3RT2036-1AN20: For resistive loads (AC-1) the maximum switching frequency is 1,000 operations per hour; for AC-3 motor starting it is 800 per hour; for AC-4 plugging/reversing it drops to 250 per hour — the duty class sets the thermal cycle limit, not the contactor's mechanical capability. Auxiliary switch is included on the contactor, which simplifies wiring for interlocking or status feedback without adding a separate block.

As a SIRIUS series power contactor, it is the standard motor-switching component in Siemens control panels and is widely cross-referenced in third-party panel designs.

Frequently asked questions

What is the 3RT2036-1AN20 rated current at 480 V?

The rated operational current is 52 A at 480 V in AC-3 duty, which is the motor-switching rating that determines the maximum three-phase induction motor current this contactor can handle.
