What are contactors electromechanical?
A contactor, contactor switch, or contactor relay is a device used to turn on or off an electrical circuit. They belong to the relay family, but the primary distinction is the employment of a contractor in applications with larger current capacities. Motors, lighting circuits, heaters, and other electrical loads commonly employ contractors. A contractor can work alone, as a power control tool, or as a component of a motor starter. Our thorough contractor's guide has further information.
Contactor Specifications
There are various types of contractors, and each type has its own set of specifications based on your application. Some essential specifications are
- AC Contactor or DC Contactor with coils such as 12 V, 24 V, 48 V, 110 V, 240 V, 400 V, and 440 V.
- Reversing or non-reversing functionality.
- AC3 and AC1 categories.
- Contactors with 2 poles, 3 poles, 4 poles, and even 8 and 10 pole variants.
- Various contact configurations.
- IEC standards
What is the purpose of electrical contractors?
Contactors have spring-loaded contacts that may make or break power supply lines to a load and are made to be linked to high-current load devices. To help with arc suppression, these contacts are made to open and close very quickly. As a result, the contractor may interrupt strong motor currents with less damage over a longer life cycle. A contactor is widely used in devices that are regularly turned on and off, and many contactor designs are created for various current needs. Contactors are used in a wide range of applications, from simple light switches to more complicated ones like regulating electromagnets.
How do contractors work?
Contrary to normal relays, contactors electromechanical are made expressly to be connected to high current load devices. A contactor is a switch that can be operated remotely and is used in larger-scale control circuit applications because it is made to switch a significant quantity of electrical power across its contacts. A device is referred to as a contactor if it can switch more than 10 amperes. Additionally, these devices have high coil voltages, which are uncommon in relays.
