The TM210 thermal-magnetic trip unit gives you fixed thermal and magnetic settings — no field adjustment, no configuration risk, just install and trust the curve. Rated 80 A continuous at 40 °C, it holds that same 80 A all the way up to 50 °C ambient; above that it starts a gentle derate — 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, 74 A at 70 °C. ## Breaking capacity — what it clears At 240 V AC this breaker interrupts 121 kA; at 415 V AC it still clears 75.6 kA. For DC applications, rated operating voltage is 250 V DC; the manufacturer notes that switching power values in DC networks require consulting the 3VA device manual for specific coordination. ## Footprint and panel fit Depth is 70 mm, height 130 mm.","metaTitle":"Siemens 3VA1180-4ED22-0AA0 SENTRON MCCB, 80A, 2-Pole, 121kA","metaDescription":"Siemens SENTRON 3VA1180-4ED22-0AA0 molded case circuit breaker, 80A rated at 40-50°C, 2-pole, TM210 trip unit, 121kA breaking capacity at 240V AC.
