Frequently asked questions
Common questions about Overload Relay from 3G Electric.
How do I size an overload relay for my motor?
Match the relay's current range to the motor's full-load amperage (FLA) from the nameplate. Set the dial to FLA or slightly below for service factor 1.0 motors. For adjustable electronic relays, use the motor's FLA and select a trip class suited to your starting duty.
What is the difference between NEMA and IEC overload relays?
NEMA relays are physically larger, offer greater current adjustment ranges, and are common in North American panels. IEC relays are compact, modular, and widely used globally. Choose based on your panel design, motor size, and regional standards.
Which brands of overload relays does 3G Electric stock?
We supply overload relays from Schneider, Siemens, Eaton, Square D, Dayton, and GE. This range covers both thermal and electronic types in NEMA and IEC configurations, giving you flexibility for new installations or replacements.
