KRIPAL’s UKC1-P series (2-pole, 10A–40A) and UKC1-D series (3-pole, 20A–25A) are engineered specifically for the rigorous demands of HVAC switching. Built to handle high-inrush hermetic compressor motors and condenser fan loads, both series deliver robust, reliable performance for residential HVAC, heat pumps, and light commercial refrigeration systems. Our contactors ensure long-term durability and resistance to contact welding even under frequent cycling.
Technical Specifications of the UKC1-P & UKC1-D Series
Rated Current: 10A to 40A
Our contactors are fully capable of carrying Full Load Amperage (FLA) and withstanding transient Locked Rotor Amperage (LRA) during motor starting, ensuring stable operation during the high-stress startup phase.
Pole Configurations: 2P and 3P
2-pole configurations are optimized for single-phase residential air conditioning compressors.3-pole configurations are specifically designed for three-phase commercial HVAC and chiller systems.
Definite Purpose Construction
Engineered for the unique operating conditions of the HVAC industry, these contactors are built for high-frequency switching duty cycles. They are ideally suited for repetitive cycling controlled by thermostat signals and defrost control systems.
Control Coil Options
These contactors offer a comprehensive range of AC control voltages (24V–550V), ensuring seamless integration with HVAC thermostats, control boards, and building management systems (BMS). Designed to meet global electrical standards, they provide reliable, high-performance switching in any regional power environment.
Compact UKC1 Mounting Platform
Featuring a standardized physical footprint, our platform facilitates direct drop-in replacement within space-constrained condenser panels, air handler enclosures, and OEM electrical compartments.

Behind KRIPAL HVAC Contactor Manufacturing and Export
KRIPAL manufactures UKC1-P & UKC1-D definite purpose contactors on a dedicated HVAC production cell within our Zhejiang facility. These contactors are rigorously tested using hermetic compressor load simulation stations that replicate the Locked Rotor Amps (LRA) and high-frequency cycling conditions encountered in air conditioning equipment globally.
HVAC-Specific Production Cell
To ensure superior reliability, the UKC1-P & UKC1-D series are produced on a dedicated cell separate from general-purpose contactors. This line is specifically tooled to meet the stringent coil encapsulation standards and terminal torque specifications required by HVAC compressor loads.
Hermetic Compressor Load Simulation Testing
Every production batch undergoes cycle testing under LRA conditions on specialized benches. We validate the contactors’ resistance to contact welding under actual start-stop cycles, ensuring they surpass standard AC-3 switching requirements.
Seasonal Production Capacity Planning
Recognizing the seasonal nature of HVAC manufacturing, KRIPAL builds UKC1-P & UKC1-D inventory ahead of the spring ramp-up to ensure stable supply and prevent constraints during peak assembly periods.
UL and Regional Certification Support
The UKC1-P & UKC1-D series are designed for global compatibility and comply with relevant UL standards and regional HVAC codes. We provide proactive certification support to help your engineering team accelerate market approval.
OEM Inventory Buffer for Assembly Lines
KRIPAL maintains dedicated OEM safety stock for all contactor variants, synchronized with your production schedules. This strategic buffer safeguards your assembly lines against supply volatility and downtime.
Custom Branding and Part Number Marking
