Product details

The Siemens SENTRON 3VA2440-8JP32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 400 A continuous current at 40 °C through 70 °C — no derating needed across that ambient range, which simplifies panel design in warm enclosures. Breaking capacity runs from 440 kA at 240 V down to 52.5 kA at 690 V, so it handles high-fault locations (transformer secondaries, large motor control centers) without cascading upstream.

The 3-pole footprint matches typical switchboard or panelboard cutouts for 400 A class MCCBs.
