What is contactor current in electromechanical relays?

(1/5) > >>

I was going through DPDT configured electromechanical relay specifications and came across contactor current per pole. The contactor current for that DPDT relay was mentioned as 1A per pole. So, exactly what is that contactor current per pole, and how does it differ from the usual current rating of relays?

1A seems to be in a strange range for a contactor. It's too much for the coil itself, and a very low value for the current handling capacity of a contactor.

Can you post a datasheet, or at least a direct link to the info you found?

It's probably a normally 1A relay but the manufacturer simply used the word contactor by accident or because their English wasn't that good.

Some contactors have auxiliary contacts, for switching low power levels.

Terry Bites:
The small current needed to pull in and latch the relay is far less than the main contactor contacts. It has to provide the coil with enough power to overcome the return spring. The latch / safety loop contacts are low current. A 100A contactor may only need an amp or less to actuate. 250-500mA is typical.

The difference between contactors and relays is that a relay may have no, nc or co contacts and a contactor always has no main contacts. If its DPDT its not likely to be a contactor.
