FIGURE 2.1.1
Contactors provide input ON-OFF control. An input circuit
breaker disconnects all input power from the cabinet.
Meets National Electrical Code Protection requirements for
single phase, and reversed-phase rotation protection.
587 requirements at 4000 V peak. Up to 150% line voltage
for ½-cycle.
Unit will operate properly with any input phase rotation.
There are no input phase rotation sensitive devices.
An input transformer with an electrostatic shield provides
isolation between the input and output of the system.
All three input phases are equally loaded regardless of
output phase load unbalance.
