Applicable Motors
The G3JA-D can be used for a 3-
phase, 6-wire motor that supports
star-delta starting. It is compact
and equipped with star-delta
starting capabilities, as shown at
the right.

Note:
The soft start and current
limit start functions cannot
be used at the same time.
Applicable Motors
The G3JA-C is connected as shown
in the diagram at the right. It can
thus be used with a 3-phase, 3-lead
motor. (When using a 3-phase, 6-
lead/12-lead motor, delta wiring is
required in the motor.

Built-in Bypass Relay and Smooth Motor
Starts Achieved in a Compact Starter
• A current limit start for a 3-phase, 6-lead motor achieves the
functionality of a star-delta starter with internal wiring.
• Phase control using a thyristor limits current when the motor
starts, and a bypass relay minimizes power loss while the motor
is running.
• Built-in electronic thermal overload relay.
• Built-in fault diagnosis for thyristor overtemperature, phase loss/
open load, current imbalance, and thyristor short-circuits.
• cULus listed; complies with IEC standards.
• Mounts with screws or to DIN track.
• Built-in operation/fault indicator.
• Built-in auxiliary contact for fault indication.
• An optional Auxiliary Contact Block can be mounted to output
operating status.
