Siemens 3TB4222-0XP1 Contactor 240V, 16A, 7.5kW with 1 NO + 1 NC Auxiliary Contact Original Brand New

Overview

The Siemens 3TB4222-0XP1 is a high-performance AC contactor designed for industrial control applications. This model is engineered to reliably switch electrical loads in a variety of systems, particularly for controlling motors. It operates at a frequency of 60 Hz and is suitable for a coil voltage of 240 V AC. With a rated operational current of 16 A at 400 V AC3, it can handle loads up to 7.5 kW. The contactor features an integrated auxiliary contact block with 1 normally open (NO) and 1 normally closed (NC) contact, providing additional flexibility for control and signaling circuits. Its robust size 1 frame and screw connection terminals ensure a secure and durable installation.

Key Features & Benefit

• Integrated Auxiliary Contacts: The built-in 1 NO + 1 NC contacts simplify wiring and reduce the need for external components, saving space and cost.
• Easy Installation: Features screw connection terminals for straightforward and secure wiring.
• Compact Design: The size 1 frame allows for installation in tight spaces within control panels.
• Optimal for US & North American Grids: The 60 Hz frequency rating makes it perfectly suited for power systems in these regions.

Function

The Siemens 3TB4222-0XP1 functions as an electrically operated switch that makes and breaks power circuits. When the 240 V AC coil is energized, it creates a magnetic field that closes the main power contacts, allowing current to flow to the connected load. Simultaneously, the auxiliary contacts change their state (NO closes, NC opens), which can be used to provide feedback to a Programmable Logic Controller (PLC) or to control other devices in the circuit. When the coil is de-energized, the contacts return to their original position, safely interrupting the power flow.
