ASCO 7000 Series Power Switching Solutions

Non-Automatic Transfer Switching

ASCO Non-Automatic Transfer Switches are electrically operated units which are operated with manual control switches mounted locally or at remote locations.

•Sizes from 30 through 4000 amperes.

•Microprocessor based controller provides for addition of optional accessories.

•Controller prevents inadvertent operation under low voltage conditions.

•Low control circuit operating currents allow for long line runs between remotely mounted manual control switches and the transfer switch.

•Source acceptability lights inform operator if sources are available to accept load.

•Standard inphase monitor can be activated for transferring motor loads.

Notes: 1) All values are available symmetrical RMS amperes and tested in accordance with the withstand and close-on requirements of UL 1008. See publication 1128 for more information on withstand and close-on ratings for ASCO transfer switches.

2)Application requirements may permit higher withstand ratings for certain size switches. Contact ASCO for guidance if available short circuit current exceeds the WCR ratings shown.

3)“Any” breaker ratings are based on 1.5 cycles for 30 - 230 amp & 3 cycles for 260 - 4000 amps. Applicable to breakers with instantaneous trip elements.

4)Short time ratings are provided for applications involving breakers that do not have instantaneous trips for system coordination.

5)Short time rating applicable to transfer switch design only.

6)Optional front connected service limited to 85,000 amps for specific and any breaker rating.
