Breaking capacity hits 187 kA at 240 V, dropping to 121 kA at 415 V and 75.6 kA at 440 V — at 500 V and 690 V it holds at 17 kA. Current derating matters here: it holds 100 A from 40 °C through 50 °C, then drops to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. That's enough for remote status on the breaker position and a separate alarm on trip, which saves an add-on module for basic panel monitoring. It's a straight line-protection MCCB with UVR — clean, no frills, and the trip indicator is present for visual fault confirmation.
Dimensions are 70 mm deep, 76.2 mm wide (3 inches), 130 mm tall. That 76.2 mm width per pole is the standard SENTRON 3VA footprint — it occupies roughly 3 inches of DIN rail or mounting plate width per breaker. No special cutout needed beyond the standard MCCB mounting pattern.
