SEL-701 Motor Relay Application
The SEL-701 Motor Relay provides comprehensive motor protection, includ-
ing short circuit, load loss, load jam, and frequent starting protection as well as
unbalance current and phase reversal protection. The patented motor thermal pro-
tection element used by the SEL-701 Motor Relay accurately tracks the heating
effects of overloads and unbalance current.
Combining the SEL-2600 and the SEL-701 Motor Relay enhances this list of
protection features by adding remote RTD-based thermal protection.
