At 240 V this MCCB interrupts 187 kA, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 7.5 kA at 690 V. These are the short-circuit ratings that govern selectivity with upstream devices — the 187 kA figure at 240 V covers most North American 277/480 V panel applications where the fault current at the main is high, while the 121 kA at 415 V suits European 400 V industrial distributions. The 2 auxiliary switches HQ come pre-installed, saving a wiring pass for status feedback. Rated insulation voltage is 800 V, with operating temperature range -25 °C to 70 °C and storage from -40 °C to 80 °C. Maximum power loss is 37.5 W — factor that into the enclosure thermal budget.","metaTitle":"Siemens 3VA2325-5MQ32-0AC0 SENTRON MCCB, 250 A, 3-Pole, Moto","metaDescription":"Siemens 3VA2325-5MQ32-0AC0 SENTRON molded case circuit breaker, 250 A rated at 40-70 °C, 187 kA at 240 V.
