SENTRON 3VA1180-5EF32-0AB0 — 80 A MCCB, 3-Pole, High Interrupting Capacity
Interrupting capacity is the headline here: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. That high-fault rating at 240 V makes it a strong candidate for large commercial or industrial services where available fault current exceeds 100 kA — a common requirement in North American 277/480 V panels with high transformer kVA. Current rating holds at 80 A 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. If the breaker sits in a warm enclosure — near other heat sources or in a non-climate-controlled electrical room — use the 70 °C column for continuous-load sizing.
Panel Fit and Mounting
Dimensions are 130 mm high, 76.2 mm wide, and 70 mm deep. The 76.2 mm (3 in) width is the standard 3-pole MCCB footprint for SENTRON 3VA frames — it drops into the same mounting cutout as other 3VA breakers of this frame size, so a panel laid out for a 3VA1110-5ED36-0AC0 will accept this unit without re-drilling. Power loss is 19.2 W maximum at rated current — a moderate figure for an 80 A MCCB. In a densely populated panel, that heat adds to the enclosure's internal temperature rise; factor it into the thermal derating above.
