The 187 kA at 240 V rating is typical for high-fault-capacity panelboards fed close to a transformer; the 4.5 kA at 690 V is a lower but still serviceable interrupt rating for 690 V industrial systems. ## Ground-fault monitoring and auxiliary functions This variant includes ground-fault monitoring via summation current formation on the L-conductor — it detects residual currents by summing the phase currents, not via a separate neutral CT. No undervoltage release, no communication function, and no voltage-trip trigger are fitted on this order code. Maximum power loss is 48 W, which matters for enclosure thermal calculations when grouping multiple breakers in a closed panel. ## Physical fit and environmental range Dimensions: 181 mm height, 105 mm width, 86 mm depth. These cover most indoor industrial environments and unheated warehouses. Lifecycle status is current production — this order code is an active catalog item in the SENTRON 3VA family, not subject to phase-out or last-time-buy as of the latest manufacturer record.","metaTitle":"Siemens 3VA2225-5HM32-0AA0 SENTRON MCCB, 250 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2225-5HM32-0AA0 molded case circuit breaker, 250 A rated, 3-pole, line protection.
