SIEMENS

Contactor relays and miniature contactors

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 produces a wide range of contactor relays that are suitable for various industrial applications. These relays are known for their durability, high performance, and advanced features such as overload and short-circuit protection.

SIEMENS

Contactor relays and miniature contactors

Contactor combinations offered by Siemens are pre-assembled configurations of contactors and auxiliary components. These combinations are designed to simplify installation and reduce wiring efforts. They provide a convenient solution for controlling and protecting motors or other electrical loads. Siemens offers a wide range of contactor combinations with different sizes, ratings, and features to meet various application requirements.

Contactor assemblies for star-delta (wye-delta) starting

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.

Reversing Contactor Assemblies

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.

Siemens offers a range of reversing contactor assemblies with different specifications and features to meet the specific requirements of different industries. These assemblies typically consist of contactors, overload relays, and interlocking mechanisms.

The contactors are responsible for switching the motor currents on and off, while the overload relays protect the motor against overcurrent and overheating conditions. The interlocking mechanisms ensure that the motor cannot operate in both forward and reverse directions simultaneously, preventing any potential damage.
