What this MCCB carries on the nameplate
Breaking capacity runs 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 — so the SCCR headroom shifts with your system voltage; at 415 V you've got 121 kA to work with, which covers most industrial secondary distribution. Thermal derating starts at 55 °C: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, 200 A at 70 °C. If the panel ambient sits above 50 °C, the continuous current drops — plan the load accordingly. The basic switch itself is order code 3VA2225-5KP32-0AA0.
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — standard 3-pole MCCB footprint for a SENTRON 3VA frame.
The 187 kA at 240 V is the fault current it can safely interrupt at that voltage; at 690 V that drops to 4.5 kA, so verify the available fault current at your system voltage before specifying. Power loss is 50.5 W maximum — relevant for thermal management inside a sealed enclosure.
