Normally refers to a poly phase motor starter that monitors current draw in all three legs and interrupts all legs. the most popular use "heater-melting alloy" technique, magnetic current monitoring is also popular but IMHO thermal alloy offers superior protection in high starting load applications.

What is the use of 4-point starter in motors?

The four-point starter eliminates the drawback of the three-point starter. In addition to the same three points that were in use with the three-point starter, the other side of the line, L1, is the fourth point brought to the starter when the arm is moved from the "Off" position. The coil of the holding magnet is connected across the line. The holding magnet and starting resistors function identical as in the three-point starter. * The possibility of accidentally opening the field circuit is quite remote. The four-point starter provides the no-voltage protection to the motor. If the power fails, the motor is disconnected from the line.


Can a 125 HP 3 phase 460 volt saw be started with an across the line starter?

CAN and WILL BE ALLOWED TO are different questions. Whether or not the motor CAN be started across the line will depend on the available short circuit current (SCC) at your location on the local utility's power distribution grid, and the rating of your service transformer. Check with your utility company. It may be possible to start the motor across the line, based on the transformer rating, but if there is not enough SCC, the utility will not allow you to connect the load without a starter or variable frequency drive system.

What is the necessity of the starter in fluorescent lamp?

When line voltage is applied across the starter, it closes a circuit, connecting the filaments at the ends of the bulb in series so they heat up. Once the Mercury in the lamp is vaporized, the starter breaks the filament circuit, and the ballast provides a voltage pulse to start the current flow down the length of the tube, lighting it. While the bulb is lighted, the voltage across the starter is low and it does not energize the filaments. When you see a fluorescent lamp flashing, the bulb is worn out and the starter keeps vainly trying to start it. Eventually the starter will wear out and will need to be replaced also. Newer fluorescent fixtures have lamps and ballasts that do not require a starter.
