HVAC Contactors for Compressor & Fan Motor Control
KRIPAL manufactures definite purpose HVAC contactors specifically engineered for compressor, fan and pump motor switching in residential split systems, commercial rooftop units and heat pump applications. The UKC1-P series (10A to 40A, 2-pole and 3-pole) handles hermetic compressor locked-rotor currents and frequent cycling duty without contact welding. Universal mounting plate and 24V, 120V, 208/240V coil options match standard HVAC control transformer outputs, simplifying replacement and new equipment integration.

KRIPAL’s UKC1-P series is engineered specifically for the rigorous demands of HVAC switching. Built to handle high-inrush hermetic compressor motors and condenser fan loads, this series delivers robust, reliable performance for both residential HVAC and light commercial refrigeration systems.
Technical Specifications of the UKC1-P Series
Rated Current: 10A to 40A
Fully capable of carrying Full Load Amperage (FLA) and withstanding transient Locked Rotor Amperage (LRA) during motor starting.
Pole Configurations: 2P and 3P
2-pole configurations are intended for single-phase residential air conditioning compressors, while 3-pole configurations are intended for three-phase commercial HVAC and chiller systems.
Definite Purpose Construction
Designed for HVAC operating conditions with high-frequency switching duty cycles. Suitable for repetitive cycling controlled by thermostat signals and defrost control systems.
Control Coil Options
Available in 24V, 110-120V, and 220-240V AC control voltages, suitable for use with HVAC thermostat control relays, electronic control boards, and building management systems (BMS).
Compact UKC1 Mounting Platform
Features a standardized physical footprint. Facilitates direct drop-in replacement within space-constrained condenser panels, air handler enclosures, and OEM electrical compartments.
HVAC Equipment Built Around UKC1-P Contactors
KRIPAL UKC1-P definite purpose contactors are engineered for residential and commercial HVAC equipment, providing reliable compressor and fan motor switching in heating and cooling systems that require frequent daily cycling across seasonal temperature variations.
Residential Split System Air Conditioners
UKC1-P 2-pole contactors are intended for switching hermetic scroll compressor motor loads in residential ducted and ductless split systems. Engineered for high electrical and mechanical endurance in residential HVAC duty, with ratings matched to compressor locked rotor current (LRA) during motor starting.
Commercial Rooftop Packaged Units
Three-phase UKC1-P models power packaged rooftop HVAC systems across retail, commercial office, and hospitality sectors. Engineered for continuous-duty performance throughout peak cooling seasons, they ensure exceptional electrical and thermal endurance even under the most demanding repetitive switching conditions.
Heat Pump and Walk-In Cooler Condensing Units
The UKC1-P series integrates seamlessly into heat pump HVAC systems with reversing valve control circuits, and drives outdoor condensing units for supermarket walk-in coolers and refrigerated display cases in demanding food retail environments.

Behind KRIPAL HVAC Contactor Manufacturing and Export
KRIPAL manufactures UKC1-P definite purpose contactors on a dedicated HVAC production cell within our Zhejiang facility, with hermetic compressor load simulation test stations that replicate the locked-rotor and cycling conditions these contactors face inside air conditioning equipment worldwide.
HVAC-Specific Production Cell
UKC1-P contactors do not share a production line with general-purpose industrial contactors. The dedicated cell is tooled for the higher coil encapsulation standards and terminal torque specifications that HVAC compressor loads demand.
Hermetic Compressor Load Simulation Testing
Every production batch undergoes rigorous cycle testing under Locked Rotor Amps (LRA) conditions on specialized compressor load simulation benches. We validate our contactors’ resistance to contact welding under actual HVAC compressor start-stop cycles, surpassing standard general-purpose AC-3 switching requirements.
Seasonal Production Capacity Planning
HVAC manufacturing follows a seasonal demand cycle. KRIPAL builds UKC1-P inventory ahead of the spring production ramp-up to ensure stable supply and prevent production constraints during peak HVAC assembly periods.
UL and Regional Certification Support
Designed for global compatibility, the UKC1-P series complies fully with UL 508 / UL 60947-4-1 and regional HVAC codes. We provide proactive certification support, ensuring your engineering team can accelerate market approval and focus on product innovation.
OEM Inventory Buffer for Assembly Lines
KRIPAL offers dedicated OEM safety stock for all UKC1-P variants, synchronized perfectly with your weekly production schedules. This strategic buffer eliminates supply volatility, safeguarding your HVAC assembly lines against costly downtime during peak manufacturing cycles.
Custom Branding and Part Number Marking
We provide full OEM branding via precision laser-marking. Each contactor features your logo, internal part numbers, and LRA ratings, while keeping KRIPAL’s identity completely neutral. This ensures your brand remains the sole focus, reinforcing your corporate integrity during field service and maintenance.
Single-Source HVAC Component Bundling
Streamline your procurement by consolidating UKC1-P contactors, run capacitors, and potential relays into a single order. This unified sourcing strategy simplifies your supply chain and reduces logistics costs through consolidated shipments.
Direct Engineering Access for HVAC OEMs
Work directly with KRIPAL’s HVAC engineering team to finalize your LRA specifications, coil voltages, and terminal configurations. By cutting out middleman delays, we ensure your design requirements are communicated clearly and implemented immediately.
