Lookup label: RCC
Drawing use: Schematic
Reference families: Manufacturer

Representation: Functional block
Installation focus: switchgear
Input: Remote control command
Output: Remote close request

Identifies a supervisory closing request received from the control system.

## In plain English

### What this block does

Identifies a supervisory closing request received from the control system.

### A simple example

In a switchgear bus-coupler panel, a close request is checked against position, mechanism readiness and the selected live-bus or dead-bus conditions before the closing circuit is enabled. For this reference, the drawing identifies “Remote control command” at the input and “Remote close request” at the output. Communication success does not prove breaker movement.

### What the drawings help you do

Start at the named input: Remote control command. Identify its source device or document and the state represented on the drawing. Follow the named output: Remote close request. Cross-reference its destination and separate the command from confirmation that the equipment responded.

### Terms

- Input: Remote control command
- Output: Remote close request
- Application reference: An explanation of a named drawing function or circuit relationship; the project documents define the equipment and its connections.

## What it represents

Identifies a supervisory closing request received from the control system. A closing circuit combines an operator or automatic request with the conditions that allow the breaker to close. The closing coil releases stored mechanism energy where that construction is used; it is different from the spring-charging motor.
In a switchgear bus-coupler panel, a close request is checked against position, mechanism readiness and the selected live-bus or dead-bus conditions before the closing circuit is enabled. For this reference, the drawing identifies “Remote control command” at the input and “Remote close request” at the output. Communication success does not prove breaker movement.
Follow request, permission and final coil output as separate signals. A permissive diagram must say which conditions block closing and what happens if a feedback signal becomes unavailable. The functional block is an independent explanation of this named application. Equipment-specific ratings, terminal connections and operating conditions must be established in the project documentation.

## How to read it

- Start at the named input: Remote control command. Identify its source device or document and the state represented on the drawing.
- Follow the named output: Remote close request. Cross-reference its destination and separate the command from confirmation that the equipment responded.
- Communication success does not prove breaker movement.
- Follow request, permission and final coil output as separate signals. A permissive diagram must say which conditions block closing and what happens if a feedback signal becomes unavailable.

## Information to show or reference

- Label the source and connection reference for remote control command.
- Identify the destination and defined state of remote close request.
- Record the equipment or control-document revision supporting this functional block.
- Check this application limit in the project design: Communication success does not prove breaker movement.

## Important distinction

Communication success does not prove breaker movement. This reference describes the named application; it does not establish a new IEC graphical symbol, an ANSI device-function number or an exact manufacturer connection diagram.

## Facts

- Representation: Functional block
- Installation focus: Switchgear
- Input / boundary: Remote control command
- Output / connection: Remote close request
- Lookup label: RCC is a library lookup label, not a standard device designation.
