Chapter 2 Installation and Wiring
Control Circuits
The E300 Electronic Overload relay is capable of providing motor control logic
for many different type of motor starters (refer to Chapter 4 for more
information on Operating Modes). By default, the E300 is configured for the
Overload-Network operating mode in which Relay 0 (terminals R03 and R04) is
configured to be a normally closed Trip Relay. The following wiring diagrams are
typical control circuits for Non-Reversing and Reversing Motor starters that use
the Overload-Network operating mode.

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 assigned as a Trip Relay will close
after approximately 2 seconds if no trip condition exists.
ATTENTION: Additional control circuit protection may be required. Refer to the
applicable electrical codes.
