1. How does a reversing contactor operate?
A reversing contactor refers to the contactor that reverses a 3-phase motor using contactors. You have to run a single set of wires straight via a single contactor, and a parallel set of wires via another contactor where you interchange one set of wires. As the motor is started, the motor rotates in a single way, and when the contactor is started, the motor turns in the opposite direction.
2. What is the mechanism of reversing motor starter?
The reversing motor starter is created in such a way that it reverses the shaft rotation of a 3 phase motor. This is achieved by interchanging any among two line conductors that deliver the motor load. The reversing magnetic motor starter includes a forward and reverse starter as components of the assembly. The electrical, as well as the mechanical interlocks, are offered only the forward or the reverse starter can be applied at any given time but they cannot be engaged at the same time.
3. What does a reversing starter refer to?
This refers to a 3 phase starter motor controller that consists of two motor contactors. It does not use the contactor to open and close the power circuit so as to turn the motor on and off, but it uses a forward and reversing contactors in controlling the motor directions.
4. What does an auxiliary contactor do?
Contactors are normally classified in load and auxiliary contactors. The load contactors consist of extreme switching capacity. These are normally used as the main contactors as they can handle loads of up to 600 A /AC1. The auxiliary contactors are just designed for switching currents which are lower ratings to up to 6 A. Among the auxiliary contactors count are the timer relays and the safety relays. Basically, an auxiliary contactor is a normal low power relay but designed like a normal contactor and when used in combination with another contactor it is referred to as auxiliary contactor to imply that it is not used to switch loads but it is used to activate or deactivate or control the operation. The auxiliary contactors normally consist of contacts and have no main contacts.
5. What is the main operation of a contactor?
The load contactors are normally with extreme switching capacity which normally is used as the main contractor. It is installed to handle loads of up to 600 A /AC1.
6. Why should I use an auxiliary contactor?
Normally an auxiliary contactor is a normal contactor just like a low power relay if it is used in combination with another contactor is known as an auxiliary contactor in order to identify its use as it is not used for switching loads but it is used for activating and deactivating or controlling function. This means that auxiliary contactors consist of only auxiliary contacts and have no main contacts.
