12 Kv Class Vacuum Contactor

12kV Class - 400, 630 and 800A:-

 Our Series 12kV Class 400, 630A and 800A, ‘Non-Latching’ Series of medium voltage three-phase vacuum contactors can be used in power systems with a rated voltage up to 7.2 kV and can be used for continuous AC operating currents of uptot 800 amperes. Control voltage for the contactor is 110~120VAC or 220~230VAC*.

This Series 12kV Class 400A, 630A and 800A Class contactors are non-latching and use 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).
