Breaking capacity runs 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V — the 415 V figure is the one that governs most European 400 V distribution panels, and 121 kA gives generous headroom above typical 50 kA or 65 kA fault levels. ## Motor Protection Specifics The breaker is designated as motor protection design, which means its trip curve and thermal memory are tuned for motor inrush and overload profiles — not the same as a standard distribution MCCB. Maximum power loss is 37.5 W, relevant for enclosure thermal calculations when the breaker is enclosed alongside other heat sources. The basic switch variant is order code 3VA2325-5MN32-0AA0, which is the core switching mechanism this assembly builds on. No undervoltage release fitted; no ground-fault monitoring module included — those are separate accessory additions if needed.","metaTitle":"Siemens 3VA2325-5MN32-0KL0 SENTRON MCCB, 250A, 3-Pole, Motor","metaDescription":"Siemens 3VA2325-5MN32-0KL0 SENTRON molded case circuit breaker, 250A rated at 40°C, 3-pole, motor protection design with phase failure detection. 187kA at 240V.
