The circuit breakers in the SX 200 series protect cables and lines against overload and short circuits in accordance with DIN VDE 0100-430 and DIN VDE 0100-530. They comply with the construction regulations DIN VDE 0641-11 and IEC/EN 60898-1. Their patented connection terminals with push-in technology ensure simple and safe contact and handling. Conductors of up to 2 x 4 mm² can be connected to the upper, output-side push-in terminal. On the input side, the PSX phase rails can be used for cross-wiring. For the feed-in, conductor cross-sections of up to 10 mm² can be connected directly to the device via the screw connection terminal in protection class IP20. For better visibility when feeding in, the connection opening of the screw terminal is above the flexible terminal for the phase rail. Numerous approvals make the SX200 fit for use in household and commercial applications. Each device undergoes three intensive tests for quality and performance before delivery.
