Thermal Overload Tripping
Thermal Overload Tripping
(OP)
I have 6 thermal overload relays that frequently trip. They each serve a blower with a 3 Phase 460 V 15 horsepower motor. We measured the voltage at the relays and it registered 510 Volts. Could this be causing the trips?

Measuring the current is also an excellent idea.
