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.

Product Positioning

The 3RT2026-1AN24 belongs to the SIRIUS 3RT2 S00 frame, is an AC-3 rated 25A/11kW three-pole contactor, and features a 220V AC, 50/60Hz dual-frequency coil design. The biggest difference from the basic model is its auxiliary contact configuration: 2NO+2NC. This adds an extra set of normally open and normally closed contacts compared to the more common 1NO+1NC configuration. This makes it suitable for control panels requiring two independent feedback signals simultaneously, or for applications with complex interlocking circuits, such as when used with another contactor for interlocking, or when status feedback needs to be sent to multiple monitoring devices.

Core Product Advantages and Features

2NO+2NC Double Auxiliary Contacts

One contactor can provide two sets of normally open and two sets of normally closed signals simultaneously, which is suitable for interlocked circuits or applications that require separate feedback to different controllers.

220V AC 50/60Hz coil

With a dual-frequency design, it can directly use both 50Hz and 60Hz power supplies, providing greater flexibility for cross-regional equipment planning.

The S00 frame has the same outer shell as the standard model.

It shares the same mounting holes and dimensions as the 1NO+1NC models in the same series, so there is no need to redesign the panel when replacing or expanding the wiring.

25A/11kW load capacity

The AC-3 is rated at 11kW at 400V, which is sufficient to meet the direct start and stop requirements of a typical three-phase asynchronous motor.
