MaxSG Switchgear ABB
MaxSG switchgear is a further continuation in the development of
innovative products from ABB, a world-wide leader in development
and production of low voltage switchgear. MaxSG is industrial duty
equipment built to ANSI standards. MaxSG is designed to use 100%
rated Emax circuit breakers and follows the vision of ABB products
in providing customers with advanced solutions to meet the needs
associated with the mechanical, electrical and thermal stress of
today's manufacturing environment. The MaxSG Metal-Enclosed Low
Voltage Switchgear offers many advantages that include: Modular
frame arrangements Optional barriers for increased personnel
protection Efficient and flexible designs Standard connections
to a full range of ABB products MaxSG is available with the
following nominal ratings:
 |
600Vac max |
|
|
5000Aac max |
|
|
50/60 Hz |
|
|
2200Vac RMS Dielectric |
|
|
125kA Symmetrical Short Circuit Withstand Rating |
|
|
Seismic Qualification Zones 1 -4 |
|
MaxSG can accommodate
four Emax Power Circuit Breaker frame types:
E2 1200-1600A: B-A
N-A
E3 1200-2500A: N-A, S-A, H-A, V-A
E4 3200-3600A: S-A, H-A, V-A
E6 4000-5000A : H-A, V-A
ABB MaxSG switchgear and the use of these breakers will allow a
full range of selectivity, coordination, and short circuit
withstand capability.
MaxSG vertical sections are offered in 23.6" (600mm), 31.5"
(800mm), and 39.4" (1000mm) widths and will allow four 2000A
circuit breakers to be placed in one vertical section maximizing
power supply capability and minimizing floor space. In addition
MaxSG offers depths of 65"(1650mm) and 75" (1900mm) to provide
maximum available cable area.
ABB MaxSG switchgear and Emax circuit breakers have been
designed and conformance tested to meet and exceed the industry
requirements of ANSI C37.13, C37.16, C37.17 and UL 1066 for the
breaker elements and ANSI C37.20.1, C37.51 and UL1558 for the
switchgear assembly.
MaxSG and ABB will fill the customer's needs from general
application through a full range of special applications including
electrical protection, transfer/coordination, and and extreme
environmental applications.
