How many types of contactors are there?
There are different types of contacts in a contactor, and they are; auxiliary contact, power contact, and contact spring. The power contact has two types that are; stationary and movable contact.
What are magnetic contactors?
Magnetic contactors are the same as the electrical relays which are used in a number of electric motors. Magnetic contactors are used in the electric motors to balance the change in frequency of the motor or the state of the motor which can be termed as the switching of the motor from ON and OFF state.
What is a motor contactor?
A contactor is a special type of relay used for switching an electrical circuit on or off. They are most commonly used with electric motors and lighting applications.
What is an IEC contactor?
These contactors can protect your other devices while delivering the performance you expect. IEC Contactors. Our IEC contactors offer AC and DC control. They are environmentally friendly, versatile and flexible. These contactors can protect your other devices while delivering the performance you expect.
What is the main function of contactor?
A contactor is an electrically-controlled switch used for switching an electrical power circuit. A contactor is typically controlled by a circuit which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch.
What is A1 A2 on contactor?
What Do A1 and A2 Mean on a Contactor? A1 and A2 on a contactor typically refer to either end of the electromagnetic coil assembly. Most contactor manufacturers use A1 and A2 to designate the two terminals connecting electrical power to the contactor’s magnetic coil.
What is A1 A2 in contactor?
What is IEC and ANSI?
In the U.S. and in the rest of the world, there are two prevailing standards bodies: the International Electrotechnical Commission (IEC) and the American National Standards Institute (ANSI). ANSI is the prevailing standard in North America and some select regions, while IEC prevails in much of the rest of the world.
What is NEMA vs IEC?
NEMA caters to large-sized devices in North American Markets only. IEC ratings are for more compact devices in the global market. IEC ratings react faster to overloads while NEMA ratings withstand short circuits. IEC devices are safe to the user, while NEMA devices require safety covers.
