Motortronics 7.2kV Class, ‘Non-Latching’ and ‘Latching’ 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 amperes. Control voltage for the contactor is AC/DC 100~125V or AC/DC 200~230V, including an auxiliary relay with 3 NO and 2 NC contacts.
Non-Latching - 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 - uses separate coils and mechanisms to both close and open the vacuum bottle contacts (termed as; mechanically held or latching, contact).
Rated Voltage: 7.2kV
BIL Voltage: 60kV
Rated Current: 400A
- Latching and Non-Latching: Fixed Mount, Dbl Terminal w/o counter, non-fused, 120VAC control.
