B3TF4622

The B3TF4622 is a BRAH Electric aftermarket direct replacement contactor for the Siemens 3TF4622, rated for 45A at 600V with 3 poles and a {coil voltage}V AC coil. It is a three-phase magnetic contactor designed to switch motors and other heavy loads in industrial control panels, with ratings of 20 horsepower at 230 volts, 40 horsepower at 460 volts, and 50 horsepower at 575 volts. The B3TF4622 comes complete with its control coil and with two normally open and two normally closed auxiliary contacts, so it is ready to install as a direct substitute for the original contactor. When the coil is energized, the power contacts close and carry the load current, and when it is de-energized, they open. The auxiliary contacts can be used for control circuit functions such as sealing in a start circuit, interlocking, or signaling. The B3TF4622 is a factory new part, not reconditioned, and BRAH designs it as a drop-in fit, so it uses the same mounting and wiring as the Siemens World Series contactor it replaces and needs no modifications. It is backed by a 2-year warranty. Because the replaced contactor was built in several coil voltages, it is worth confirming the coil voltage and the full part number against your equipment before ordering. This makes the B3TF4622 a practical choice for maintenance teams and panel builders who need to replace an obsolete or failed Siemens 3TF46 contactor and keep a motor starter in service.
