The interrupting ratings climb to 75.6 kA at 240 V and 52.5 kA at 415 V — numbers that tell you it's sized for high-fault industrial panels, not light commercial. The 4-pole construction means it switches the neutral, which matters for TN-S or IT systems where you need full isolation on all conductors. The 80 A rating holds flat from 40 °C to 50 °C, then starts to taper: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. Plan the load at 72 A if the enclosure hits 70 °C; the breaker won't nuisance-trip, but it also won't carry a full 80 A. This breaker delivers 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. ## Auxiliary contacts and trip alarm — what's wired in The auxiliary contacts follow the main contact position; the trip alarm signals only on a fault trip (overcurrent or undervoltage), not on manual open. That's the contact you'd wire to a PLC input for a shunt-trip or alarm annunciator. No separate UVR module to mount and wire.","metaTitle":"Siemens 3VA1080-3ED42-0CH0 MCCB, 80 A, 4-Pole, 75.6 kA at 24","metaDescription":"Siemens SENTRON 3VA1080-3ED42-0CH0 molded case circuit breaker, 80 A, 4-pole, 75.6 kA at 240 V.
