High Performance Circuit Breakers (HPCBs)

Versatile, reliable and high-performing

In the demanding world of critical power and data centers, our compact S800 series of high-performance circuit breakers reliably protects against short circuits and overloads. Engineered with advanced technology to limit let-through energy and high peak currents, it covers multiple configurations for applications ranging from hospitals and telecommunications to renewable energy systems like photovoltaics and wind turbines.

Compliant with stringent IEC and UL standards, the S800 ensures safety and robustness in various environments, including railway, where it meets rigorous fire and smoke, shock and vibration standards. With features like fast remote-controlled operation and self-resetting short-circuit limiters, the S800 series provides effective group protection and reliability for all your electrical protection needs.
