Small electrical parts fail in the most frustrating ways: intermittently, under specific conditions, and always at the worst possible time. Diagnosing them takes patience and a meter. Replacing them is the easy part; finding out which one is the problem is the hard part.
This is the genuine Nilfisk Advance OEM 4A CIRCUIT BREAKER, part number VV81342, brand new in the box. Once you've narrowed it down, get the genuine replacement — same contact ratings, same certifications, same interchangeable geometry. Aftermarket electrical parts are how "fixed" turns into "broken again in three months."
