ASCO 7000 Series Automatic Transfer Bypass-Isolation Switches 150-600 Amperes ASCO Now Offers Drawout Transfer Switch Design From 150 to 3000 Amperes Automatic Transfer BypassIsolation Switches are available in open transition, closes transition and delayed transition designs, plus each configuration is available with a service entrance rating. The bypass isolation feature allows the power transfer switch to be inspected, tested and maintained without interrupting power to the load. The 7000 Series also includes a Microprocessor Based Controller, which represents the most advanced digital based microprocessor control panel in the industry. It includes, as standard, all of the voltage, frequency, control, timing and diagnostic functions required for most emergency and standby power applications. 800-1200 Amperes 1600-3000 Amperes Features • Draw out design for power transfer switch for ease of maintenance • Allows bypass-isolation of transfer switch without load interruption • Both transfer switch and bypass switch have identical ratings • Heavy-duty mechanical interlocks prevent undesirable operation • Bypass contacts carry current only when in bypass mode • Bypass and isolation handles are permanently mounted. The bypass switch has dead front, quick-make break operation for transferring loads between live sources • Redundant LED’s and mechanical indicators provide guaranteed indication of transfer and bypass switch positions • Bypass switch is fully rated for use as a manual three position transfer switch for emergency load transfer when transfer is isolated for maintenance • Bypass and isolating function is simple, requiring a total of two operating handles. No toggle switches, push-button or levers are required for operation. • UL Listed to 1008 Transfer Switch Equipment and CSA Certified to CSA 22.2 No 178-1978 Automatic Transfer Switches. ASCO 7000 Series Automatic Transfer Bypass-Isolation Switches Transfer Switch Draw out Features • Automatic secondary disconnects remove all control power as transfer switch is withdrawn • Draw out carriage provides for easy transfer switch maintenance and/or removal Bypass-Isolation Transfer switch secondary disconnects • Self aligning jaws provide positive connection of bus connection during reconnection of transfer switch Bypass-Isolation Transfer Switch self aligning power jaws Transfer-Bypass Status Panel In addition to mechanical indicators to show bypass switch position and whether the transfer switch is in the connected, test or isolated position, a transfer/bypass LED status panel is also provided. Eleven LED Indicators embedded on a one-line diagram of the transfer and bypass contacts, source availability and load connection status : Bypass Transfer Status Panel Publication 3096 R3 •Bypass to normal •Bypass to emergency •Load connected to normal •Load connected to emergency •Transfer switch in connected position •Transfer switch in test position •Transfer switch not in automatic (flashing) •Normal source available •Emergency source available •Load connected •Lamp test button •Engine start switch for emergency transfer initiation when transfer switch is isolated or removed for maintenance . . 800-800-ASCO www.ascopower.com 50 Hanover Rd, Florham Park, New Jersey 07932 U.S.A July, 2008 Printed in the U.S.A.
