DELIXI CDB6LESi 3P 40A 30mA RCBO for 400V Circuits

The DELIXI CDB6LESi C40 is a three-pole RCBO designed for 400V three-phase circuits requiring overload, short-circuit and residual-current protection in one modular device.

Its three linked poles operate together across the phase conductors, while the 30mA residual-current function provides additional protection against earth-leakage faults. The reference unit is rated at 40A with C-curve tripping and 6kA short-circuit breaking capacity.

This 3P configuration is intended for systems that do not require a switched neutral pole. JXNUO can match the breaker against the buyer’s panel schedule, single-line diagram or complete electrical BOM before sourcing.

Product Overview

This DELIXI CDB6LESi is a 3P 40A RCBO for 400V three-phase circuits, combining overcurrent and residual-current protection in one DIN-rail device.

The reference configuration uses a C tripping curve, 30mA Type AC residual-current protection and a rated breaking capacity of 6kA.

The complete reference configuration shown on this page is: CDB6LESi / 3P / C40 / 400V / 30mA / Type AC / 6kA

This is a three-pole configuration without a dedicated neutral pole. Buyers should confirm the required pole arrangement against the electrical design, panel schedule or existing breaker reference before ordering.


What Buyers Usually Need to Confirm

Before quotation or supplier matching, buyers normally need to confirm:

  • DELIXI model or equivalent model requirement
  • 3P, 3P+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 project documentation
  • quantity and destination market

For panel 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.
