E300 Electronic Overload Relay
For the E300 Electronic Overload Relay to function properly and protect your motor, it needs a control voltage (24V DC, 120V AC,
240VAC).Connect the control voltage to the device by attaching wires to the A1 (positive) and A2 (negative) terminals, which are located on the
bottom of the control module of the E300 relay. Figure 4 shows this configuration.
Figure 4 - Control Module Wiring
The E300 relay typically is wired in one of two different motor connections: a three-phase, direct-on-line (DOL), and a single-phase, full-voltage
connection. Figure 5 shows these connections.
