Its 220 kA breaking capacity at 240 VAC handles high-fault-current scenarios like transformer secondaries or large motor control centers, while the 154 kA at 415 VAC and 121 kA at 440 VAC cover common industrial voltages across global installations.
Rated 32 A continuously at ambient temperatures up to 50 °C, then derates to 30 A at 65–70 °C — a 6% drop across the upper range. That means in a warm panel (say 55 °C) you still get 31 A, so the breaker doesn't force a premature upsize. Maximum power loss is 10.6 W per pole — modest enough that side-by-side mounting in a multi-breaker lineup won't create a hot spot, but still worth factoring into the enclosure thermal budget.
Measures 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON distribution blocks and panelboards without re-drilling the mounting plate. Comes with two built-in HQ auxiliary switches for remote status indication; no ground-fault monitoring module included, so if you need GF protection that's a separate add-on.
Standard catalog item in the SENTRON 3VA line.
