Siemens 3TB3922-0XF0 Contactor, 110V AC, 2.2kW, Size 0, Screw Terminal Original Brand New

Overview

The Siemens 3TB3922-0XF0 is a highly reliable AC contactor designed for switching resistive and inductive loads. It’s built for use in control circuits, motor control applications, and automation systems. This size 0 contactor operates on a 110 V AC coil and is rated for a power output of up to 2.2 kW at 400 V AC. It includes one normally open (1 NO) and one normally closed (1 NC) auxiliary contact, providing flexibility for signaling and interlocking. The screw terminals ensure a secure and straightforward electrical connection.

Benefit

• Reliable Performance: Engineered by Siemens, a global leader in industrial automation, this contactor offers long-term reliability and durability.
• Space-Saving Design: The compact size 0 footprint allows for efficient use of panel space in control cabinets.
• Easy Installation: The screw connection terminals simplify wiring and installation, reducing setup time.
• Versatile: Suitable for a wide range of applications, including motor control, lighting, and heating systems.

Function

This contactor serves as an electrically operated switch. When the coil is energized with 110 V AC, the main contacts close, allowing power to flow to the connected load. The auxiliary contacts (1 NO + 1 NC) change state simultaneously, which can be used to provide feedback to a programmable logic controller (PLC) or to control other components in the system. The device is rated for a 2.2 kW load at 400 V AC3, which is a common industrial standard for switching motors.
