The KMC Controls CCE-3003 is a high-performance 3-stage pneumatic-electric relay designed for precise sequencing in commercial HVACR systems. Engineering to convert a single pneumatic air signal into three distinct electrical outputs, this PE switch is the primary replacement for the CCE-3013. It is commonly utilized for multi-stage electric heat control, fan induction terminal start-up, and refrigeration sequencing. Each stage features independent SPDT switching, providing versatile control over 120, 240, or 277 VAC circuits with a robust 25-amp non-inductive rating. Built for reliability in demanding environments, the KMC CCE-3003 offers a field-adjustable setpoint range of 2 to 20 psig and a tight fixed differential of 1 to 2 psi. This ensures accurate response times and prevents rapid cycling of equipment. Its non-position-sensitive design allows for flexible panel mounting or bulkhead installation without compromising calibration. As a veteran-grade HVAC pneumatic pressure switch, it is UL recognized and CSA certified, ensuring compliance with rigorous industrial safety standards for building automation systems. Key Benefits Direct CCE-3013 Replacement: Simplifies retrofits and maintenance by serving as the verified successor to the legacy CCE-3013 model. Heavy-Duty Electrical Capacity: Equipped with three 25A switches capable of handling 1 HP at 125 VAC and 2 HP at 250 VAC. Multi-Input Flexibility: Designed with dual inputs to accommodate complex sequencing of electric duct heaters or cooling stages. Superior HVAC Durability: Rated for operating temperatures between 40??F and 120??F, ideal for mechanical room environments. Common Questions How do I adjust the staging setpoints? Calibration is achieved by adjusting the internal setpoint screws to the desired psig levels within the 2-20 psi range to trigger each SPDT switch in sequence. Can this relay be used with non-KMC pneumatic systems? Yes, as a standard pneumatic-electric interface, it is compatible with any clean, dry 3-15 psi or 0-20 psi control air signal regardless of the controller manufacturer. What is the maximum pressure limit for the CCE-3003? While the operating setpoint range is 2 to 20 psig, the unit is rated for a maximum pressure of 30 psig to protect the internal diaphragms from surges.
