WebTrip Curve Trip Curve for a Thermal Magnetic MCCB The most commonly selected form of thermal protection is the bimetallic version. This works similarly to a traditional overload relay in which a bimetallic element is heated, causing a deflection, which then exerts pressure on a trip bar and causes the circuit breaker to trip. Trip Curve WebThe circuit breakers’ tripping curves consist of two parts: - tripping of overload protection (thermal tripping device): the higher the current, the shorter the tripping time - tripping … dealwithyou.com https://lgfcomunication.com
