On my second one and it is broke now too. The plastic seems to always break. First one I chocked up to me getting the screws too tight; I know I didn't make that same mistake on the second one.
For various reasons a Hall current sensor is better https://www.poweruc.pl/products/hal...=1&_sid=834f34193&_ss=r&variant=1961591996460
Clamp on, no bare terminals, eliminates two crimp connections, no issue having to fuse the sense wires, etc. etc.
