At 40 °C ambient it carries 80 A continuous; the thermal-magnetic trip holds that rating across the 40–50 °C band without derating, then steps down to 74 A at 70 °C (the operating maximum). The interrupting capacity is what decides the fit: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. That 121 kA at 240 V means it handles high-available-fault panels common in North American commercial services; the 75.6 kA at 415 V covers European industrial distribution where the transformer is close to the switchboard. ## Auxiliary and release configuration — what ships inside This variant ships with an undervoltage release (UVR) and a factory-fitted auxiliary switch block: two auxiliary switches plus one trip alarm switch (HQ type). The UVR means the breaker opens when control voltage drops below a threshold — common on safety circuits or emergency-stop chains where loss of control power must trip the load. The auxiliary switches provide status feedback to a PLC or panel lamp; the trip alarm switch signals only on a fault trip, not on manual switching. Rated insulation voltage is 800 V, so the auxiliary contacts are rated for 690 V line-to-line switching without additional isolation. ## Mounting dimensions and panel fit Footprint is 76.2 mm wide × 130 mm tall × 70 mm deep — the width is three standard 25.4 mm module slots, so it occupies three positions on a DIN rail or panel-mount busbar system. Depth of 70 mm means it clears most 200 mm deep enclosures with room for wiring gutters. The 21.7 W maximum power loss at full load should be factored into the enclosure thermal budget; in a sealed cabinet with multiple breakers, that heat adds up.","metaTitle":"3VA1080-4ED36-0DH0 SENTRON MCCB, 80A, 3-Pole, 121kA at 240V","metaDescription":"Siemens SENTRON 3VA1080-4ED36-0DH0 molded case circuit breaker, 80A rated at 40°C, 3-pole, 121kA breaking capacity at 240V AC.
