Its interrupting capacity hits 121 kA at 240 V and 75.6 kA at 415 V — numbers that matter when you're coordinating downstream breakers and need a fault-current cliff that won't cascade upstream. The 3VA1080-4ED36-0AE0 ships with four auxiliary switches (HQ version) already fitted — no separate order for a signal contact. That's a complete kit for the panel builder: the breaker, the TM210 release, and the aux contacts in one carton. No holes in the box. Front IP40 protection handles typical panel environments. The unit is 70 mm deep, 76.2 mm wide, and 130 mm tall — standard 3-pole MCCB footprint for DIN-rail or screw-mount integration. ## Thermal derating and temperature range At 55 °C it derates to 76.8 A, then 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C.","metaTitle":"Siemens 3VA1080-4ED36-0AE0 SENTRON MCCB, 80 A, 3-Pole, 121 k","metaDescription":"Siemens 3VA1080-4ED36-0AE0 SENTRON molded case circuit breaker, 80 A rated continuous current, 3-pole, 121 kA breaking capacity at 240 V.
