What is meant by main contact and auxiliary contact in magnetic contactor?
Wiki User
∙ 12y ago
The main contact controls the load current to the motor, whereas the auxiliary contact is part of the control circuit -usually connected in parallel with the 'on' pushbutton switch to maintain the control circuit in the energised state, once the on pushbutton has been pressed.

The main contact in a magnetic contactor is the primary contact used to control the flow of current to the load. The auxiliary contact is an additional contact that is used for signaling or monitoring purposes, such as indicating the status of the contactor or controlling other devices in the circuit.

How will calculate the power of magnet?
The power of a magnet is typically measured in terms of its magnetic field strength, which is usually measured in units of teslas (T) or gauss (G). The power of a magnet can be calculated by measuring the magnetic flux density at a specific distance from the magnet using a gaussmeter or other suitable instrument. The strength of a magnet's field diminishes with distance, so the power of a magnet would also depend on the distance at which the measurement is taken.
What is charge offensive or provocative contact?
Charged offensive or provocative contact refers to physical contact that is intended to be harmful, insulting, or alarming. It can include actions such as punching, shoving, or any other form of physical aggression that is meant to intimidate or harm another person.
What is meant by core saturation?
Core saturation refers to a point in which the magnetic core material of an inductor or transformer becomes fully magnetized to its maximum flux density, limiting any further increase in magnetic flux. When a core is saturated, it can lead to distortion of the waveform, loss of efficiency, and overheating of the component.
Why does in an electrical plug the earth pin is longer than other two...what is its main function?
The longer earth pin is meant to make contact first and break contact last when plugging and unplugging, for safety reasons. Its main function is to provide a path for electrical current to flow to the ground in case of a fault, helping prevent electric shocks or fires.
What is meant by the phrase trans ocean?
The phrase trans ocean is meant to mean across the ocean. Trans ocean is meant to be the same as transocean, which is not a word but a shorter version of transoceanic, to which it is meant to have a similar meaning.

What is meant by magnetic permeability?
All materials are magnetized when placed in the magnetic field . The material magnetized by the effect of a magnetic field is called magnetic permeability.
What is meant by magnetic shell?
give Langevins theory of paramagnetism?
What is meant by the term diamagnetism?
Diamagnetism is weak repulsion by a magnetic field.
What is meant by mutualism?
conection between two or more magnetic circuits magnetically with out any electrical connection .i.e.'flux linkages are there inbetween the magnetic circuits.
What is meant by mutual coupling?
conection between two or more magnetic circuits magnetically with out any electrical connection .i.e.'flux linkages are there inbetween the magnetic circuits.
What is meant by a magnetic circuit?
Lines of force go from a North pole of a magnet to the South pole external to a magnet, and through the magnet itself. This path is the magnetic circuit. It may be diverted and distorted by magnetic materials nearby.
How do you contact Philanthropoligists?
There is no such thing as a Philanthropoligist. Perhaps you meant "philanthropist"?
What are the differences between contact and agreement?
None, if you meant "contract".
What is meant by tangent in physics?
when a magnetic substance in placed i two uniform magnetic field (b) and (h) which are mutually perpendicular and coplanar to each other. then the magnetic field intensity of magnetic field of b which making angle θ with h is tanθtimes of h.mathamatically B=tanθxH.
Whats meant by radial magnetic field?
A radial magnetic field ensures that the plane of the coil (rotating within the magnetic field, in say a DC motor) is always flat within the external magnetic field ensuring maximum torque in (nearly) all positions. Hope this helps!
What is meant by the English verb 'shall'?
The verb 'shall' is most often an auxiliary verb.Example: I shall plant the rose bushes tomorrow.
