Copeland 943-0120-00 SecureStart Module Kit

The Copeland 943-0120-00 SecureStart Module Kit is a field-proven soft start controller designed specifically for single-phase compressors in residential and commercial HVAC units. As an authentic OEM module kit, it addresses common startup issues such as light flickering and high in-rush current, effectively reducing peak starting amps by up to 75%. This kit is engineered for 200/230 VAC applications at 50/60 Hz and comes complete with a start capacitor, start relay, and a dedicated wiring harness. Its robust ABS plastic body provides environmental protection, while the integrated low voltage protection and emergency shutdown delay function prevent motor stalling and catastrophic failure during power fluctuations. Compatible with ZR, ZP, and ZPS series compressors and optimized for R-410A, R-22, and R-407C refrigerants, this module is the industry standard for enhancing single-phase compressor protection and improving power quality at the point of use.

• Reduces In-Rush Current: Lowers the initial amperage spike during startup, preventing circuit breaker trips and reducing mechanical stress on internal compressor components.
• Voltage Monitoring: Built-in low voltage protection automatically disconnects the motor if the power supply becomes unstable, preventing insulation damage and overheating.
• Universal Compatibility: Engineered for 1.5 to 5-ton single-phase compressors across multiple Copeland Scroll model lines.
• Enhanced Power Quality: Minimizes the voltage drop within the building's electrical system, eliminating the nuisance of dimming lights when the A/C cycles on.
• Durable Construction: The ABS plastic body and high-quality internal electronics are designed for the high-duty cycles of HVACR operation.

What is the primary function of the SecureStart module?
It functions as a soft start kit that manages the initial power surge required to move the compressor from a standstill, protecting the motor windings and local electrical grid.

Does this kit replace a standard potential relay and capacitor?
Yes, it replaces traditional start components with a more advanced electronic control system that optimizes starting torque and provides in-rush current reduction.

Can this be installed on any single-phase unit?
While designed for Copeland 943-0120-00 applications, it is generally compatible with ZR, ZP, and ZPS series single-phase scroll compressors utilizing R-410A and other common refrigerants.
