Full Load Vacuum Interrupters Ratings: 15kV through 230kV Ratings A: 600, 1200, 2000 Amperes

The Turner TECO-Rupter is a vacuum circuit interrupter that is offered as an attachment to the Turner switch, as well as designs of other switch manufacturers. It is offered in three (3) basic configurations and can be attached to vertical break, side break, hookstick and some center break switch designs. The configurations are as follows:

1. Loop or parallel break - Normally these are single vacuum contact devices that can interrupt up to 2000 Amps, up to 230 kV, under paralleled conditions, (i.e., rated voltage exists on both the hinge and jaw of the switch immediately after the interrupter is opened.) The transient recovery voltage must not exceed 30 kV for the single contact. More contacts can be added to address higher recovery voltages; consult factory.
2. Line/bus charging/line sectionalizing interruption/transformer magnetizing current interruption - A full voltage multiple stack interrupter may be utilized from 15 kV through 230 kV for interruption of line or bus charging currents and transformer magnetizing currents up to a value of 70 Amps at 0% power factor, capacitive or inductive. The nameplate operating current of the switch is not a factor in the application of this device.
3. Load interruption - A full voltage multiple stack interrupter may be applied from 15 kV through 230 kV for interruption of actual load current at 70% power factor.

The TECO-Rupter is only in the circuit during the opening sequence, (normally one [1] to two [2] seconds in duration.) Also, contact test studs on the exterior of the enclosure allow you to independently Hi-Pot each vacuum contact when the actuating arm is in the open position at 30 kV.
