Siemens 3RT20181AK610UA0 Contactor S00

Product Description

The SIEMENS 3RT20181AK610UA0 is a Size S00 IEC motor contactor designed for switching and controlling three-phase motor loads in industrial and commercial electrical systems. This compact contactor fits into tight control panel enclosures while delivering reliable motor switching performance. The S00 frame size is among the smallest in the IEC contactor range, making it well suited for low-horsepower motor applications where panel space is at a premium. The unit weighs 0.514 pounds and measures 2.421 inches long by 1.969 inches wide by 3.051 inches tall, making it a space-efficient choice for dense control cabinet layouts. Licensed electricians and industrial controls technicians are the primary installers for this type of device.

This contactor is suited for use in residential, commercial, and light industrial motor control applications. Typical install scenarios include motor control centers, machine control panels, HVAC equipment control circuits, and conveyor or pump motor starters. The S00 frame size is commonly specified for smaller motor loads where a compact footprint is required. It is packaged individually, one unit per pack.

Key Features

• Size S00 IEC frame — compact footprint for dense panel layouts
• Overall dimensions of 2.421 inches x 1.969 inches x 3.051 inches allow installation in space-constrained enclosures
• Lightweight construction at 0.514 pounds reduces mounting stress on DIN rail or panel surface

Compatibility

Designed as an OEM-style IEC Size S00 contactor for use in motor control and switching applications where a compact three-phase contactor is specified.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. Disconnect and lock out all power sources to the control panel before removing or installing the contactor. Verify that coil voltage and contact ratings match the application requirements before energizing the circuit. Do not exceed the contactor's rated load when sizing for motor applications.
