Normally, a circuit breaker latch is unlikely to be lost or broken, but anything is possible...
This spare part will find its application especially in secondary vocational schools focused on electrical engineering, where students use components such as circuit breakers repeatedly in practice work and thus risk damaging them. Fixing the circuit breaker to a DIN rail is then not possible and it would be a shame to throw it away or not use it because of banality.
I recommend printing the model with the supports provided. Infill: grid, min. 50%; number of perimeters: 3; layer height: 0.1 mm or lower.
The author marked this model as their own original creation.
