What this 3VA1080-3ED36-0BC0 brings to the panel
Breaking capacity is where this MCCB earns its keep: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and still 7.5 kA at 690 V. At 415 V that's well into the high-fault range for industrial distribution — it'll clear a bolted fault on a 2 MVA transformer secondary without drama. The 80 A rating holds flat from 40 °C through 50 °C (no derating needed in a warm panel), then tapers gently to 72 A at 70 °C.
Fit and integration — DIN rail or panel mount
Footprint is 76.2 mm wide (about 4.5 standard DIN-modules), 130 mm tall, 70 mm deep — it'll drop onto a DIN rail or bolt into a mounting plate. The 3-pole block has the undervoltage release (UVR) already fitted from the factory, plus two HQ auxiliary switches for status feedback to the PLC or annunciator panel. Front protection is IP40 — fine inside a closed enclosure, not for washdown areas.
