That drops to 75.6 kA at 500 V and 11.9 kA at 690 V. ## Auxiliaries and releases No ground-fault monitoring module is included; if you need GF protection, that's a separate accessory. The trip indicator is not fitted, so you won't get a visual flag on the front — factor that into your panel inspection routine.","metaTitle":"Siemens 3VA1332-5EF42-0BB0 SENTRON MCCB, 320A, 4-Pole, 187kA","metaDescription":"Siemens 3VA1332-5EF42-0BB0 SENTRON molded case circuit breaker, 320A at 40°C, 4-pole, 187kA breaking at 240V.
