The KMC Controls CCE-3002 is a professional-grade 2-stage pneumatic-electric switch (P/E relay) engineered for precision control in commercial HVACR systems. As a veteran-preferred pneumatic-to-electric relay, this unit is the direct replacement for the legacy KMC CCE-3012, offering seamless integration into existing control loops without the need for extensive recalibration. The CCE-3002 features dual SPDT switching stages, allowing contractors to manage complex sequences such as multi-stage electric heating, refrigeration banks, or fan induction terminal starts from a single pneumatic air signal. Designed for reliability in demanding environments, this HVAC pressure switch supports an electrical rating of up to 25 amps at 277 VAC, making it suitable for heavy-duty pilot duty and motor loads up to 2 HP. The device operates with a setpoint range of 2 to 20 psig and utilizes a fixed nominal differential of 1 to 2 psi to prevent short-cycling. Its non-position-sensitive design allows for flexible panel mount or bulkhead installation. For optimal performance, ensure the pneumatic control air is clean and dry to prevent premature component failure. Key Benefits: Dual Stage SPDT Switching: Provides independent control for two distinct electrical circuits from a single pneumatic input. Direct Retrofit Compatibility: Serves as the official CCE-3012 replacement, maintaining technical specifications and mounting footprints. High Electrical Capacity: Rated for 25A non-inductive loads, handling large electric heating stages and fan motors with ease. Rugged Temperature Range: Reliable operation in ambient conditions ranging from 40??F to 150??F. UL and CSA Recognized: Meets stringent industry safety standards for industrial and commercial control relay applications. Common Questions: What is the maximum pressure rating for the CCE-3002? The unit is rated for a maximum pressure of 30 psig. Operating beyond this threshold may damage the internal bellows. Can I mount this switch in any orientation? Yes, the KMC CCE-3002 is not position-sensitive and can be mounted on vertical or horizontal surfaces. Does this replace the single-stage CCE-3001? While it can technically perform the same function, the CCE-3002 is specifically a 2-stage unit. If you only require one stage, the CCE-3001 is the standard choice.
