Circuit breakers are designed to withstand vibration. They meet the IEC60068-2-6 standard for vibration:
2 Hz to 25 Hz with an amplitude of +/- 1.6 mm (+/- 0.06 in.)
25 Hz to 100 Hz at a constant acceleration of +/- 4 g
Conformity tests are carried out in accordance with the IEC60068-2-6 standard, at the levels of severity required by the merchant shipping regulatory bodies (mainly IACS, Veritas, and Lloyd’s).
Excessive vibration can cause tripping, breaks in connections, or damage to mechanical parts.
