The 3VA1150-3EF36-0AA0: Rated 50 A continuous at 40 °C ambient, it derates to 45 A at 70 °C — the full thermal curve is on the nameplate, so panel builders should account for internal enclosure temperature rise when sizing. Breaking capacity hits 75.6 kA at 240 V AC, dropping to 52.5 kA at 415 V and 11.9 kA at 690 V — the 240 V figure is the one to match against the available fault current at the service entrance.
Dimensions and panel fit
At 70 mm deep, 76.2 mm wide, and 130 mm tall, this MCCB fits standard SENTRON 3VA panel cutouts and busbar arrangements; the 3-pole width matches the 76.2 mm (3 in) footprint common across the series. IP40 protection on the front face means it is suited for enclosed distribution boards — not for washdown zones or outdoor exposure without an additional enclosure.
Lifecycle and sourcing
Marked as current production — this is a standard-catalog SENTRON MCCB, not a phase-out or NRND line item.
