That means in a tightly packed panel with elevated internal temperature, the continuous current capability is still over 110 A — useful for derating headroom without upsizing the frame. At 25.4 mm wide (1 inch), 130 mm tall, and 70 mm deep, this single-pole MCCB occupies a standard 1-module width on a DIN rail. The SENTRON series carries UL, CSA, and IEC certifications standard for the 3VA platform. RoHS and REACH compliance documentation is available through the manufacturer's support portal.","metaTitle":"Siemens 3VA1112-5ED12-0AA0 SENTRON MCCB, 1-Pole, 125 A, 121","metaDescription":"Siemens SENTRON 3VA1112-5ED12-0AA0 molded case circuit breaker, 1-pole, 125 A, TM210 release, 121 kA at 240 V.
