The C40R36E400 refers to a model of Schneider ComPacT NSX series interruttore automatico scatolato. Square D, its manufacturer, belongs to Schneider Electric, so this model is essentially a Schneider circuit breaker product. Here is a detailed breakdown of its model parameters and related information:
- Specific model corresponding information
It corresponds to the specific specification of the ComPacT NSX400R molded case circuit breaker. The key performance parameters are as follows: it is applicable to AC circuits, configured with a Micrologic 6.3E electronic trip unit, has a rated current of 400A, and adopts a 3P3D pole configuration (3-pole structure with leakage protection function). Its breaking capacity reaches 200kA under the condition of 415V AC voltage, which can effectively resist the impact of short-circuit current in the circuit.
- Reference for model code implication
Although Schneider has no public official interpretation of the C40R36E400 code, we can infer the meaning of each segment by referring to the coding rules of the same series of models such as C40N36E400 and C40H36E400 :
| Code segment | Implication inference |
| C40 | It is related to the 400A specification of the NSX series. Per esempio, C40N36E400 corresponds to NSX400N, which can be understood as the core code marking the 400A shell frame level of the NSX series. |
| R | Represents the breaking capacity grade of the circuit breaker. Combined with the parameter information of this model, the “R” here corresponds to a breaking capacity of 200kA, which is a higher breaking capacity grade in the NSX series. |
| 36 | It is inferred to be the matching code of the Micrologic 6.3E trip unit. Similar models such as C40N36E400 are all equipped with the Mic6.3E trip unit, which verifies that this code segment is closely related to the type of the trip unit. |
| E400 | IL “E” is likely the feature code of the electronic trip unit. IL “400” directly indicates that the rated current of the circuit breaker is 400A, which is consistent with the rated current parameter marked by the model. |
- Product positioning reference
The NSX series to which this model belongs is Schneider’s core molded case circuit breaker product line. This model, with its 400A rated current and 200kA high breaking capacity, is usually used in scenarios such as industrial power distribution systems, large – scale commercial building power distribution cabinets, and key equipment power protection. It can provide reliable overload, short – circuit and leakage protection for the circuit, and the equipped Micrologic 6.3E trip unit also supports more precise protection parameter adjustment and electrical parameter measurement, which is suitable for medium and high – end power distribution scenarios with high safety and stability requirements.
