CDC17 series AC contactors are suitable for use in circuits with rated
voltage up to 660V AC, 50Hz or 60Hz, and rated current up to 95A.

Used for making, breaking, frequently starting and controlling AC motors,
when combined with an auxiliary contact block, air delayer and machine-interlocking
device etc, these products form delay contactors, mechanical interlocking contactors
and star-delta starters.

Combined with thermal relays, electromagnetic starters are formed. These
contactors are produced according to IEC947-2, VDE0660 and BS5452 standards.
