A magnetic starter is a specially modified contactor, which is designed to start electric motors, electrical circuits and ensure their continuous operation. A high-quality switching device is highly reliable, but requires periodic replacement.
Modern starters
Even the highest quality magnetic starter price which will be quite high may fail. This is due to the fact that this device is electromechanical and contains moving parts. They are the ones that fail in the first place.
Modern starters are unified in size and provided installation methods. Any such device can be conveniently and quickly replaced using the DIN rail mounting option.
Installation of such starters is carried out in standard electrical panels. This ensures a high degree of safety in the use of devices, protection of personnel from possible electric shock, as well as protection of the starters themselves from adverse external influences.
Thanks to this, it is possible to place leaky starters in specially equipped panels located outside the premises. This arrangement is especially useful when using these devices to turn on and control networks of high-power lighting fixtures.
Additional functions
In addition to its main function, the starter can also be used to turn on the reverse mode of operation of the electric motor, changing the direction of current flow. In addition, modern starters are equipped with thermal relays and various residual current devices. In the first case, such a contactor opens the circuit, protecting the electric motor from overheating and damage.
In the second case, the starter protects the motor or any other connected electrical appliances and from voltage surges. Starters installed on three-phase electrical devices can open the circuit if one of the phases is interrupted.
The starter can be purchased only from trade enterprises specializing in the supply of low-voltage equipment. In addition, any industrial wholesale electrics is much cheaper than buying in a retail network. Retailers offer only certified products of proven quality and performance and cherish their reputation as reliable suppliers.
