Product Positioning

The 3RT2023-2AK60 is the AC coil version of the SIRIUS 3RT2 S0 frame contactor. The coil is rated for 110V/50Hz and 120V/60Hz dual-frequency operation, covering common control voltage specifications in Taiwan and some export machines. The operating voltage range is approximately 0.8~1.1 times the rated value at 50Hz and approximately 0.85~1.1 times at 60Hz. The main circuit maintains the standard S0 frame specifications, with an AC-3 rated current of 9A and a rated power of 4kW at 400V. The auxiliary contacts are one set of normally open and one set of normally closed. The terminals use spring-loaded connections, allowing for quick wiring without additional screws or tools, making it suitable for direct replacement of existing distribution panels with AC control power supplies.

Core Product Advantages and Features

110/120V AC dual-frequency coil

The coil is compatible with two mains frequency specifications: 50Hz/110V and 60Hz/120V. The operating voltage range is approximately 0.8~1.1 times and 0.85~1.1 times the rated value, respectively, providing flexibility to adapt to different production line power supplies.

Spring-loaded terminal blocks

Both the main circuit and the auxiliary circuit use spring-loaded terminals, eliminating the need for screwdrivers during wiring and speeding up panel assembly and subsequent maintenance.

1NO+1NC auxiliary contact

It is equipped with one set of normally open and one set of normally closed instantaneous auxiliary contacts to meet the needs of general interlocking circuits and operation status indication.

S0 frame, AC-3 9A/4kW

The AC-3 three-pole main contact has a rated current of 9A, a rated power of 4kW at 400V, complies with IEC/EN 60947-4-1, and has a mechanical life of 10 million cycles.
