ATS48 Which units would require the use of a pilot relay with the shorting contactor?<br /><br />
The internal relay is rated for 1.8A for 230VAC. Therefore it is good for 414 VA. Need to make sure the coil of the contactor is not greater than 414VA. The coil rating of the recommended contactors for units ATS48C25Y through ATS48M12Y exceed this rating therefore the pilot relay would be needed.
