päällepoiskytkimistä
Päällepoiskytkimet, often translated as "overload relays" or "thermal overload devices," are crucial safety components in electrical systems. Their primary function is to protect electric motors and other electrical equipment from damage caused by overcurrent conditions, which can arise from various faults such as mechanical overload, phase loss, or short circuits.
These devices operate by sensing the current flowing through the protected equipment. They typically utilize bimetallic
Päällepoiskytkimet are designed to have a time-delay characteristic, meaning they don't trip instantly on brief, harmless
