The SOL40N3E160 is a 3-pole EasyPact Solar MCCB from Schneider Electric, rated 160 A at 40 °C with a 50 kA breaking capacity at 800 V AC. If your panel runs hotter, you'll need to derate — the electronic trip allows some adjustment, but the base rating is at 40 °C. The 800 V AC operational voltage (50/60 Hz) per IEC 60947-2 suits 480 V and 600 V class systems with headroom, and the 1250 V rated insulation voltage means the internal clearances handle the transients on ungrounded solar arrays.
Deployment context
This breaker is designed for backplate mounting — fixed, not plug-in. The 40 mm connection pitch and front-facing screw terminals make busbar and cable landing straightforward in a distribution panel. IP20 finger-safe protection means the front is touch-safe, but the terminals need to be inside an enclosure. Pollution degree 3 (IEC 60664-1) means it's rated for conductive pollution environments typical of industrial panels, not just clean office air. Mount it horizontally or vertically — both orientations are allowed per the spec. The toggle control gives a clear visual indication of the contact position, and the suitability for isolation (per IEC 60947-2) means you can use it as a disconnecting means for safe maintenance access.
What's in the box and documentation
Standards compliance covers EN/IEC 60947-1, 60947-2, and 60947-2 Annex H (the solar-specific annex for DC applications).
