The ground-fault monitoring uses summation current formation on L+N, so it detects leakage without a separate GFCI module — one less device to wire into the enclosure. The 3VA2325-6HM42-0AA0 measures 248 mm high, 184 mm wide, and 110 mm deep — a 4-pole frame that occupies roughly 7.24 inches of DIN-rail width. Mounting is standard SENTRON 3VA screw-clamp to the backplane or DIN rail adapter; verify the existing panel's busbar drilling pattern if replacing a different brand's 4-pole MCCB, since the terminal centers may differ. ## Thermal performance and derating That is unusual for a molded case breaker; most competitors start tapering above 50 °C. ## Protection and release features This is a line-protection design — no undervoltage release, no voltage trip, no communication module onboard. The trip unit is set with an initial value of 50 A and a full-scale value of 250 A, so it is field-adjustable within that range. No trip indicator is fitted; fault events are signaled only by the handle position and downstream monitoring. The insulation voltage rating is 800 V, giving margin above the 690 V interrupting rating.","metaTitle":"Siemens SENTRON 3VA2325-6HM42-0AA0 MCCB, 250 A, 4-Pole, 242","metaDescription":"Siemens SENTRON 3VA2325-6HM42-0AA0 molded case circuit breaker. 250 A continuous, 4-pole, 242 kA at 240 V.

The 3VA2325-6HM42-0AA0 is a higher-current frame (250 A vs the 3VA2225's lower rating), so verify the busbar ampacity and lug size before swapping — the physical dimensions may differ between frame sizes."},{"question":"What compliance documentation does Siemens provide for this MCCB?","answer":"As a SENTRON series MCCB, it carries the standard Siemens declarations — RoHS, REACH, and IEC 60947-2 compliance documentation are available through the manufacturer's support portal.
