What the breaking capacities mean for panel coordination
Its 121 kA breaking capacity at 240 V AC and 75.6 kA at 415 V AC mean it can interrupt fault currents at those levels without upstream fuses blowing — critical for maintaining selectivity in a multi-level panel where a downstream fault must not take out the main feed. The 52.5 kA at 440 V and 11.9 kA at 690 V cover the higher-voltage end of industrial supplies, though the 690 V figure is notably lower, so check the available fault current at that voltage before committing the BOM line.
Thermal derating and the TM240 release
Above 50 °C the curve drops: 15.36 A at 55 °C, 15.04 A at 60 °C, 14.72 A at 65 °C, 14.4 A at 70 °C. The TM240 overcurrent release is thermal-magnetic, adjustable with a maximum response time tr of 1 second, so it coordinates with downstream breakers on time-current curves.
The 3VA1196-4EF32-0AB0 measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard three-pole MCCB footprint that drops into a SENTRON panelboard or onto a mounting plate without re-drilling.
