ABB MCB Breaker retainer clip (S series)

## Purpose
For some reason when ABB designed [these](https://new.abb.com/products/2CDS253001R0164/miniature-circuit-breaker-s200-3p-c-16-ampere) breakers they made the din rail retainer clip to fragile. The breakers can hold one retainer clip per pole, but a 63 AMP 3-Pole breaker only comes with a single nylon retainer clip. When you attempt to torque down the 6 AWG wire in the terminal on the side of the breaker opposite of the clip, the clip often breaks. Then you have a $60 paperweight.
