The interrupting rating drops from 187 kA at 240 V to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and 4.5 kA at 690 V. Thermal derating is linear from 55 °C upward: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, 200 A at 70 °C. Below 55 °C, the full 250 A holds. Ambient in the panel matters — a hot enclosure derates the breaker before it trips on overload. ## Ground-fault and communication Ground-fault monitoring uses summation current formation on the L + N conductor — it sees the vector sum, not a separate sensor. The communication function allows remote monitoring or trip indication, though the trip indicator itself is not fitted on this variant. No undervoltage release or voltage trigger is included.","metaTitle":"Siemens 3VA2225-5JQ42-0AA0 SENTRON MCCB, 250 A, 4-Pole, 187","metaDescription":"Siemens 3VA2225-5JQ42-0AA0 SENTRON molded case circuit breaker, 250 A continuous, 4-pole, line protection.
