        More Information

        Overview Manuals Main Pole Path Coil Control Auxiliary Feedback Motor Starter Coordination

        Features:

        • Switches three AC phases through one mechanically linked contact system.
        • Uses a 220 V AC 50/60 Hz coil to operate the size S2 contactor mechanism.
        • Carries 50 A AC-3 at 400 V for a documented 22 kW motor duty.
        The coil circuit commands the armature while the three main poles carry the motor power.

        Utilization category and operating voltage determine the permitted current and motor rating.

        Overload and short-circuit devices coordinate with the contactor but provide protection outside the switching mechanism.

        The Siemens 3RT5036-1AN20 SIRIUS 3RT5 S2 3-Pole AC Power Contactor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
        Siemens 3RT5036-1AN20 SIRIUS 3RT5 S2 3-Pole AC Power Contactor Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

        Following three-phase power through the contactor

        • Line terminals: The three incoming phases connect to the upper main-circuit terminals.
        • Linked contacts: One armature closes all three normally open main poles together.
        • Load terminals: The outgoing phases continue from the matching lower terminals to the motor branch.
        • Open state: Removing coil voltage separates all three power paths at the same mechanism.

        Using the 220 V AC control circuit to operate the armature

        • Coil supply: The A1 and A2 circuit receives 220 V AC at 50 or 60 Hz.
        • Magnetic action: Coil current pulls the armature into the closed position.
        • Release: Loss of control power allows the mechanism to reopen the main contacts.
        • Supply match: The actual control voltage and frequency must agree with the coil marking.

        Adding control-state contacts without carrying motor current

        • Extension support: An auxiliary switch block can be attached to the contactor.
        • State indication: Auxiliary contacts can report whether the mechanism is operated.
        • Interlocking: A normally closed auxiliary path can block an opposing control circuit.
        • Separate rating: Auxiliary contacts follow control-circuit limits rather than the main AC-3 current.

        Combining switching with separate protection

        • Contactor duty: The 3RT5 device starts and stops the motor on command.
        • Overload relay: A coordinated relay monitors sustained motor overcurrent.
        • Short-circuit device: A fuse or breaker interrupts high fault current.
        • Selection basis: Motor power, operational category and protective-device coordination are checked together.
        Description
        Siemens 3RT5036-1AN20 is the SIRIUS 3RT5 size S2 power contactor for three-phase motor and general AC switching. Its 220 V AC coil moves three normally open main contacts together so the control circuit can energize or isolate the load path.

        When the coil of 3RT5036-1AN20 is energized at 50 or 60 Hz, the armature closes all three poles and establishes the phase paths from line to load. Removing the control voltage opens those poles together and interrupts the motor circuit.

        The AC-3 rating of 3RT5036-1AN20 links a 50 A operational current to a 22 kW motor at 400 V. AC-1 duties use different current limits because resistive switching places a different electrical demand on the contacts than motor starting and interruption.

        Screw terminals on 3RT5036-1AN20 separate the main power conductors from the coil and optional auxiliary circuits. Overload and short-circuit protection remain external coordinated devices, while the contactor supplies the commanded switching action.

        VIEW ALL FAQS
        Why does Siemens 3RT5036-1AN20 hum without closing firmly?
        Measure the control voltage and frequency at the coil of Siemens 3RT5036-1AN20 and check for mechanical obstruction.
        Can 3RT5036-1AN20 switch a 22 kW motor at any voltage?
        No. The 22 kW rating of 3RT5036-1AN20 is tied to the documented 400 V AC-3 duty.
        What protects a motor if Siemens 3RT5036-1AN20 is only a contactor?
        Use coordinated overload and short-circuit devices with Siemens 3RT5036-1AN20; the contactor itself performs commanded switching.
        How can Siemens 3RT5036-1AN20 provide starter feedback?
        Fit a suitable auxiliary switch block to Siemens 3RT5036-1AN20 and wire the required NO or NC control contact.
        What should be checked if one phase is missing through 3RT5036-1AN20?
        With power isolated, inspect the corresponding line terminal, main contact and load conductor of 3RT5036-1AN20.
        Which control supply belongs to Siemens 3RT5036-1AN20?
        Siemens 3RT5036-1AN20 uses a 220 V AC coil designed for 50/60 Hz operation.
