Product Positioning

The 3RT2025-1AR60 is a model in the SIRIUS 3RT2 series S00 frame contactor series. Its control coil directly adopts the 400V AC (50Hz) / 440V AC (60Hz) "line voltage" specification, meaning it can be directly driven from a three-phase mains power supply without the need for a separate 24V or 230V control transformer. This is a common simplification solution for machine designs with limited panel space or those aiming to simplify the BOM and wiring hierarchy. The main circuit maintains the 3RT2025 family's AC-3 17A / 7.5kW (400V) capability, reaching 11kW at 690V. The auxiliary contacts 1NO+1NC can carry 10A at 230V and 3A at 400V under AC-15 conditions. The terminals are screw-type, with dimensions of 85×45×97mm and a weight of approximately 0.420kg. The closing delay is approximately 8-40ms. It has certifications from multiple classification societies, including UL, CSA, CCC, KC, EAC, ABS, BV, DNV, LR, RINA, and RMRS. It is also suitable for applications with high certification requirements, such as marine and industrial electrical control panels.

Core Product Advantages and Features
Line voltage coil without control transformer
The coil is directly driven by a 400V/440V mains power supply, eliminating the need for an additional control transformer and related wiring, thus simplifying the internal components and reducing costs.
Broad classification society certification
In addition to general industrial certifications, it has obtained confirmations from classification societies such as ABS, BV, DNV, LR, RINA, and RMRS, making it suitable for marine electrical control panels.
quick action reaction
The closing delay is approximately 8–40 ms, and the action response speed meets the timing requirements of general motor start-stop control.
Standard screw terminals
Both the main circuit and the auxiliary circuit use screw-type terminals for easy wiring and periodic inspection.
