Motor Protection MCCB with ETU350M — Key Ratings for the Panel Designer
The 200 A holds across the 40–50 °C band without derating; at 55 °C it's still 192 A, and it only drops to 180 A by 70 °C — so for most panel environments you get full rating without a sizing haircut. Short-circuit withstand is where this frame earns its keep: 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 17 kA at 690 V.
Undervoltage Release and Auxiliary Contact Complement
The UVR drops the breaker on loss of control voltage — standard for safety circuits where a downstream contactor or safety relay needs to force a trip. The alarm switches give the PLC a hardwired status of the breaker state, separate from the aux contacts that track the handle position. The base switch itself is order code 3VA2220-5MN32-0AA0; this '-0DL0' suffix adds the UVR and the HQ auxiliary block as a factory-assembled variant.
