The Siemens SENTRON 3VA2440-6HN32-0AE0 is a 3-pole molded case circuit breaker (MCCB) rated for a continuous current of 4800 A across the full ambient temperature range from 40 °C to 70 °C, making it a line-protection device sized for high-current feeders in industrial distribution panels. Its interrupting capacity reaches 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V — figures that define the available fault current it can safely clear without upstream coordination failure.
Sizing and deployment context
Maximum power loss of 63.5 W must be factored into the enclosure thermal budget; the breaker is rated for operation between -25 °C and 70 °C and storage from -40 °C to 80 °C.
