Frequently Asked Questions

What is the DAYTON Overload Relay used for?

The DAYTON Overload Relay provides thermal protection for three-phase motors by monitoring current and tripping on overload or phase loss. It is used in industrial motor control panels, conveyors, pumps, and HVAC equipment to prevent motor damage from excessive heat or unbalanced supply.

What are the specifications of the DAYTON Overload Relay ?

The DAYTON Overload Relay is an IEC thermal overload relay with 3 poles, 1NO/1NC auxiliary contacts, and phase loss sensitivity. It has an adjustable current range of 4 A to 6 A and includes integrated bimetallic elements, so no separate thermal units are required. It is compatible with Dayton contactors rated 9 to 18 Amps.
