for hazardous locations • Sealed for
protection against corrosion, water, dust,
and oil as dened in NEMA 1, 3, 4, 12,
and 13 and IP67 • Complies with ATEX,
IECEx, and UL/CSA regulations • Simple
installation • Extensive switch options and
actuator styles
Benets: To comply with explosion-proof
requirements, the GSX has ame paths
within the housing, which cool exploding
gases below the ignition temperature
before they reach explosive gases
surrounding the housing. Flame paths
are (1) an extended plunger between
the switch cavity and head and (2) the
cover-housing threads on the front of the
switch. Potential applications include
gates, doors, access panels, and/or
cages on machinery in hydrocarbon
refining, chemical processing, agricultural
equipment, food processing, and grain
elevators.
