Medium Voltage Contactor - 7.2 kV Class

Motortronics 7.2kV Class, ‘Non-Latching’ (C) and ‘Latching’ (CJ) Series of medium voltage three-phase indoor vacuum contactors can be used in power systems with a rated voltage of up to 7.2 kV and can be used for continuous AC operating currents of up to 400, 630 or 800 amperes. Control power for the design is 120VAC, with an external interposing relay consisting of DC-rated contacts required to operate the closing and opening circuits of the contactor (Latching models CJ).

Non-Latching (C) - uses constant-on electromagnetic coils to close, and hold closed the vacuum bottle contacts. When the power to the electromagnetic coil is removed, the vacuum chamber contacts spring open (termed as; electrically held contacts or non-latching contacts). Latching (CJ) - uses separate coils and mechanisms to both close and open the vacuum bottle contacts (termed as; mechanically held or latching, contacts).
