Miniature Circuit Breakers (MCB) questions
What does the C in a C32 MCB mean?
C is the trip curve. The magnetic release trips between 5 and 10 times the rated current, which suits general loads. 32 is the rated current in amperes.
Can an MCB from one brand sit on another brand's busbar?
DIN-rail mounting is common, but busbars and accessories are brand-specific. Check compatibility before mixing.
Do you supply MCBs in bulk?
