What this part is
The C113050LS is a Schneider Electric ComPacT NSXm switch disconnector — 3 poles, 50 A rated, 690 V AC, built to EN/IEC 60947-1 and EN/IEC 60947-3. It's a fixed-mount unit with a toggle handle, a visible break indicator, and EverLink terminals that take up to 95 mm² rigid copper or aluminum.
What the ratings mean for your panel
The 50 A rating in AC-22A and AC-23A utilization categories means this disconnector handles both resistive and moderately inductive loads (AC-22) and high-inrush loads like motor switching (AC-23) at full current. The 690 V AC operational voltage gives you headroom on 400 V or 480 V systems without derating. Short-circuit making capacity is 1.28 kA as a standalone unit, but jumps to 150 kA when paired with an upstream breaker — that's the coordination figure a panel builder needs for selective coordination studies.
Where this goes in the line
It snaps onto a 35 mm symmetrical DIN rail or mounts on a backplate — the 81 mm width and 137 mm height fit a standard distribution panel footprint. Pollution degree 3 (IEC 60664-1) means it's rated for industrial environments with conductive dust or occasional condensation, so it holds up in a motor control center or a factory-floor panel. IP40 front face and IK07 impact resistance handle accidental tool bumps without cracking the enclosure.
