The 777-KW/HP products should be used with all fractional horsepower motors when underload protection is needed, and with most motors under 3 hp. Also use KW/HP products when the motor is derated (Ex: Coal bed methane well with a 7.5hp submersible pump on a 10hp motor.) Other typical applications are mixer motors up to 50hp and beyond that run at less than 1800 rpm, magdrive pumps and can pumps. If in doubt, underpower can be used anytime in place of undercurrent protection. Settings can be either horsepower or kilowatts. |
