THREE PHASE CONTROL PANEL WITH CONTACTOR, RELAY & MCB ELECTRICAL TYPE
1. Direct - Online Control Panel
Direct - Online Starters are the simplest form of motor starter for starting induction motor and these starters basically consist of MCB / Circuit Breaker, Contactor and an overload relay for protection, electromagnetic contactor which can be opened by the thermal overload relay under fault conditions. Typically, the contactor will be controlled by separate start and stop buttons, and an auxiliary contact on the contactor is used, across the start button, as a hold in contact. i.e. the contactor is electrically latched / closed while the motor is operating.
Advantage:
2. Star Delta Control Panel
Start-Delta starters are the most common starters used widely to start AC motors. In these starters the starting current is controlled by applying reduced voltage, which is achieved by connecting motor winding in “Star” mode. Theoretically the current is reduced by a factor of 1 / 3 times and once the motor attains it's normal running stage, full voltage is applied to the motor by changing the connection to “Delta” mode and remains in the same stage till the motor is stopped.
