The circuit breakers of the S300P series protect cables and lines against overload and short circuit in accordance with DIN0100-430 and DIN0100-530. They comply with the construction regulations DIN0641-11 or IEC/EN 60898-1, DIN0660-101 or IEC/EN60947-2 and UL1077. Their patented connection terminal ensures simple and safe contacting and handling using a pressure plate. Installation and removal on the top hat rail is tool-free and is also possible from the busbar assembly. The circuit breakers have a front-side error display to distinguish between tripping in the event of a fault and manual switching off. The detailed technical documentation can be quickly accessed using a QR code on the front of the device. Numerous approvals and a comprehensive range of accessories make the S300P suitable for worldwide use in demanding applications.
