The Siemens 3VA2225-6JP32-0JA0 is a 3-pole SENTRON molded case circuit breaker rated for 250 A continuous current at 40 °C, with a maximum interrupting capacity of 242 kA at 240 V AC. At 415 V and 440 V it still holds 187 kA, and at 500 V it interrupts 121 kA, so it handles industrial distribution panels fed by large transformers. The 250 A continuous rating is the same from 40 °C through 50 °C (–), then derates to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C (–) — so if your panel ambient runs hot, you need to account for that thermal curve, not just the nameplate number.
Line protection design with shunt trip — what that means for your circuit
This breaker is designated for line protection, not feeder or motor-circuit protection. That means it's intended as the main overcurrent device at the origin of an installation or a large subdistribution panel, protecting the conductors and buswork against short-circuit and overload. Communication function is present, which on the 3VA platform typically means it can accept a communication module for PROFIBUS, PROFINET, or Modbus RTU — but that module is ordered separately and mounts onto the breaker's accessory slot.
Physical fit — dimensions and panel integration
The 105 mm width (4.13 inches) per 3-pole unit is standard for SENTRON 3VA molded-case breakers.
