MCCB for line protection — 80 A, 3-pole, high interrupting capacity
Its interrupting capacity reaches 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — figures that cover most industrial service-entrance and feeder applications where high fault current is expected.
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard SENTRON 3VA footprint that mounts on DIN rail or panel-mount adapter. The 3-pole width occupies roughly three 18 mm module spaces.
Thermal derating and trip features
The breaker holds full 80 A rating from 40 °C through 50 °C, then derates to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C.
