The circuit-breaker is supplied with single-tang terminals (IEC/UL Figure 58 UL and Figure 59 UL) or multi-
tang (only for IEC Figure 60 IEC and Figure 61 IEC).
Changing from horizontal to vertical and vice versa can be achieved at any time with these rear terminals,
with the exception of versions E4.2 UL 2500A and 3200A. Tighten the M8 screws with tightening torque =
