Secop Diversitech 117U5043 Start Capacitor

The Secop Diversitech 117U5043 Start Capacitor is a mission-critical component designed specifically for SC model compressors in commercial refrigeration and HVAC systems. As a veteran-grade refrigeration start capacitor, this unit provides the necessary phase shift to initiate compressor motor startup under high-torque conditions. Rated at 410 microfarads (MFD) and 125V, it ensures reliable activation of the start windings, reducing the duration of locked-rotor amperage (LRA) and protecting your compressor from overheating. Featuring a round start capacitor profile with an integrated mounting bracket and standard 1/4-inch terminals, it streamlines the replacement process in tight compact condensing units. This OEM Secop 117U5043 part is engineered to match the electrical specifications of Secop and Danfoss reciprocating compressors, facilitating rapid pressure equalization and high-efficiency restarts in low-voltage scenarios. Whether you are servicing reach-ins or walk-in coolers, this high-capacitance component is optimized for 50/60 Hz single-phase AC applications where motor winding protection and consistent torque are non-negotiable.

• Specifically engineered for Danfoss and Secop SC series hermetic reciprocating compressors.
• High 410 MFD capacitance provides the necessary current boost for rapid torque delivery during the start cycle.
• Durable cylindrical housing with integrated mounting bracket ensures secure installation in high-vibration environments.
• Standardized 1/4 inch quick-connect terminals allow for immediate drop-in replacement by field technicians.
• Approved to CQC standards, ensuring compatibility with rigorous commercial refrigeration duty cycles.

Is the Secop 117U5043 compatible with NF model compressors?
While both series may share similar physical footprints, the 117U5043 is specifically calibrated for SC model compressors. Always verify the MFD and voltage requirements on the specific compressor nameplate before installation.

Can I use a 115V rated capacitor in place of this 125V unit?
No. You may use a capacitor with a higher voltage rating, but never lower. This 125V unit is the industry standard for 110-120V primary voltage systems to handle start-up surges.

Why is my compressor humming but failing to start even with a new capacitor?
If a new 410 uF start capacitor does not resolve the issue, check the potential relay or PTC starter. A failed relay can prevent the capacitor from being dropped out of the circuit or prevent it from engaging entirely.
