Product Positioning

The 3RT2026-1AN20 is a SIRIUS 3RT2 series S00 frame contactor, a three-pole, AC-3 rated 25A/400V 11kW contactor. The control coil is 220V AC, 50/60Hz dual-frequency, suitable for production lines with different mains frequencies. It features 1 NO + 1 NC auxiliary contacts, and both main and auxiliary circuits use screw terminals. It has an insulation voltage of 690V, a rated impulse withstand voltage of 6kV, an IP20 protection rating, and a mechanical life of 10 million cycles. This data is available in RS Components, Mouser, and distributor specification sheets, with consistent and mutually corroborating values.

Core Product Advantages and Features

220V AC 50/60Hz universal coil

The same contactor can be used in 50Hz or 60Hz power supply environments, reducing the hassle of having multiple part numbers due to different power specifications in different regions.

1NO+1NC standard auxiliary contact

One normally open and one normally closed signal can be obtained without purchasing an auxiliary contact socket, which can meet most start/stop feedback and interlocking needs.

690V insulation/6kV impulse withstand

Both the main and auxiliary circuits have passed high-level insulation tests, making them suitable for use in distribution boxes in factory environments with large voltage fluctuations.

IP20 protection and multiple international certifications

It has basic IP20 protection and has obtained safety certifications from multiple countries such as UL, CSA, CCC, and KC, making it easy to adopt equipment shipped across regions.

3RT2026-1AN24

The 220V AC 50/60Hz coil, equipped with 2NO+2NC auxiliary contacts, offers twice the number of signal points compared to the standard 1NO+1NC, making it suitable for control panel designs requiring star-delta switching, multi-segment interlocking, or simultaneous feedback of two independent signals.

3RT2026-1AL20

The 230V AC dual-frequency coil is one of the most commonly used voltages in Taiwanese control panels. The 1NO+1NC auxiliary contacts and screw terminal design make field wiring and maintenance more intuitive and convenient.

3RT2026-1AK60

The same coil can operate at 110V at 50Hz and 120V at 60Hz, making it suitable for equipment destined for the US/North America or dual-power supply lines. It also has additional marine classification certifications from ABS, BV, and DNV.
