What this MCCB carries and where it fits
The Siemens SENTRON 3VA2225-5HL32-0KG0 is a 3-pole molded case circuit breaker rated for 250 A continuous current at 40 °C through 50 °C — no derating needed in a warm panel up to that point. Above 50 °C the thermal curve steps down: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. The breaking capacity is the headline number for a line protection breaker: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. That 187 kA at 240 V means it can safely interrupt a fault current that high without the arc flashing over to the bus — critical for high-available-fault panels like a main service entrance or a large MCC bucket. It carries a shunt trip (STL) release and one auxiliary switch plus one trip alarm switch, so you get remote trip and status feedback without adding a separate module. No undervoltage release, no ground-fault monitoring, no communication function built in — this is a straight line-protection device meant for a distribution feeder or a large branch circuit.
Panel fit and integration
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — a standard 3-pole MCCB footprint for distribution panelboards and MCC buckets. The shunt trip coil draws from a separate control voltage; verify polarity and suppression on the coil circuit if you are wiring it into a 24 VDC control loop. The auxiliary and alarm switch contacts are rated for typical PLC-level signals (check the specific contact rating in the datasheet). No communication module means no fieldbus wiring — just the power lugs and the control wires for the shunt trip and aux contacts. It is a straight swap into any panel spec'd for a 250 A frame SENTRON breaker.
