The high-performance circuit breakers in the S800U series protect cables and lines against overload and short circuits. They have a rated short-circuit breaking capacity of 50kA at 240/415V AC. In addition, it can be used for voltages up to 240V AC according to UL489 with a breaking capacity of 50kA. With its thermal tripping mechanism, it offers equally effective protection against overload, as does its electromechanical tripping mechanism against short circuits. The S800U complies with the IEC/EN 60947-2 and UL489 standards and can be used for industrial purposes. Numerous approvals make it suitable for use worldwide and the extensive range of accessories makes it even more convenient to use. Thanks to the very fast arc extinguishing, your installation is optimally protected with the S800U.
