Submersible Pumps – Optimized Protection

Littelfuse.com/Pump-Protection

Description

The Littelfuse 235P is designed to protect 5-15hp, 230V,

single-phase pumps from dry-well, dead-head, rapid-cycle,

jammed impeller, and overvoltage and undervoltage conditions.
A calibration adjustment allows the 235P to be calibrated

to your specific pumping applications, thereby reducing the

possibility of false or nuisance tripping. A unique microcontroller-

based voltage and current-sensing circuit constantly monitors

the incoming power for fluctuations causing overcurrent and

undercurrent. When an abnormality, such as loss of suction

is detected, the 235P deactivates its output relay and directly

disconnects the pump motor. The unit then begins its user-

selectable restart delay (dry-well recovery) timer. When the

timer counts to zero or power is removed and reapplied, the unit

reactivates its output relay and turns the pump back on.
The 235P communicates with a hand-held diagnostics tool

called the Informer (sold separately). The Informer displays

parameters including calibration points, trip points, run time and

last faults.
An external current transformer is required for operation

(sold separately).

Special considerations for pump cables larger than #10 AWG:

In some cases where larger motors are installed with deep

set pumps, pump cables are used that exceed the relay’s

terminal size. In these conditions, a short splice of #10 AWG or

#12 AWG may be a solution at the control box.

Note:

All local,

state and national electric codes should be followed when

applying this solution.

NOTE: The 235P model has a sensitivity adjustment for the dry-well trip point. After calibration
is done, you can adjust the sensitivity for the dry-well/dead-head trip point from 70-90% of the
full load. This makes the unit even more adaptable to varying pumping applications. If you have
a very low producing well, you increase the sensitivity closer to the 90% mark, or if you have a
very heavy producing well, you would decrease the sensitivity around the 70% mark.
