PROTECTION RELAY
The ECAI00-II electronic three-phase relays are specially designed for the protection of air conditioning and refrigeration compressors
and ventilation motors from the causes of current, voltage and power failures, all with enhanced reliability and with connectivity."
knowledge of overload relays and associated
machinery should perform the installation, starting
up, and maintenance of the system. Adhere to all local
and national electric codes. Disconnect all electrical
power at the source prior to any installation or
maintenance work. Failure to comply could result in
equipment damage, personal injury, OR even death.

over a flat surface panel and mount it using (2)
#8 x 1/2" screws
Recommendation for Flat Surface Mounting:
Make two (2) holes (5/32") on panel surface
before installing.Refer Section 5 for
dimensions.
CAUTION:
Check that the rated voltage and current of the
selected
ECAI00-II
model corresponds to the line voltage
and motor current.
Avoid overtightening M2.5 screw terminals during wiring of
connections. Torque max. 4.5 lb-in (5.18 kgf-cm)

Feed the the three phases going to the motor through the three
current sensing holes. Using less than three wires may cause
undesired current unbalance
ATTENTION:
Any accidental or intentional change of
setting knob positions after overload asjustment will cause
variations in the ECA100-II's protective performance from
previous setup. In this case, repeat procedure for ECAI00-II
