The 250 A frame with those short-circuit ratings means it can sit upstream of smaller branch breakers in a high-fault panel, provided the coordination study confirms the let-through energy is within the downstream devices' withstand. The thermal-magnetic TM220 release gives fixed thermal and magnetic trip points — no interchangeable trip units, so the 250 A rating is what you order. Current rating holds at 250 A up to 50 °C ambient, then derates to 243.3 A at 55 °C, 236.5 A at 60 °C, 229.8 A at 65 °C, and 223 A at 70 °C. If the panel ambient runs at 60 °C, the usable continuous current drops to 236.5 A — size the load accordingly. Maximum power loss is 57 W at rated load — factor that into the panel's thermal budget if the breaker is enclosed with other heat sources.","metaTitle":"Siemens 3VM1225-5EE32-0AA0 SENTRON MCCB, 250 A, 3-Pole, TM22","metaDescription":"Siemens 3VM1225-5EE32-0AA0 SENTRON molded case circuit breaker, 250 A, 3-pole, TM220 release, 70 mm depth.
