interlock for 3 phase motor protection ?
Answers were Sorted based on User's Feedback
Start Limitation: It is the limitation from the Motor
Design side. There is a limitraion for motor from No.of
Consecutive hot Stat and Consecutive Cold Stat according to
motor themal withstandabulity.
Start Inerlock: It is permissiveness given to start the
motor from its protection or proceess interlocks.Example
motor cooling blowers should be on before motor starts.

Start limitation means no. of start this is bercause if
consecutively u start the motor the motor got heated&
thermal conductivity will dec. .not goo for its health.
Start interlock means
frequency,voltage& powerrequirement we can control by
different relay so. after fullfilling those constraints
only it should start for giving poptimal performance.
