That means it's a fixed-trip breaker for standard distribution panels, not a field-adjustable electronic trip. Breaking capacity is the headline here: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 500 V and 690 V. That's a high-interrupting rating for a 50 A frame — it clears a 52.5 kA fault at 240 V without external fuses, which matters when the panel sits close to a large transformer or in a high-fault industrial distribution. Power loss maxes at 14.6 W — modest for a 50 A MCCB, so heat buildup in a crowded enclosure is manageable. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that drops into most DIN-rail or panel-mount enclosures without gland-plate rework. The width is exactly 3 inches (76.2 mm), which matches the typical 3-inch per-pole spacing for busbar stabs in SENTRON distribution boards. The thermal derating curve is tight: full 50 A up to 50 °C, then 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. ## What's in the box — and what isn't It does accept up to 4 auxiliary switches (HQ type) if you need status feedback, but those are ordered separately. No trip indicator, no voltage trigger — it's a bare-bones line-protection MCCB.","metaTitle":"Siemens 3VA1050-2ED36-0AE0 SENTRON MCCB, 3-Pole, 50A, 52.5kA","metaDescription":"Siemens 3VA1050-2ED36-0AE0 SENTRON molded case circuit breaker, 3-pole, 50A rated at 40°C, 52.5kA breaking at 240V.
