LC1-D series AC contactors are suitable for use in 50Hz circuits with rated
voltage up to 660V, and rated current up to 95A. These products are used for
making, breaking, frequently starting and controlling AC motors.

Combined with an auxiliary contact block, timer delay, machine interlocking
device etc, these items become delay contactors, mechanical interlocking
contactors and star-delta starters. When combined with a thermal relay,
they combine into an electromagnetic starter.
