48 EVOLUTION SERIES E9000 MOTOR CONTROL CENTER
Electronic overload for circuit breaker and
fused controllers
The tripping current is 120% of the dial setting.
For continuous-rated motors with a service factor
of 1.15 to 1.25, set the dial to the motor full-load
current. For continuous-rated motors with a
service factor of 1.0, set the dial to 0.9 of the motor
before energizing.

IEC style overload relays
C2000 contactor CLNCJ type RT overload relay
for 1/2X starter
Provide short-circuit protection in accordance with
NEC Article 430 or CE Code Part 1.
Tripping current is 120% of Dial setting. Motors
with 1.15-1.25 service factor, set dial to motor
FLA Motors with 1.0 service factor, set dial
to 0.9 motor FLA.

Opening of the branch-circuit protective device
may be an indication that a fault current has been
interrupted. To provide continued protection
against £re or shock hazard, examine all current-
carrying parts and other components of the motor
controller and replace any damaged components. If
heater burnout occurs, the complete overload relay
must be replaced.
