Product Positioning

The SIRIUS 3RT2025-1AC20 is an S0 frame three-pole contactor with an AC-3 rated current of 17A and an output of 7.5kW at 400V. It is the most common 24V AC coil specification in factory motor control circuits, and comes standard with 1NO+1NC auxiliary contacts and screw terminals, allowing direct compatibility with standard 24V AC control transformers. Kenxin Motors has stock available, providing genuine Siemens parts and fast delivery.

Core Product Advantages and Features
24V AC coil is a standard specification in the industry.
The coil is rated at 24V/50-60Hz, which is the most common control voltage in Taiwanese factory switchboards, and replacement and spare parts are relatively easy.
1NO+1NC auxiliary contact standard configuration
It provides operational status feedback and interlock protection to meet the monitoring needs of general motor starting circuits.
S0 frame 17A/7.5kW main circuit
The AC-3 is rated at 17A and 7.5kW (400V), while the AC-1 is rated up to 40A. Both are suitable for continuous loads such as conveyor belts and pumps.
Screw terminals, IP20 protection
Both main and auxiliary circuits use screw terminals, the front panel has IP20 protection, and the mechanical life is 10 million cycles, making it suitable for long-term operation.
