Siemens 3TB4010-0XB0 Contactor, 24V AC, 9A, 4kW, 1NO Aux Contact Original Brand New

Overview

The Siemens 3TB4010-0XB0 contactor is a reliable and robust industrial switching device designed for controlling electric motors and other resistive loads. It operates on a 24V AC coil voltage and is suitable for use in circuits with a frequency of 50 Hz. With a rated current of 9A at 400V (AC-3), this size 0 contactor is ideal for applications requiring up to 4 kW of power. It comes equipped with a single normally open (1NO) auxiliary contact for additional control and signaling functions. The screw connection terminals ensure a secure and straightforward wiring process.

Function

The Siemens 3TB4010-0XB0 functions as an electrically operated switch. When the 24V AC coil is energized, it generates a magnetic field that closes the main contacts, allowing electrical current to flow to the connected load (e.g., a motor). Simultaneously, the 1NO auxiliary contact also closes, which can be used to provide feedback to a Programmable Logic Controller (PLC) or to activate an indicator light. When the coil is de-energized, the contacts open, interrupting the power supply to the load.
