Minimum clearance between the circuit breaker and metal
The clearance between the terminal and the grounded metal must be G ≥ 12 mm.
If the clearance to ground G is < 12 mm, live parts must be insulated or a suitable barrier
must be installed.
CAUTION
Depending on the application, appropriate air and creepage distances must be observed,
e.g. IEC 60439-1.
