The Siemens SENTRON 3VA2225-6HM32-0AA0 is a 3-pole molded case circuit breaker rated for 250 A continuous current, designed for line protection in distribution panels. Its 86 mm depth and 105 mm width fit standard MCCB mounting footprints in switchgear assemblies.
Breaking capacity and selectivity
Breaking capacity is 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 4.5 kA at 690 V. The 242 kA at 240 V gives headroom for high-fault utility feeds; the sharp drop to 4.5 kA at 690 V means this frame is not sized for 690 V main service — it's a 480 V class breaker. The 250 A continuous rating holds flat from 40 °C to 50 °C, then derates linearly to 213 A at 70 °C.
Integration note
Mounts in a standard MCCB panel cutout. The 3-pole form factor with 105 mm width and 181 mm height matches the SENTRON 3VA family footprint. No undervoltage release or communication function on this variant — it's a straight thermal-magnetic line-protection device. Trip indicator is not fitted.
