KGB4L Residual Current Circuit Breaker (RCCB)
KGB4L Residual Current Circuit Breaker (RCCB)
KGB4L RCCB supports 2P 230V and 4P 400V circuits with selectable residual operating current. Request technical data and quotation from CANGO.
Buyer Overview
KGB4L is a residual current circuit breaker intended for AC 50/60Hz electrical systems. The current website table lists 2-pole 230VAC and 4-pole 400VAC configurations for earth leakage protection in distribution circuits.
For importer and project selection, the KGB4L page should be evaluated by pole number, rated current and residual operating current. The product is an RCCB and should not be used as overload or short-circuit protection unless separate protection is provided.
Key Features
- 2P 230VAC and 4P 400VAC configurations listed on the original page
- Rated current options of 25A, 40A and 63A
- Residual operating current selections of 30mA, 100mA, 300mA and 500mA
- Operating time listed as no more than 0.1 second
- Symmetrical DIN rail installation
- Original table references IEC61008 and GB16916

Selection Notes
Select KGB4L according to the wiring system first: 2P for the listed 230VAC configuration or 4P for the listed 400VAC configuration.
Choose 30mA, 100mA, 300mA or 500mA only after checking the protection objective and local installation requirements.
Coordinate the RCCB with a suitable upstream or downstream overcurrent protection device because the current page positions KGB4L as residual current protection.
Applications and Installation Notes
Applications
- Residential consumer units requiring earth leakage disconnection
- Commercial distribution boards using 2P or 4P circuits
- Building wiring projects with confirmed residual current settings
- Electrical panel replacement and distributor sourcing
- Low-voltage AC leakage protection installations
Installation Notes
- Install on a symmetrical DIN rail as stated in the product table.
- Verify line and load terminals before energizing the circuit.
- Select a separate protective device for overload and short-circuit protection where required.
- Test procedures and inspection intervals should follow the product instructions and local electrical rules.
