De contactor vormt de verbinding tussen de stuurkring en de vermogenkring van een schakeling. De hoofdcontacten zijn robuuster uitgevoer en schakelen het hoofdstroomcircuit. De hulpcontacten, die in het algemeen kleinere stromen voeren, zijn lichter geconstrueerd en hebben een functie in het stuurstroomcircuit.
A contactor has three components. The contacts are the current carrying part of the contactor. This includes power contacts, auxiliary contacts, and contact springs.
The electromagnet (or coil) provides the driving force to close the contacts. The enclosure is a frame housing the contacts and the electromagnet. When a relay is used to switch a large amount of electrical power through its contacts, it is designated by a special name: contactor. Contactors typically have multiple contacts, and those contacts are usually (but not always) normally-open, so that power to the load is shut off when the coil is de-energized. How contactors work presented by Katie Rydzewski for Galco TV.
Buy the items featured in this video at 800. Motor Control Contactors. We offer a full line of versatile and robust contactors for both IEC and NEMA applications. Our IEC contactors offer AC and DC control.
They are environmentally friendly, versatile, and flexible. Een contactor is een relais dat naast contacten voor de stuurstroom ook hoofdcontacten of vermogencontacten heeft, waardoor de contactor de verbind. Contactor definition, a mechanically operated switch for continuously establishing and interrupting an electric power circuit. Application areas and power ratings are the two main factors that differentiate relays from contactors though both styles of devices may use the same basic swit. With a wide range of power contactors for switching motors, we can cover many different applications up to 2kW.
