CF/CS 30 ATEX Series High-Performance Electromechanical Power Relays

The CF30 and CS30 ATEX series from Carlo Gavazzi represent a robust and reliable solution for demanding industrial applications, especially those involving hazardous environments with explosive atmospheres or flammable refrigerants. Designed to meet stringent international standards, including ATEX (TÜV), UL508, and NWFR UL, these electromechanical power relays are ideal for use in HVACR systems, oil and gas operations, and compressor control systems.

Available in two terminal configurations—CF Fast-on and CS (PCB) soldering—the relays support both AC and DC coil voltages ranging from 6 V_DC to 277 V_AC. They offer two contact configurations: two normally open (DPST) or two changeover (DPDT) contacts, each rated for 30 A switching capacity. The series features reinforced insulation (4 kV/8 mm), IP67 sealed enclosures, and high mechanical and electrical endurance, ensuring long-term reliability even under extreme conditions.

With a wide operating temperature range (-40°C to +85°C), high surge voltage protection (10 kV), and compatibility with low-GWP refrigerants, the CF 30 and CS 30 ATEX series empower OEMs to meet evolving safety and environmental standards. These relays are a strategic choice for engineers seeking performance, compliance, and versatility in one compact package.
