250 A MCCB with high interrupting capacity for line protection
The Siemens SENTRON 3VA2225-6JP32-0BA0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous current across the 40 °C to 50 °C ambient range, meaning it holds its full rating without derating in most standard panel environments. Above 50 °C it derates linearly to 200 A at 70 °C — a curve to check if the breaker sits near a heat source or in a high-ambient enclosure. Its interrupting capacity hits 242 kA at 240 V and 187 kA at 415 V and 440 V, which places it in the high-fault tier for industrial switchboards and data-center distribution.
Sourcing and lifecycle — active production, quoted to order
Rated for line protection (not motor protection — no thermal-magnetic curve for overload), this MCCB is designed for feeder and distribution circuits where the trip curve coordinates with downstream breakers. The communication function is present, so it can integrate with a higher-level monitoring system if the optional communication module is added.
