The moulded case circuit breaker MCCB can automatically cut off the current after the current exceeds the trip setting. Moulded case refers to the use of plastic insulators as the casing of the device to isolate conductors and grounded metal parts. Moulded case circuit breakers MCCB typically contain thermal magnetic trip units, while larger models have solid state trip sensors. The trip unit is divided into: thermal magnetic trip and electronic trip. MCCB Commonly used rated currents are as follows: 16, 25, 30, 40, 50, 63, 80, 100, 125, 160, 200, 225, 250, 315, 350, 400, 500, 630A.
