Push Button and Operator Interface - Type B and 30 mm Control Stations
Types K, SK, KX, and T — 30 mm Reed Contact Blocks & Hazardous Location Information
In hazardous locations, it is not always required to use explosion-proof
equipment like the Class 9001 Type BR control stations. Knowing what
type of hazardous location exists will permit you to select the most eco-
nomical solution to your application. If you're not sure what type of haz-
ardous location exists, the “Summary of Classification” chart may help.
If not, contact your local electrical inspector. When you know what
class, division, and group(s) exists, see the table in the lower lefthand
corner of this page for what Square D has to offer.

Class
An intrinsically safe system requires either a Class 8501 Type TO or NY2 barrier relay or an
intrinsically safe barrier to restrict the energy available in the area classified as a hazardous
area to a level less than that required to cause an explosion. In an intrinsically safe system,
any non-illuminated Class 9001 operator or control station with standard contacts can be
used. No illuminated operators, except the Class 9001 Type KP44 intrinsically safe pilot light,
may be used.
Any Class 9001 Type K, SK or KX operator can be used in an area classified as Class I, Divi-
sion 2 hazardous locations.
1. Only logic (KA40 series) or power (KA50 series) reed contact blocks are used.
2. All Type K and SK illuminated operators are UL approved for use in Class I Division 2
3. Type KX illuminated operators do not use 4 lamp light modules, or 2 lamp light modules
4. The operators are mounted in Type KY, KYSS, KYAF, SKY enclosures.
Any Class 9001 Type K, SK, or KX operator mounted in a Class 9001 Type KY, KYSS, KYAF,
SKY enclosure may be used, except potentiometer operators.
