Product Positioning

The 3RT2027-1AN24 is a Siemens SIRIUS 3RT20 series S0-size three-pole power contactor. Its control coil is powered by 220V AC, with a rated operating current (AC-3) of 32A, and can handle 400V switchable 15kW motor loads. Unlike the standard 1AN20, this model has two sets of normally open and two sets of normally closed auxiliary contacts built into the main body, providing multiple signals simultaneously for start feedback, fault monitoring, or interlocking, reducing the wiring time required for additional auxiliary contact blocks. Both main and auxiliary circuits use screw terminals, and the operating temperature range is -25°C to +60°C, making it suitable for motor control circuits requiring multiple auxiliary signal points and driven by 220V AC.

Core Product Advantages and Features

220V AC coil

This switchboard is compatible with common 220V single-phase control voltage and is suitable for switchboards used in voltage systems in the Asia-Pacific region.

2NO+2NC auxiliary contacts

It provides two normally open and two normally closed signal points at a time, which can simultaneously meet the needs of feedback, monitoring and interlocking.

32A/15kW main circuit capacity

AC-3 rated operating current 32A, can carry a 15kW motor load at 400V, S0 body dimensions.

Screw terminals / Wide temperature range

Both main and auxiliary circuits use screw terminals, and the operating temperature ranges from -25°C to +60°C, making them suitable for general industrial environments.
