Its breaking capacity reaches 121 kA at 240 VAC and 75.6 kA at 415 VAC, dropping to 11.9 kA at 690 VAC — figures that tell you where this breaker has the headroom for high-fault installations and where it needs upstream coordination. The TM210 overcurrent release is a fixed thermal-magnetic unit — no interchangeable rating plugs, no electronic adjustments. You set the breaker at 80 A and it stays there. That simplifies ordering but means the trip curve is baked in; if your load profile needs a wider magnetic pickup window, you step to the 3VA11 frame with an electronic trip. At 40 °C the breaker carries a full 80 A. It holds that rating through 50 °C, then begins a gentle taper: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. The case dimensions are 130 mm high, 76.2 mm wide, and 70 mm deep — a 3-pole MCCB that fits standard SENTRON mounting footprints. That's the heat you need to evacuate in a sealed enclosure; if you're stacking multiple breakers in a small gland plate, factor the cumulative dissipation into your thermal analysis. ## Breaking capacity by voltage — where it fits The interrupting ratings span the common distribution voltages: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V.","metaTitle":"Siemens 3VA1080-4ED36-0AA0 SENTRON MCCB, 80 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1080-4ED36-0AA0 molded case circuit breaker, 80 A rated, 3-pole, TM210 trip unit.
