The breaker carries a maximum breaking capacity of 187 kA at 240 V, 121 kA at 415 V, and 4.5 kA at 690 V — the 690 V figure is the tail-off point that governs its use on 690 V systems where fault current is low. The headline rating is 250 A continuous at 40 °C, but the breaker is thermally rated across a range: it holds 250 A up to 50 °C, then derates to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. The interrupting ratings span the common industrial voltages: 187 kA at 240 V, 121 kA at both 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. It mounts in a standard distribution panel footprint — the 105 mm width is a 3-pole MCCB form factor that fits Siemens SENTRON busbar systems and panelboards.","metaTitle":"Siemens 3VA2225-5JQ32-0AJ0 SENTRON MCCB, 250 A, 3-Pole, 187","metaDescription":"Siemens 3VA2225-5JQ32-0AJ0 SENTRON molded case circuit breaker, 250 A rated at 40 °C, 3-pole, 187 kA breaking capacity at 240 V.

The -0AJ0 variant includes a communication function and a trip indicator; the -0AK0 may differ in auxiliary switch configuration or electronic trip unit. Physically they occupy the same panel cutout and busbar connection, but verify the auxiliary wiring and trip unit settings against your BOM before swapping — the auxiliary switch count and trip curve may differ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2225-5JQ32-0AJ0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA2225-5JQ32-0AJ0 when reusing this data.
