Contactor relays and miniature contactors are electrical devices manufactured by Siemens.
Contactor relays are typically used in control circuits to control the operation of electric motors or other electrical loads. They are designed to handle high currents and voltages and provide a reliable switching mechanism.
Contactors consist of a coil, contacts, and an arc extinguishing system. When the coil is energized, it creates a magnetic field that attracts the contacts, closing the circuit and allowing the current to flow to the load. When the coil is de-energized, the contacts open, interrupting the current flow.

Siemens offers contactor assemblies specifically designed for star-delta (wye-delta) starting applications. These assemblies are used to reduce the inrush current and torque when starting induction motors connected in a star-delta configuration.
The contactor assemblies for star-delta starting consist of multiple contactors, typically three or six, and auxiliary components like timers and control relays. During the starting sequence, the motor is initially connected in a star configuration, which reduces the voltage applied to the windings and limits the current. After a specified time delay, the contactors switch the motor connections to a delta configuration, enabling full voltage and maximum torque for normal operation.
A Reversing contactor assembly, provided by Siemens, is an electrical control device used in various applications to control the direction of rotational motion of motors. It is specifically designed for reversing the direction of motor rotation, allowing for forward and reverse operation.
