The interrupting ratings climb to 121 kA at 240 V and 75.6 kA at 415 V, which gives you solid fault-clearing headroom for high-available-fault panels. Mounts on a standard DIN rail — the 76.2 mm width (3 in) and 70 mm depth (2.76 in) fit a compact enclosure footprint. The supplied basic switch is 3VA10804ED360AA0; the auxiliary switch block carries 2 auxiliary switches plus 1 trip alarm switch (HQ), and the shunt trip (STL) is pre-installed. Ambient operating range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. The current rating holds steady at 80 A up to 50 °C, then derates linearly to 74 A at 70 °C — useful data for a hot panel or a summer peak load.","metaTitle":"Siemens 3VA1080-4ED36-0KH0 SENTRON MCCB, 80A, 121kA at 240V","metaDescription":"Siemens SENTRON 3VA1080-4ED36-0KH0 molded case circuit breaker, 80A rated, 121kA interrupting at 240V, 3-pole, line protection.
