Figure 9: TE Series Overload Trip Curves

Overload Protection During Bypass
When a Bypass Contactor is used to shunt power around the SCRs in the TE Series (as in the TE…-BP
version), overload protection is maintained as long as the TE Series is directly controlling the contactor.
No additional Overload Relay is necessary for normal operation.


Special Consideration for Across-the-Line (Direct-on-Line) Contactors
When the Bypass Contactor on a TE…-BP Series has been selected to be used for Across-the-Line
restart, supplemental overload protection must be added. For this application, refer to the External
Overload Relay Applications supplement and wiring diagram in Appendix 5 and section 4.2.6.a of the full
Installation, Operation and Maintenance Manual for detailed instructions.
