The 111P is a single-phase pump monitor designed to protect pumps from dry-well, dead-head, jammed impeller, rapid-cycling, overvoltage, and undervoltage conditions. It operates on 115VAC with a load range of 1/3 to 1 hp, and features an onboard calibration process and adjustable sensitivity from 70% to 90% of the calibrated run power. The unit has a SPST output relay rated at 1 hp at 120VAC (16A max), with trip delays of 5 seconds for overcurrent and 4 seconds for dry-well, and restart delays of 2 seconds for over/undervoltage faults. Dimensions are 73.66 mm H x 133.35 mm W x 73.99 mm D, with wire terminals accepting 10-22 AWG and mounting via #8 screws. It is cULus listed to UL508 and C22.2 No. 14 standards. An infrared interface supports connection to the separate Informer diagnostic tool.
The 111P is a single-phase pump monitor with an input voltage value of 115 V ac and an input load range of ⅓–1 hp. The dimensions of this unit are 2.93” H x 5.25” W x 2.91” D.
