MCB connection terminals are designed for the class: "Field wiring" This means that, as well as being installed in a factory, these MCBs can be installed locally at customer sites. In addition to the permissible tripping ranges according to UL 489, device tripping characteristics C and D of EN/IEC 60 898 also apply. Therefore, these MCBs comply with both standards.

Siemens terminal blocks simplify the wiring of machines and system controls and incorporate screw, spring loaded, or insulation displacement connections that meet or exceed the requirements of CSA, IEC, NEMA, UL, VDE and other international standards. Meeting these requirements, combined with worldwide acceptability and availability, enables Siemens terminal blocks to be used domestically and incorporated into equipment intended for export. Virtually all terminal block bodies are insulated on both sides, eliminating the need for barriers and end plates. The materials used are free of cadmium, halogens, or silicone. Except for bare terminals and solder connections, the terminals are finger-touch safe to IEC 60529 and EN 50274. Siemens terminal block lines include the following five connection types.
8WA1 terminals with screw connection 8WH2 terminals with spring loaded connection 8WH3 terminals with IDC connection 8WH4 terminals with push-in connection 8WH5 terminals with combi-plug connection
