SIEMENS 3RT10546AF36 Contactor Overview
The SIEMENS 3RT10546AF36 is a three-pole IEC magnetic contactor from the SIRIUS 3RT10 series rated for 115 A inductive and 160 A resistive loads. It operates on a 110-127V AC/DC coil and provides four auxiliary contacts in a 2NO/2NC configuration for control circuits. The unit uses screw terminals and surface mounting in an open-frame design without a NEMA enclosure.
Installation Requirements Check
Verify that the control circuit supplies 110-127V AC/DC to match the coil rating before wiring. Confirm the main circuit current does not exceed 115 A inductive or 160 A resistive for the three power poles. Ensure the panel layout accommodates the 6.77 in overall height and 0.47 in overall width for surface mounting with screw terminal connections.
Thermal and Power Characteristics
The contactor draws minimal coil power within the 110-127V AC/DC range during normal operation. An open-frame design without an enclosure allows unrestricted airflow around the frame size S6 body for heat dissipation. Mechanical switching noise is limited to the contactor actuation itself with no integrated fan or active cooling components.

Questions about this item
Does the contactor arrive with any auxiliary contacts or wiring accessories, or must they be purchased separately?
The unit includes four built-in auxiliary contacts — two normally open and two normally closed — and uses screw terminals for power and control wiring; no extra contact blocks or terminal kits are required for basic installation.
Which coil voltage and frame size match a 115 A inductive load in a 110 V control circuit?
The 110-127 V AC/DC coil and S6 frame are rated for 115 A inductive and 160 A resistive full-load current, making this version the correct choice for that load and control voltage.
How does the 115 A inductive rating translate when the contactor is mounted in a closed cabinet?
The 115 A inductive and 160 A resistive ratings are the nameplate values; actual continuous current in an enclosed cabinet depends on ventilation, conductor size and ambient temperature, so the installer must apply the appropriate derating factors for the specific enclosure.
