Siemens 3RT2027-1AN20 220V AC Power Contactor

Product Positioning

The 3RT2027-1AN20 is a Siemens SIRIUS 3RT20 series S0-size three-pole power contactor. Its control coil is powered by 220V AC and supports both 50Hz and 60Hz power frequencies. The rated operating current (AC-3) is 32A, suitable for 400V switching loads up to 15kW. The main body has one set of normally open and one set of normally closed auxiliary contacts, allowing direct wiring feedback of the main contact's operating state. Both main and auxiliary circuits use screw terminals. The front and terminal protection ratings are IP20, with a rated insulation voltage of 690V and the ability to withstand 6kV surges. It has a mechanical life of 10 million operations and is one of the most common standard main contactors in 220V AC control systems.

Core Product Advantages and Features

220V/50~60Hz Dual-frequency coil

It supports both 50Hz and 60Hz power supplies, making it suitable for export-oriented machines or applications where dual-frequency power supplies are used.

32A/15kW main circuit capacity
