The circuit breakers in the SU 200 M series protect cables and lines against overload and short circuits in accordance with DIN0100-430 and DIN0100-530. They comply with the construction regulations DIN0660-101 or IEC/EN60947-2 and UL489 or CSA 22.2 No. 5. Their patented connection terminal ensures simple and safe contact and handling using a pressure plate. For better visibility when wiring, the connection opening for lines is above the connection opening for the phase busbar. Conductor cross-sections of up to 35 mm² can be connected directly to the device via the connection terminal with insulation in protection class IP20. The extensive range of accessories offers you everything you need for your installation tasks. The combination of approvals in accordance with UL489, CSA 22.2 No. 5 and IEC/EN60947-2 make this device a worldwide applicable device for high demands and is subjected to three intensive tests for quality and performance before delivery.
