No communication function is built in; status is available only through the hardwired auxiliary contacts.","metaTitle":"Siemens SENTRON 3VA2225-5HN42-0DH0 MCCB, 250 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA2225-5HN42-0DH0 molded case circuit breaker, 250 A continuous, 4-pole, 187 kA interrupting at 240 V.
