Product details

What the 200 kA breaking capacity means for your panel

The C40R36M320 is a Schneider Electric ComPacT NSX400R molded case circuit breaker (MCCB) from the ComPacT NSX range, rated 320 A at 65 °C with a MicroLogic 6.3 E-M electronic trip unit. The 200 kA holds at 220/240 V, 380/415 V, and 440 V; it derates to 80 kA at 500 V and 45 kA at 690 V, so verify the line-to-line voltage at the installation point.

Protection logic and trip unit

The MicroLogic 6.3 E-M is an electronic trip unit with four protection functions: L (long-time overload), So (short-time short-circuit with adjustable delay for selectivity), I (instantaneous short-circuit), and G (ground fault). Motor tripping classes 5, 10, 20, and 30 are selectable, meaning it can also serve motor branch circuits where the inrush current profile matches a class 10 or 20 starter.
