At 40 °C it holds a steady 200 A continuous rating across the full ambient range up to 70 °C, meaning the breaker does not derate as the panel warms, a real advantage in a crowded enclosure.
Breaking capacity — what those numbers mean for panel coordination
At 500 V the capacity drops to 75.6 kA, and at 690 V it falls to 5.2 kA — a steep derate that tells you this breaker is designed for 240/415 V distribution, not 690 V motor circuits. That margin simplifies selective coordination studies because you can let downstream 18 kA or 25 kA breakers ride through a fault without upstream tripping.
What rides inside — auxiliary switches and releases
The basic switch variant is 3VA2220-5MN32-0AA0, so this -0JH0 suffix adds the shunt trip and the HQ alarm switch on top of the base motor-protection trip unit. No undervoltage release is fitted, and no ground-fault monitoring module is included — those are separate add-on accessories if your application requires them.
Physical fit — panel cutout and mounting
Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint that fits Siemens SENTRON mounting plates and most 200 A panelboard stabs. If you are swapping a competitor's 200 A frame or an older Siemens 3VL breaker, verify the bus-bar slot pitch matches the 105 mm width before ordering — the 3VA2 uses the same bolt-on or plug-in base as other SENTRON 3VA breakers in the same amp class.
