The circuit breakers of the SX 200 series protect cables and lines from 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 easy and secure contact and handling. Up to 2 x 4 mm² conductors can be connected to the upper outgoing Push-In terminal. On the input side, the PSX phase rails can be used for cross-wiring. For power supply, conductor cross-sections of up to 10 mm² can be directly connected to the device via the screw connection terminal in protection class IP20. For better visibility when connecting, the opening of the screw terminal is located above the flexible terminal for the phase rail. Numerous approvals make the SX200 suitable for use in household and commercial applications. Each device undergoes three intensive tests for quality and performance before delivery.
