Product Positioning

The 3RT2027-1AC20 is the most commonly selected standard model in the Siemens SIRIUS 3RT2 series S0 housing. Its AC-3 main circuit is rated at 32A, 15kW at 400V, and includes 1NO+1NC auxiliary contacts for status feedback and interlocking. The 24V AC 50/60Hz coil is compatible with most Taiwanese factory control circuit voltages. Kensun Motors has stock available with an authorized Siemens warranty, suitable for general industrial control applications such as motor starting/stopping, pumps, and fans.

Core Product Advantages and Features
Industry mainstream standard model
The 24V AC/1NO+1NC combination is the most common selection, with high compatibility in terms of parts and replacements, and convenient maintenance and replacement.
S0 casing with exquisite design
With a compact size of 85×45×97mm and DIN rail mounting, it is suitable for control panel configurations with limited space.
Multiple usage level markings
The rated currents of AC-1, AC-3, and AC-4 are also indicated to facilitate selection based on the actual load type (resistive/motor/frequent start-stop).
Stable and durable performance
The mechanical life is approximately 10 million cycles, and the AC-4 electrical life is approximately 200,000 cycles, ensuring stable long-term operation.
