The interrupting ratings climb as voltage drops: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. ## Thermal derating — where the 80 A holds and where it tapers At 55 °C it derates to 76.8 A, at 60 °C to 75.2 A, at 65 °C to 73.6 A, and at 70 °C to 72 A. If your panel ambient sits at 50 °C or below, you get the full 80 A without a sizing penalty. Above that, the TM210 release's thermal element responds to the higher ambient — factor the derating into your load calculation rather than oversizing the breaker. The 3VA1080-3ED36-0KA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. No trip indicator on the fascia, so fault indication relies on the shunt trip or a downstream annunciator.","metaTitle":"Siemens 3VA1080-3ED36-0KA0 SENTRON MCCB, 80 A, 75.6 kA at 24","metaDescription":"Siemens SENTRON 3VA1080-3ED36-0KA0 molded case circuit breaker, 80 A rated, 75.6 kA interrupting at 240 V. 3-pole, TM210 release, shunt trip.
