* The 10mA VKL11 option applies to published 16–40A configurations. IEC 62423 covers Type F and Type B; a Type B+ claim must be confirmed against the exact variant and applicable DIN VDE 0664-400 evidence. The VKL11-EV catalog lists IEC 62955 for VKL11A-EV, while VKL11F-EV is listed with EN 62423 and OVE E 8601. Confirm the ordered variant and supporting documents.

Turn the circuit requirement into a checkable RCCB specification.
An RCCB should not be chosen from one headline rating. Record the complete electrical requirement and match it to the exact published model.
Open the complete RCCB selection guide- 01
Confirm system voltage and conductors
Define the single-phase or three-phase circuit, neutral arrangement and required 2P or 4P switching.
- 02
Set rated current and IΔn
State both the continuous-current rating and the required residual operating current.
- 03
Match the residual-current waveform
Use the connected equipment manufacturer’s requirements to select Type AC, A, F, B, B+ or an EV variant.
- 04
Coordinate overcurrent protection
Confirm the MCB, fuse or other overcurrent device because an RCCB does not provide overload or short-circuit protection.
- 05
Verify the exact document set
Match the model, rating, standard, destination market, certificate request and OEM artwork before production.

Purchase questions
RCCB sourcing FAQ
Short answers for model selection and document review.
Which VIOX RCCB series should I start with?
Start with VKL11 for Type AC, A or ASi requirements, VKL11F for Type F mixed-frequency loads, VKL11B for Type B or B+ smooth-DC detection, and VKL11-EV for the declared Mode 3 EV charging configurations. Final selection must follow the connected equipment, system design and applicable rules.
Does an RCCB provide overload and short-circuit protection?
No. An RCCB provides residual-current protection and must be coordinated with the required MCB, fuse or other overcurrent protective device. Use an RCBO where combined residual-current and overcurrent protection is required in one device.
What information is needed for an RCCB quotation?
Provide the circuit voltage, rated current, pole configuration, RCCB type, rated residual operating current, quantity, destination market, required documents and any OEM marking or packaging requirements.
Are the same certificates and reports available for every RCCB series?
Documentation must be confirmed for the exact model, rating and destination market. Request the applicable datasheet, declaration, certificate or test document before approving a product for a project or private-label program.
Does VKL11-EV include 6mA smooth-DC detection?
The published VKL11-EV catalog states that the A-EV and F-EV variants incorporate smooth-DC residual-current detection and switch off at a maximum 6mA threshold. IEC 62955 is listed for VKL11A-EV, while VKL11F-EV is listed with EN 62423 and OVE E 8601. Confirm the exact variant and supporting documents before specification.
