ASCO power Technologies(ASCO) provides the solu-tions to handle the transferof critical loads to emer-gency sources reliably andwith state of the art prod-ucts. Using ASCO productscan mean the differencebetween a minor inconven-ience and a major catastro-phe.

2 You ll find ASCO PowerTransfer Switches whereverthere is a critical load to flexibility in powerswitching is a must, ASCO offers a variety of product solutions to meet virtuallyevery application require-ment, including distributedgeneration s why the 7000 SERIESis available in open, delayed,closed and closed soft loadconfigurations.

3 Conventional two-position transfer configuration, plus closed and delayed transition modes of operation. All configurations available with either automatic or non-automatic control. UL listed to 1008 Transfer Switch Equipment & CSA certified to CSA AutomaticTransfer Switches. Qualified and certified to IEC 60947-6-1, CE marked(optional). (Limited to certain accessories.) Rated up to 600 VAC, 30 through 4000 Amperes. Reliable and field proven solenoid operating mechanism. High withstand and close-on ratings including short timewithstand current rating for optimum flexibility in circuitbreaker coordination (600-4000 Amperes).

4 Solid, switched, or overlapping neutral conductor power Transfer Switches are the standard of theindustry. High speed transfer of loads between alter-nate sources of power , regardless of ampacity size, isachieved by a reliable, field proven solenoid operatingmechanism. When combined with a programmablemicroprocessor controller with keypad and LCD display,they offer the most advanced method of transferring alltypes of loads, such as motors, electronic drives, UPS'sand microprocessor based systems. 7000 SERIESP owerTransfer Switches are available open or enclosed, inampacity sizes from 30 through 4000 Amperes with thelargest selection of optional accessories offered any-where.

5 All switching configurations are available with anintegrally mounted bypass-isolation switch and/or ratedfor use in service entrance applications. Front replaceable main and arcing contacts (800-4000 Amperes). Programmable microprocessor controller with keypad andLCD display. Centrally located terminal block for customer control connections (260-4000 Amperes). 16mm, Industrial grade control switches and indicating lights. Switch position LED indicators and source acceptability lights. Standard ground conductor connections. Four auxiliary contacts, two contacts closed when switch is in normal position and two contacts closed when switch is in emergency position.

Applications include older style variable frequencydrives, rectifier banks, and load management applications.

7 Available in 150 through 4000 Amperes. Utilizes reliable, field proven solenoid operating mechanisms. Mechanical interlocks to prevent direct connection of bothsources. Indicator light (16mm, Industrial grade type LED) for load disconnect position. Adjustable time delay for load disconnect Transition Transfer SwitchingASCO Automatic Closed Transition Transfer Switches featuremain contacts that overlap, permitting the transfer of electricalloads without power interruption. The switch transfers in amake-before-break mode if both sources are within acceptableparameters. Control logic continuously monitors source conditions and automatically determines whether the loadtransfer should be open (conventional non-overlap mode) orclosed transition.

8 Available 150 through 4000 Amperes. Closed Transition Transfer within 5 electrical degrees is achievedpassively, without control of engine generator set. Therefore, noadditional control wire runs are required between the ATS andengine generator set governor. Plus, protective relaying maynot be required under normal operation since the contact over-lap time is less than 100 milliseconds (consult your local utilityon protective relay requirements).Failure to synchronize indication and extended parallel timeprotection is built-in to all 7000 SERIES closed transition controls to prevent abnormal 2:Four pole, Closed Transition Transfer Switchrated 1000 Amperes in Type 1 SERIESP ower Switching SolutionsNon-Automatic Transfer SwitchingASCO Non-Automatic Transfer Switches are electricallyoperated units which are operated with manual controlswitches mounted locally or at remote locations.

9 Sizes from 30 through 4000 Amperes. Microprocessor based controller provides for additionof optional accessories. Controller prevents inadvertent operation under lowvoltage conditions. Low control circuit operating currents allow for longline runs between remotely mounted manual controlswitches and the transfer switch. Source acceptability lights inform operator if sourcesare available to accept load.

10 The bypass and isolation features allowthe primary automatic transfer switch to be inspected, tested,and maintained without any interruption of power to the also provide redundant power transfer in the event theATS is disabled or removed from service. Available 150 to 4000 Amperes. Allows bypass-isolation without load interruption. Bypass switch and transfer switch have identical electrical ratings. Heavy duty mechanical interlocks prevent undesirable operation. Bypass contacts carry current only during bypass mode. Transfer switch is drawout design for ease of maintenance. Bypass and isolation handles are permanently bypass switch has dead front quick-make, quick-breakoperation for transferring of loads between live sources.
