Product Description

The EATON Overload Relay is a NEMA Size 0 electronic protection device with three poles, rated for 1 A to 5 A and a maximum voltage of 690V AC. It features screw clamp terminals and is compatible with the C25 Definite Purpose contactor series. This three-phase relay does not require thermal units, as it is an electronic type.

Frequently Asked Questions

What is the EATON C440 overload relay used for?

The EATON C440 electronic overload relay protects three-phase motors from overload and phase loss in industrial applications. It is designed for NEMA Size 0 starters and pairs with the C25 Definite Purpose contactor series, making it suitable for pumps, fans, and conveyors.

What are the specifications of the EATON C440A1A005SF0 overload relay?

The EATON C440A1A005SF0 is a three-pole electronic overload relay rated for 1 A to 5 A with a maximum voltage of 690V AC. It uses screw clamp terminals, requires no thermal units, and is compatible with the C25 Definite Purpose contactor series. It is a NEMA Size 0 device.

Where to buy the EATON C440 overload relay worldwide?

You can source the EATON C440 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 on this EATON part.

How to select the correct EATON overload relay for a motor?

Select the EATON overload relay by matching its current range to the motor full-load amps. For the C440A1A005SF0, set the dial between 1 A and 5 A. Ensure the relay is compatible with your contactor series—this model works with C25 Definite Purpose contactors. No thermal units are needed for electronic types.
