Hazardous locations do not always require the use
of explosion-proof equipment like the Class 9001
Type BR control stations. Selecting the most
appropriate device for the location can save you
money. For more information on the types of
hazardous locations, contact your local electrical
inspector.

The maximum number of logic and/or power reed contact blocks per operator is
as indicated on individual selection tables for standard contact blocks, except:
•
On 3 position selector switches with cams C, D, E, F, G, L, or M, mount reed
blocks on one side only (either side), maximum 2 in tandem.
•
On 4 position selector switches, mount reed blocks on one side only (either
side), maximum 2 in tandem.
•
On joysticks or on Type KR8 or SKR8 push-pull operators, mount reed blocks
on one side only (either side), maximum 2 in tandem.

PUSH BUTTONS AND OPERATOR
INTERFACE
[128] Any Class 9001 Type K, SK or KX operator can be used in an area classified as Class I, Division 2 hazardous locations, if:
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 areas. (Add Form Y243 to single lamp Push-To-Test pilot lights.)
3. Type KX illuminated operators do not use 4 lamp light modules, or 2 lamp light modules other than the transformer type. (Add Form Y243 to single lamp Push-To-Test pilot lights.)
4. The operators are mounted in any NEMA 4 & 13 enclosures.
[129] UL Listed: File E10054(N), CCN NOIV.
[130] 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.
[131] Not for use in pendant stations.
[132] When ordering, add prefix 9001 to the catalog number.
[133] All contact blocks listed below accept #12–18 solid or stranded wire.
[134] The power reed contact blocks can be used with standard industrial relays and starters through NEMA Size 4. Minimum voltage is 5 V and the minimum current is 1 mA.
