For a 415 V industrial feeder, that 52.5 kA SCCR gives real selectivity headroom against a downstream 25 kA MCCB — you can coordinate without oversizing the main. That's a standard SENTRON 3VA form factor — it occupies the same footprint as other 3VA frame breakers. If you're swapping into an existing panel that was built around a 3VA1010 or similar, the mounting hole pattern and bus-bar spacing are identical; no re-drilling or re-bussing needed. The 76.2 mm width is three 25.4 mm pole pitches, so it aligns with standard 25 mm bus-bar centers. Maximum power loss is 21.7 W. In a sealed, non-ventilated enclosure, that heat has to be factored into the thermal budget — but for a panel with natural convection, it's manageable.","metaTitle":"Siemens 3VA1080-3ED36-0DC0 SENTRON MCCB, 80A, 3-Pole, 75.6kA","metaDescription":"Siemens SENTRON 3VA1080-3ED36-0DC0 molded case circuit breaker, 80A rated, 3-pole, line protection.
