The Schneider Electric EVS20H3MF20 is a 3-pole EasyPact EVS circuit breaker rated 2000 A at 40 °C, with a 65 kA Icu breaking capacity at 440 V AC 50/60 Hz per IEC 60947-2. It carries an electronic EVS Trip System2.0 unit providing overload (long-time) and instantaneous short-circuit protection (LI).
If your enclosure runs hotter, expect derating per the manufacturer's thermal curve. Category B utilization (IEC 60947-2) means the breaker is designed for selectivity with downstream devices — it has a deliberate short-time delay capability to let a downstream breaker clear first, keeping supply to healthy circuits. The 20-minute thermal memory before and after tripping means the electronic trip unit remembers the thermal state even after a trip, so re-energizing too quickly won't cause nuisance trips on a still-hot conductor.
Deployment context
The 115 mm connection pitch without spreader matches common busbar drilling patterns for this frame size. Vertical or horizontal connection orientation is permitted, giving flexibility in panel layout.
