Maximum power loss is 37.5 W, which factors into enclosure thermal calculations. ## Motor Protection and Release Configuration This is the motor protection version of the 3VA2 frame, meaning the ETU350M release is set up for the higher inrush and thermal memory that motor starting demands.","metaTitle":"Siemens 3VA2325-5MN32-0AF0 SENTRON MCCB, 250 A, 3-Pole, ETU3","metaDescription":"Siemens 3VA2325-5MN32-0AF0 SENTRON 3-pole MCCB, 250 A rated continuous current, ETU350M release, 187 kA at 240 V.
