MOTOR PROTECTION RELAY

ECA100-II MOTOR

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.

ECAI00-II

Place

ECA500-II

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)

Screw Terminal wire size

ECAI00-II

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

adjustment indicated in Section 6.1
