The relay covers a current range of 2.5 A to 4 A and requires no external thermal units.

Frequently Asked Questions

What is the DAYTON Overload Relay used for?

The DAYTON Overload Relay provides thermal protection for three-phase motors by using integrated bimetallic elements to prevent overheating. It is commonly applied in industrial motor control panels and conveyor systems where reliable overload and phase-loss protection is required.

What are the specifications of the DAYTON Overload Relay ?

The DAYTON Overload Relay is a 3-pole IEC thermal overload relay with a current range of 2.5 A to 4 A. It includes 1NO/1NC auxiliary contacts, phase loss sensitivity, and integrated bimetallic elements, so no external thermal units are needed. It is compatible with Dayton contactors rated 9 to 18 Amps.

Where to buy the DAYTON Overload Relay worldwide?

You can source the DAYTON Overload Relay through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine DAYTON components for motor protection applications.

How to select the correct DAYTON Overload Relay for a motor?

Select the DAYTON Overload Relay by matching its current range to the motor full-load amperage. For the model, the setting range is 2.5 A to 4 A. Ensure the relay is paired with a compatible Dayton contactor (9 to 18 Amp models) and that the auxiliary contact configuration (1NO/1NC) meets your control circuit needs.
