The SPP-235P Single-phase Submersible Pump Protector is a pump monitor designed to protect
single-phase pumps from dry-well, dead-head, rapid-cycle, jammed impeller, and over/under
voltage conditions. The Submersible Pump Protector SPP-235P protects 5 to 15 HP, 230VAC
pumps. Typical applications include submersible pumps, centrifugal pumps, cooling pumps,
environmental pumps, residential water wells, commercial water wells, irrigation wells, and golf
course or other sprinkler equipment.
CONNECTIONS
NOTE: Use with UL/CSA listed overload or impedance protected pumps or motors only.
1.
Mount the Submersible Pump Protector Model SPP-235P in a convenient location in or near
the pump control box. If the location is wet or dusty, a NEMA 3R, 4, or 12 enclosure should be
used. The Submersible Pump Protector must be protected by a fuse or circuit breaker.
2.
Connect a current transformer (CT) to the SPP’s terminals marked CT1 and CT2. (see Table
for proper CT sizing).

NOTE: One line from the fused disconnect must pass through the current transformer.
NOTE: The Submersible Pump Protector will not function without an external current
transformer. A UL Listed current transformer must be selected based on Table 1.
NOTE: The Submersible Pump Protector may not detect a dead-head (blocked pipe)
condition on applications where the pump is undersized for a given motor or flow restrictors
re used on high stage pumps or low yield wells.
