The Weg IM1 and IM2 CRB contactor interlocks provide a mechanical means of safety for
reversing and star-delta type starters. The interlocks are designed to be "zero-width",
which means contactors can be mounted side-by-side without any gap or spacing.
The IM1 is for CWB sizes 9 to 38 Amps, and the IM2 is for CWB 40+ amp contactors.
