Product Positioning

The 3RT2025-2AL20 is also a SIRIUS 3RT2 series S00 frame contactor. Its control coil specifications are marked as 230V AC, supporting dual-frequency operation at 50Hz and 60Hz. Measuring starting power is approximately 68VA, and holding power is approximately 7.9VA. For equipment manufacturers exporting to regions with different power frequencies, the same part number can be used to cater to both 50Hz and 60Hz markets, simplifying part preparation and inventory management. The main circuit maintains the family standard capability of AC-3 17A/7.5kW (400V). The auxiliary contacts are 1NO+1NC, capable of carrying 10A at 230V and 3A at 400V under AC-15 conditions, sufficient to drive solenoid valves or indicating elements in general control circuits. Both the main and auxiliary circuit terminals use a spring-loaded design. With dimensions of 102×45×97mm and a weight of approximately 0.448kg, it is a relatively lightweight model among spring-loaded terminal block models in the same series, suitable for control box configurations with high installation density.

Core Product Advantages and Features
50/60Hz dual-frequency coil compatibility
The same part number can be used in both 50Hz and 60Hz power supply environments, making material preparation simpler for export-oriented equipment or factories located in different regions.
Low power retention design
The measured holding power is approximately 7.9VA, and the coil temperature rise and power consumption are both low under prolonged power-on.
Spring-type terminals are fully adopted
Both the main circuit and the auxiliary circuit use spring-loaded wiring, eliminating the need for screws during installation and replacement.
Lightweight body
Weighing only about 0.448kg, its 102×45×97mm dimensions facilitate high-density side-by-side installation within a control box.
