Chapter 2 Installation & Wiring
• The earth ground terminal of the E3 Overload Relay shall be connected to
a solid earth ground via a low-impedance connection.
• Installations employing an external ground fault sensor shall ground the
cable shield at the sensor with no connection made at the E3 Plus Overload
Relay.
• The PTC thermistor cable shield shall be grounded at the E3 Plus
Overload Relay with no connection made at the opposite end.
Short-Circuit Ratings
The E3 Overload Relay is suitable for use on circuits capable of delivering not
more than the RMS symmetrical amperes listed in the following tables.
