Emerson Network Power expands ASCO 7000 Series 600-1200 Amp power transfer switches with 30-cycle rating for larger projects

July 3, 2014

Florham Park, N.J. — Emerson Network Power, a business of Emerson (NYSE: EMR) and a global leader in maximizing availability, capacity and efficiency of critical infrastructure, expands its ASCO® 7000 Series Automatic Transfer Switch and ASCO 7000 Series Bypass-Isolation Transfer Switch family with a 30-cycle rating in a 600-1200 ampacity range.

"This new configuration further increases the choices in cycle ratings available to meet a range of selective coordination requirements, including the majority of lower cycle applications," said Ron Schroeder, director of product management for Emerson's ASCO Power business. It's the latest in a series of product launches that builds on ASCO Power business' leadership in innovation and technology.

The 30-cycle rating in the 600-1200 ampacity range for selective coordination designs has a withstand close-on rating (WCR) of 30 kA at 480V. The withstand close-on rating of an automatic transfer switch is its ability to withstand and close-on short circuit currents with a specific type of over-current protective device, or for a finite period of time. At 30 cycles, the time period is typically 0.5 sec at 60 Hz.

The 30-cycle rating enables 600-1200 amp ASCO 7000 Series Transfer Switches to be specified for larger, more complex projects where the fault current on the emergency system is high, where the breaker instantaneous trip setting is defeated in order to selectively coordinate, or where transfer switches are served by ANSI Switchgear, which also has 30-cycle WCR.

The configuration integrates a new support structure into the robust, core transfer switch design that helps the bus bar withstand the higher dynamic forces generated at 30 cycles, 480V. The 30-cycle rating for the 600-1200 ampacity range is the most recent advance in an ongoing product development program designed to improve performance benchmarks.

ASCO 7000 Series Power Transfer Switches conduct high speed transfers of loads between alternate sources of power, regardless of ampacity. Combined with a programmable microprocessor controller with keypad and LCD display, they offer the most advanced method of transferring all types of loads. They are available open or enclosed, in ampacities ranging from 30 through 4000 amps.
