777-LR-KW-HP-P2 - SymCom 3-Phase Power Monitor 200-480V 1-800 FLA Plus
The Model 777-KW/HP-P2 Series Family
The Model 777-KW/HP-P2 Series has the underload trip, adjustable on the face of the unit, based on power, while all the other products in the 777 family provide an undercurrent trip.
The underpower trip feature is desirable anytime the current vs. load characteristic is non-linear or has little change. In general terms, smaller motors and slow speed motors have little change in current over the normal load range. Larger motors that are running light loads will also show small current changes over the operating load range.
KW/HP products should be used with all small centrifugal motors and fractional horsepower motors when underload protection is needed and with most motors under 3hp. 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.
The 777-KW/HP-P2 can display kilowatts and horsepower and a high power trip feature that can be enabled over a network. The high power trip is useful added protection for positive displacement pumps in a restricted flow (dead-head) condition.
- LR (Low Range) The 777-LR-KW/HP-P2 is specifically designed for use with 1-9 FLA motors to ease installation when wired directly, or for 10-800 FLA motors with use of external CTs.
- HVR The 777-HVR-KW/HP-P2 is required when a CPT (control power transformer) is not used on a 480V system. It has a 340-480VAC range, a relay rated at 470VA @ 600VAC pilot duty, and is commonly used in pumping applications to save the cost and extra wiring associated with a CPT.
- 575 The 777-575-KW/HP-P2 has a nominal 500-600VAC range and 240V relay. They are commonly used in Canada and the Northeast US where 575V utility power services are common.
- MLR The 777-MLR-KW/HP-P2 is used in applications that have a 0.5-21 and 40-740 full load amp range. It is wired directly without the need to loop conductors for 5-21 amps (under 5 amps requires looping of conductors), and can be used with external CTs for 40-740 amps.
