This MCCB delivers 242 kA at 240 V, 187 kA at both 415 V and 440 V, 121 kA at 500 V, and 4.5 kA at 690 V. ## Thermal derating — the real-world current you can count on Above that: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. For a panel that sees 55 °C ambient (common in sealed enclosures or near heat sources), you lose 12 A — plan your load margin accordingly. ## Mounting and integration — panel fit and connections Dimensions are 181 mm height, 105 mm width, 86 mm depth. The shunt trip release (STL) is built in, so you can wire a remote trip from an E-stop or safety relay without adding an external module. Communication function is present on this variant, meaning it can report status or accept remote commands over a bus — check the specific protocol (PROFIBUS, PROFINET, or Modbus) against your control network.","metaTitle":"Siemens 3VA2225-6KQ32-0KA0 SENTRON MCCB, 250 A, 3-Pole, 242","metaDescription":"Siemens SENTRON 3VA2225-6KQ32-0KA0 molded case circuit breaker, 250 A rated, 3-pole, 242 kA breaking capacity at 240 V AC.
