Installation and Wiring
Control Circuits
The E300 Electronic Overload Relay can provide motor control logic for many
different types of motor starters (see
for more information on
Operating Modes). By default, the E300 is configured for the Overload-Network
operating mode. The following wiring diagrams are typical control circuits for
Non-Reversing and Reversing Motor starters that use the Overload-Network
operating mode when Relay 0 (terminals R03 and R04) is configured to be a
normally closed Trip Relay.

ATTENTION:
Do not exceed the ratings of the E300 Electronic Overload Relay’s
output and trip relay. If the coil current or voltage of the contactor exceeds the
overload relay’s ratings, an interposing relay must be used.
ATTENTION:
When the power is applied to the E300 Electronic Overload Relay’s
A1 and A2 terminals, the N.O. relay contact that is assigned as a Trip Relay closes
after approximately 2 seconds if no trip condition exists.
ATTENTION:
More control circuit protection may be required. See the
applicable electrical codes.
