Interrupting capacity is the headline here: 242 kA at 240 V, 187 kA at both 415 V and 440 V, 121 kA at 500 V, and still 6 kA at 690 V. The 250 A frame stays fully rated across the 40 °C to 50 °C ambient band; derating starts at 55 °C (241 A) and drops to 213 A by 70 °C.
Trip unit and release configuration
The shunt trip (STL) is integrated, not an add-on module, and its part number is 3VA9688-0BL32. No undervoltage release, no phase-failure detection, no ground-fault module on this variant. The base switch itself is order code 3VA2225-6HL32-0AA0. Maximum power loss is 48 W. Mechanical endurance is 20,000 operations.
Three-pole footprint, so it occupies a standard MCCB slot in a SENTRON distribution panel or any DIN-rail-mounting enclosure rated for the frame size.
Lifecycle status is current — this is an active, in-production Siemens SENTRON catalog number.
