Product Description
PENTEK SPP-111P 1/3–1/2HP 115V Single-Phase Protector
NEMA 3R
115VAC
1/3 - 1/2 HP
Applications
Water systems…for residential, multiple housing, farm and
commercial installations, where a 4" submersible 3-wire motor
is used.
SPP-111P & SPP-231P Insiders are “current monitors” designed
to protect Single-Phase pumps, which fit inside 1/3 - 1 HP 115V and
230V CSIR control boxes. A simple adjustment allows the Insider to
be calibrated to your specific pumping applications, reducing the
possibility of false or nuisance tripping. Its unique microprocessor
constantly monitors the incoming power for fluctuations in voltage
and current. If loss of suction or other abnormality is detected, the
Insider deactivates its output relay and directly disconnects the
pump motor. Then it begins its user-selectable “Restart Delay/
Dry Well Recovery” timer. When the timer counts zero or power is
removed and reapplied, the Insider reactivates its output relay and
turns the pump back on
Protects pumps from
Dry Well Overvoltage Flow Restriction (Dead Head)
Undervoltage Overcurrent (Jammed Impeller)
