Product Positioning

The 3RT2026-1AK60 belongs to the SIRIUS 3RT2 series S00 frame contactor. The AC-3 version is rated at 25A and 11kW at 400V, while the AC-1 version can reach 40A. The control coil is designed to be rated at 110V at 50Hz and 120V at 60Hz, a common dual-voltage coil design in North American power specifications, with 1 NO + 1 NC auxiliary contacts. In addition to general UL, CSA, CCC, KC, and EAC certifications, this model has also obtained certifications from multiple classification societies such as ABS, BV, DNV, LR, RINA, and RMRS, making it suitable for use in marine or maritime switchboards.

Core Product Advantages and Features

50Hz/110V, 60Hz/120V dual voltage coil

The same coil automatically corresponds to the 110V or 120V rated value according to the power supply frequency, which is suitable for production lines for US and North American specifications or dual power supply environments.

Certified by multiple classification societies

In addition to general industrial safety regulations, it has also passed ABS, BV, DNV, LR, RINA, and RMRS marine classification certifications, and can be used in marine and maritime power distribution systems.

AC-1 rated at 40A

Except for AC-3 motor start-stop, the rated current can reach 40A under AC-1 resistive load category, which has a high degree of application flexibility.

690V insulation, 6kV impulse withstand

The main and auxiliary circuits have an insulation voltage of 690V, a rated impulse withstand voltage of 6kV, a mechanical life of 10 million cycles, and high stability during long-term use.

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.

3RT2026-1AH20

A 48V AC coil is a relatively low control voltage level, suitable for applications with strict requirements on the risk of coil inductance, or for situations where existing control circuits already use a 48V configuration.

3RT2026-1AG24

The 110V AC 50/60Hz coil, equipped with 2NO+2NC auxiliary contacts, provides twice the number of signal points compared to the standard model, making it suitable for distribution panels that require simultaneous feedback of multiple statuses or interlocking control.
