KMC Controls CCE-3001 Control

The KMC Controls CCE-3001 is a professional-grade, single-stage pneumatic-electric relay designed for seamless integration into building automation and HVAC control schemes. This industrial-duty SPDT (Single Pole Double Throw) pressure switch is engineered to actuate electrical circuits based on a specific pneumatic signal, making it a standard component for managing fan induction terminals, refrigeration stages, or electric heating sequences. Operating effectively at 277V, the unit features a robust polycarbonate housing and a silicone diaphragm, ensuring long-term reliability in demanding mechanical environments.

This HVAC pneumatic relay offers a field-adjustable setpoint range of 2 to 20 psig with a fixed differential of 2 psi, providing precise switching action without the risk of frequent hunting. The non-position-sensitive design allows for versatile installation on flat surfaces or within bulkheads, facilitating easy replacement for veteran technicians. With a maximum operating pressure of 30 psi and electrical ratings up to 25 amps non-inductive, the CCE-3001 delivers the switching capacity required for heavy-duty PE switch applications.

• High-Capacity Switching: Rated for 25A at 277VAC (non-inductive) to handle significant electrical loads or motor starts.
• Versatile Mounting: Non-position-sensitive construction ensures reliable operation regardless of orientation.
• Durable Components: Features a high-quality silicone diaphragm and polycarbonate body for consistent performance.
• Precise Control: Fixed 2# differential maintains stable circuit status across the 2-20# adjustable pressure range.
• Code Compliant: UL recognized and CSA certified for industrial and commercial HVACR installations.

• Can this relay be used for both heating and cooling? Yes, the SPDT configuration allows for both normally open and normally closed operations, depending on your wiring scheme.
• What size pneumatic tubing is required? The unit is designed for standard 1/4 inch O.D. polyethylene tubing via 3/16 inch nipples.
• Is the differential adjustable? No, the CCE-3001 features a fixed differential (typically 1 to 2 psi) to prevent short-cycling of equipment.
