Carlo Gavazzi Expands Power Component Portfolio with ATEX-Certified CF/CS 30 Series Relays
The engineering focus of the CF/CS 30 ATEX Series centers on material resilience and electrical endurance. The housing utilizes specialized polymers that satisfy the GWT 750°C (Glow Wire Test) standard, a crucial metric for preventing fire propagation caused by overheated internal components or electrical arcing. Capable of switching up to 30A at 600VAC, the series offers significant power density in a compact footprint. Engineers can choose between the CF Fast-on terminal version for traditional panel wiring or the CS Soldering (PCB) variant for integrated circuit board mounting. With a 10kV surge voltage resistance between coil and contacts, the relays provide a robust barrier against transient spikes, ensuring the long-term stability of sensitive control logic in heavy-duty industrial environments.
Versatility remains a cornerstone of the series, supporting a wide spectrum of AC and DC coil voltages ranging from 6VDC up to 277VAC. The contact configurations—available as DPDT (2 Changeover) or DPST (2 Normally Open)—allow for flexible integration into pump and compressor control systems where secondary safety interlocks are often required. Furthermore, the wide operating temperature range of -40°C to +85°C ensures reliable switching performance even in extreme outdoor or high-heat processing conditions. By adhering to UL508 standards, Carlo Gavazzi provides a globally recognized platform for OEMs looking to standardize their disaster recovery and power management hardware across international markets.
