Product Positioning

The 3RT2026-1AL20 is a SIRIUS 3RT2 series S00 frame three-pole contactor, rated at 25A AC-3 with a load of 11kW at 400V. The control coil is rated at 230V AC, 50/60Hz dual frequency, one of the most common control voltage combinations in Taiwanese switchboards. It features 1 NO + 1 NC auxiliary contacts, and the main circuit, auxiliary circuit, and coil terminals are all screw-type, facilitating on-site installation and future maintenance by general electrical control personnel.

Core Product Advantages and Features

230V AC 50/60Hz Dual-Frequency Coil

It supports both 50Hz and 60Hz AC mains power, and can be used with 110/220V control circuits in general factories in Taiwan.

1NO+1NC Built-in Auxiliary Contacts

A single normally open and a single normally closed signal are sufficient to complete basic start/stop feedback and simple interlocking, without the need for additional auxiliary modules.

All-screw terminal design

The main circuit, auxiliary circuit, and coil terminals are all screw-type, and the wiring tools and procedures are consistent with the usual operations in Taiwan.

S00 standard framework, high spare parts interoperability

It shares the same shape and mounting holes as the 1NO+1NC series with the same frame, making inventory planning and quick replacement more convenient.

3RT2026-1AN20

The 220V AC dual-frequency coil is a common control voltage in Southeast Asia and some Taiwanese factories. It features 1NO+1NC auxiliary contacts with IP20 protection and 690V insulation. The information has been cross-confirmed from the specification sheets of multiple distributors.

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.

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.
