Frequently Asked Questions

What is the EATON C440A1A020SAX overload relay used for?

The EATON C440A1A020SAX is a three-phase NEMA electronic overload relay used to protect motors from overcurrent, phase loss, and other electrical faults. It is commonly applied in industrial motor control centers and panel builds where reliable, adjustable protection is required without thermal units.

What are the specifications of the EATON C440A1A020SAX overload relay?

The EATON C440A1A020SAX is a three-phase electronic overload relay rated for 4 A to 20 A with a maximum voltage of 690V AC. It uses screw clamp terminals and is compatible with the Freedom contactor series. Thermal units are not required for this electronic type.
