Armstrong Pumps 180200-172 Run Capacitor 15 Mfd 400/450 Vac

Product Description

The ARMSTRONG PUMPS 180200-172 is a motor run capacitor rated at 15 microfarads (MFD) and 400/450 volts AC. Run capacitors maintain a continuous phase shift in single-phase AC motors, keeping them running efficiently after startup. This capacitor measures 1.42 inches in diameter and 2.75 inches in height, making it a compact component suited for replacement in tight motor housings. It is installed by licensed HVAC technicians, pump service professionals, and electricians working on motor-driven equipment across residential and light commercial applications.

This capacitor is commonly used in motor run circuits for fans, pumps, and power supply applications. The dual voltage rating of 400/450 VAC provides flexibility across a range of motor specifications. The RPC2N156-M1 capacitor cross-references to Armstrong Pumps part number 180200-172, making it a direct service replacement for Armstrong-branded pump and motor assemblies in the field.

Key Features

Compatibility

Identified as Armstrong Pumps replacement part 180200-172, cross-referencing OEM part number RPC2N156-M1. Suitable for motor run applications in fan, pump, and power supply circuits requiring 15 MFD at 400/450 VAC.

Installation Notes

Run capacitor replacement should be performed by a qualified electrician or licensed HVAC or pump service technician. Disconnect and lock out all power to the motor before handling any capacitor, and discharge the capacitor fully before removal, as run capacitors can retain a lethal charge even after power is removed. Verify that the replacement capacitor matches the MFD rating and voltage rating of the original unit before installation. Work should comply with applicable NEC requirements and local electrical codes.
