Product Overview
The DELIXI CDB6LESi C40 is a 1P+N 40A RCBO designed for single-phase circuits requiring overcurrent, short-circuit and residual-current protection in one DIN-rail device.
The reference unit shown on this page uses a C tripping curve, 30mA Type AC residual-current protection and a rated breaking capacity of 6kA.
The complete reference configuration is: CDB6LESi / 1P+N / C40 / 30mA / Type AC / 6kA
This 40A version should be matched to the actual circuit design, conductor size and connected load rather than selected only by product appearance or series name.
What Buyers Usually Need to Confirm
Before quotation or supplier matching, buyers normally need to confirm:
- required DELIXI series or equivalent model
- 1P+N or other required pole configuration
- rated current
- tripping curve
- rated voltage and frequency
- rated residual operating current (IΔn)
- residual-current type
- breaking capacity
- required certification or technical documentation
- quantity and destination market
For distribution-board or equipment projects, buyers may also provide a panel schedule, single-line diagram or electrical BOM for model matching.
Final breaker selection should follow the project electrical design and applicable local requirements.
