Interrupting capacity is the headline here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 4.5 kA at 690 V. The 690 V figure of 4.5 kA is more modest, so if your application is a 690 V distribution board, verify the SCCR coordinates with your upstream transformer.","metaTitle":"Siemens 3VA1220-5MH32-0AA0 SENTRON MCCB, 200 A, 3-Pole, TM12","metaDescription":"Siemens SENTRON 3VA1220-5MH32-0AA0 molded case circuit breaker, 200 A rated, 3-pole, TM120M release.
