Lookup label: RCCB
Drawing use: GA, SLD
Reference families: Manufacturer

An RCCB detects residual current and opens its associated circuit, with its function specified independently of overcurrent protection.

## What it represents

An RCCB detects residual current and opens its associated circuit, with its function specified independently of overcurrent protection.
Show its poles and neutral arrangements in the schedule and coordinate test-button access. The GA locates the physical item; the associated schematic or equipment schedule records its electrical interfaces.
The preview is independent educational geometry and is not a manufacturer outline, fabrication drawing or verified standard graphic. Obtain the applicable model drawing from the cited official source before making a dimensional layout.

## How to read it

- Show its poles and neutral arrangements in the schedule and coordinate test-button access.
- An RCCB and an RCBO have different protection combinations; a matching width does not establish interchangeability.

## Information to show or reference

- Confirm the exact equipment identity, drawing revision and installation orientation.
- Show its poles and neutral arrangements in the schedule and coordinate test-button access.
- Cross-reference the terminals, cable routes and service tasks with the equipment schedule.

## Important distinction

An RCCB and an RCBO have different protection combinations; a matching width does not establish interchangeability.
