The Siemens SENTRON 3VA2325-5HN42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for 250 A continuous current at 40 °C, with the same 250 A rating holding steady all the way up to 70 °C — no derating curve to chase across the typical panel ambient range. Breaking capacity is voltage-dependent: 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V.
Panel integration and physical fit
The 184 mm width for a 4-pole frame is standard for this class — verify gland-plate cutout and adjacent device spacing before committing the panel layout. Mount it inside a rated enclosure if the environment is wet or dusty. Maximum power loss is 37.5 W — account for this in enclosure thermal calculations, especially in a densely packed panel.
