Siemens Industrial Controls 3RT2036-1AC20 Contactor
The Siemens 3RT2036-1AC20 is a heavy-duty SIRIUS power contactor engineered for high-demand industrial and HVACR motor switching. Rated for 50A (AC-3) and up to 22 kW at 400V, this 3-pole contactor utilizes a 24VAC 50/60Hz coil to ensure stable actuation in low-voltage control circuits. Built on the Size S2 frame, it features screw terminals for secure conductor termination and DIN rail mounting capability for rapid integration into standard control panels. As a 3-phase standard device, it comes equipped with 1NO + 1NC auxiliary contacts, allowing for immediate feedback loops or interlocking without additional modules. This unit is the direct 3RT1036-1AC20 replacement, providing superior arc suppression and a mechanical service life of up to 10 million switching cycles. Its IP20 finger-safe design and climate-independent construction make it a reliable choice for NEMA size 2 motor starters and large-scale commercial HVAC contactor applications.
Key Benefits:
- High Amperage Capacity: Rated for 50A inductive loads and up to 70A (AC-1) resistive loads, suitable for large compressors and industrial motors.
- SIRIUS Innovation: Seamless compatibility with SIRIUS modular system accessories, including thermal overload relays and surge suppressors.
- Integrated Auxiliaries: Features factory-installed 1 normally open (NO) and 1 normally closed (NC) contacts for streamlined control wiring.
- Universal Mounting: Supports 35mm DIN rail or screw-on mounting with a flexible +/-180 degree vertical rotation tolerance.
- Robust Coil Design: The 24V AC coil operates reliably across both 50Hz and 60Hz frequencies, minimizing chatter and coil burnout.
Common Questions:
What is the difference between 3RT2036-1AC20 and the older 3RT1036 series?
The 3RT2036-1AC20 is the modernized successor in the SIRIUS line. While it is electronically and dimensionally compatible as a Siemens S2 contactor replacement, it offers improved efficiency and integration with the latest 3RV2 motor-protective circuit breakers.
Can I add more auxiliary contacts to this S2 frame?
Yes, while this unit includes 1NO/1NC base contacts, it can be expanded with front-mounted or side-mounted auxiliary switch blocks to accommodate complex logic requirements in industrial motor control.
Is this contactor suitable for 460V 3-phase motors?
This 3-phase magnetic contactor is rated for up to 40 HP at 460V, making it ideal for standard industrial motor voltages when controlled by a 24V transformer.
