3-hole control box with green indicator light 230V, flush red button (1NC), flush green button (1NO), 1 metric M20 cable gland ST22K3\06-1

Control box for professional machine control

The ST22K3\06‑1 control box is a complete solution for controlling and signaling the operating status of electrical devices in industrial environments. Equipped with three control elements - a red emergency button (1NC), a green emergency button (1NO), and an LED signal lamp with a voltage of 230V - it ensures full control over production processes.

Construction and housing materials

The control box housing is made of high-quality plastic, which guarantees additional electrical insulation (class II protection) and durability during use. The grey color of the cover fits perfectly into the aesthetics of modern industrial installations.

The IP65 protection rating ensures full resistance to dust and low-pressure water jets, enabling installation in difficult environmental conditions - from production halls to construction sites. The design includes one M20 metric cable gland, which allows for the safe entry of installation wires.

Electrical parameters and compatibility

The box supports a wide range of operating voltages: for alternating current 230‑500V (50Hz) and for direct current 24‑220V. The contact elements ensure current transmission of up to 2.5A, making the box suitable for most control applications.

The contact configuration includes one normally open (NO) contact and one normally closed (NC) contact, allowing for the implementation of various logic functions in automation systems. Mounting on a TH35 rail facilitates installation in switchboards and control cabinets.

Application and functionality

The control box finds wide application in:

• Electric drive control - switching motors and other energy consumers on/off
• Operating status signaling - the LED lamp informs about system activity or readiness for operation
• Safety systems - the red button can function as an emergency STOP
• Industrial automation - integration with PLC systems and controllers

The ST22 series allows for easy composition of individual configurations by selecting various button actuators and lamp bodies powered by 24V or 220V voltage.
