Diversi-Tech TTMJ340 Motor Start Capacitor 340-408 MFD 110/125V Round

The Diversi-Tech TTMJ340 is a 340–408 MFD motor start capacitor rated for 110/125 VAC operation. Designed for intermittent duty in single-phase AC motor starting circuits, it delivers the high-current surge needed to reliably start motors in HVAC systems, refrigeration units, air compressors, pumps, and other single-phase motor applications.

Key Features:

• Capacitance: 340–408 MFD (±5% tolerance)
• Voltage Rating: 110/125 VAC, 50/60 Hz
• Dry, electrolytic, non-polarized construction for intermittent AC motor starting duty
• Round case constructed of moisture- and oil-resistant molded phenolic resin or plastic
• Standard dual blade terminals for quick, secure installation
• Rated for 3-second starts at up to 20 starts per hour
• Operating temperature range: -40°C to +65°C (-40°F to +149°F)
• UL recognized and cUL approved
• Meets or exceeds Electronic Industries Association (EIA) Standard RS-463 Type 2

This start capacitor provides the initial torque boost required to bring single-phase motors up to operating speed, then drops out of the circuit — helping extend motor life and improve starting efficiency. Its compact round profile and dual blade terminals make it a straightforward drop-in replacement for worn or failed OEM start capacitors across a wide range of HVAC and refrigeration equipment.
