Interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and still 75.6 kA at 500 V, which puts it in the high-fault category for industrial mains or transformer-fed sub-distribution. Occupies standard MCCB panel-mount cutout; front IP40 means the operator interface is protected against solid objects over 1 mm but not sealed against moisture — keep it inside an IP54 or better enclosure in washdown areas. ## Installation environment","metaTitle":"Siemens 3VA2025-5HN42-0AA0 SENTRON MCCB, 25A 4P, 300A frame,","metaDescription":"Siemens 3VA2025-5HN42-0AA0 SENTRON molded case circuit breaker, 25A continuous, 4-pole, 300A frame, 187kA at 240V.
