ReliaGear® UL 1558 low-voltage (LV) switchgear, new from ABB Electrification Products division, features 100 percent-rated Emax 2 circuit breakers with embedded logic capabilities that make the switchgear safer and more compact, flexible and reliable.
  • New switchgear features Emax 2 circuit breakers for greater safety, compactness, flexibility, reliability
  • ABB launched ReliaGear UL 1558 LV switchgear as part of ABB’s rebranding of its power distribution equipment portfolio: All medium- and low-voltage solutions are branded as ReliaGear for standard equipment and SafeGear® for arc-resistant equipment. 
  • ReliaGear UL 1558 LV switchgear has been tested to UL, CSA and American National Standards Institute (ANSI) standards, and is ANSI C37.20.1 compliant. The equipment incorporates UL 1066-compliant Emax 2 air-insulated circuit breakers, which offer among the most advanced data communications and automation power-distribution technology in the world. These circuit breakers enable ReliaGear UL 1558 LV switchgear to improve safety, occupy less space by reducing size, adapt more readily to changing applications by being modular and increase service life by as much as six times for greater reliability.
“ABB’s new ReliaGear UL 1558 LV switchgear offers a turnkey solution for power distribution in critical power applications,” said Oscar Moreno, local switchgear product manager, ABB Electrification Products division. “The advanced technology of Emax 2 air-insulated circuit breakers includes expanded communications capabilities and embedded logic capabilities that allows ABB’s switchgear to be more flexible in design and more intelligent than our competition.”

“Smart” features enable ReliaGear UL 1558 LV switchgear to be integrated fully into smart grids, buildings and industrial plants. Some of these features include a synchro-check function integrated into the trip unit, automatic transfer scheme options, simultaneous or redundant communications, seven industrial protocols, a power controller function, a network analyzer, and generator protection functions. ReliaGear UL 1558 LV switchgear also offers among the smallest footprints in the industry, with the main-tie-main breaker contained in one section and widths ranging from 18-38 inches and section depths of 72 or 84 inches.

Features of the ReliaGear UL 1558 LV switchgear that foster safety and reliability include safety shutters and insulating barriers between sections and around the bus compartment to isolate it from the cable compartment. Additionally, no ventilation is required in the front of the equipment. Optional safety features include arc flash detection, arc mitigation solutions and remote operation of circuit breakers with the Ekip Link system.

ReliaGear UL 1558 LV switchgear also features field-interchangeable trip units: Ekip for distribution protection and Ekip G for generator protection. Rogowski coils eliminate the need to replace current transformers when adjusting the circuit breaker current rating. Other features include standard built-in top and bottom horizontal wireways for control wires with no additional height and standard white paint mounting pans provided for each instrument compartment.
