Pentair smc-cr1521-02 Submersible Motor Control Box 1.5 Hp

Product Description

The PENTAIR smc-cr1521-02 is a submersible motor control box designed for single-phase well pump motors requiring Capacitor Start / Capacitor Run (CSCR) operation. Rated at 1.5 HP and 230 volts, this control box manages motor starting and running capacitor functions to deliver reliable pump starts under load. It is installed above ground, typically in a utility area near the pressure tank, and is serviced by licensed well pump contractors or electricians familiar with submersible pump systems. CSCR configurations are commonly used where sustained torque and consistent motor performance are required in demanding or high-temperature environments.

This control box fits residential and light commercial well pump installations where a 1.5 HP single-phase submersible motor is in service at 230 volts. Pentek offers a full range of models from 1/2 HP through 5 HP, and this unit is designed to be interchangeable with existing motor controls for both CSIR and CSCR applications. It is suited for harsh conditions and elevated ambient temperature installations where standard controls may underperform.
