Installation & Maintenance Information
SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE
APPlication
STANDARDS:
ICI KITs A, B & C are used as circuit breaker, starter and contactor
operators. They are used in panels and enclosures in areas made
hazardous due to the presence of flammable vapors, gases or
combustible dusts. ICI KIT A is typically used for 250-400A Frame
breakers were more leverage is required to compensate for a higher
actuation force. ICI KIT B is used for 150A Frame and lower breakers and
ICI KIT C is used for operating a starter/contactor reset button. ICI KITs
A, B & C are suitable for use indoor or outdoor.
•
•
•
ICI KITs A, B & C meet the ATEX/IECEx directive and are certified by
ETL. Operators have the following classification: II 2 G Ex d IIB+H2 Gb
and II 2 D Ex tb IIIC Db. ICI KITs A & B operators have an IP66 rating and
ICI KIT C has a IP64 rating.
When operators are to be installed in equipment, refer to installation
instruction sheet that came with that equipment for proper installation.
To avoid the risk of fire, explosion, or electric shock: Electrical
power must be off before and during installation and maintenance.

Remove guards, indicating plates, outer locknuts, etc., to enable
barrels to be threaded into the enclosure. Leave final locknut on
barrel for mounting.
Thread barrel assemblies into drilled and tapped holes 3 /4-14
NPSM from behind so they protrude to the enclosure front.
Adjust length of barrel protrusion and thread inner locknut tightly
against inside wall for mounting.
Replace guards, indicating plates, outer locknuts, etc.
WARNING
To avoid explosion: clean both ground-joint surfaces of body and cover
before closing. Dirt or foreign material must not accumulate on flat
ground-joint surfaces. Surfaces must seat fully against each other to
provide a proper explosionproof seal.

1.
Regular inspections should be made. A schedule for maintenance
check should be determined by the environment and frequency of
use. It is recommended that it should be at least once a year.
2.
Perform visual, electrical, and mechanical checks on all
components on a regular basis.
50.8
2.00
• Electrically check to make sure that all connections are clean
and tight, and that contacts in the components make or break as
required.
• Mechanically check that all parts are properly assembled, and
operating mechanisms move freely.
