Submersible Pumps – Optimized Protection
Single-Phase Pump Monitor in NEMA Box
Littelfuse.com/Pump-Protection
Enclosure with 233P mounted
Description
The ENCL enclosure is a metal electrical box that meets the
National Electrical Manufacturers Association’s and Underwriter
Laboratory’s standard for a 3R rating. The ENCL box can
house one of several single-phase Littelfuse Pump Protection
products. It has three clear lenses on the cover for viewing the
LEDs on the units, allowing the customer to determine the units
operational status and to provide access to the IR signal for use
with the Informer diagnostic tool.
The ENCL enclosure is sold ONLY in conjunction with the single-
phase 111P, 233P, 233P-1.5, and 235P models.
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 unit’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.
An external current transformer is required for operation of the
Model 235P (sold separately).
