ReStart Rd PRO 2P
Gewiss GWD0976 ReStart Rd PRO, compatible 2P IDP residual current circuit breaker (RCCB) next to it; checks the insulation condition of the installation before re-energizing and restores power only when safe conditions are met.
SHORT ANSWER
What is the purpose of GWD0976?
Gewiss GWD0976 ReStart Rd PRO, compatible 2P IDP residual current circuit breaker (RCCB) next to it; checks the insulation condition of the installation before re-energizing and restores power only when safe conditions are met.
Important distinction: This product is not the residual current circuit breaker itself; it is an automatic reclosing accessory to be mounted alongside a compatible circuit breaker.

WORKING PRINCIPLE
How does reclosing occur?
- The residual current circuit breaker (RCCB) tripping is detected.
- Accessory checks for earth fault and insulation condition before re-closing.
- If a residual current is detected, the circuit breaker must not be closed and the installation must be monitored every two minutes.
- When safe conditions are met, the compatible switch automatically re-energizes.
APPLICATION AREAS
For which loads is it evaluated?
- Residential and commercial buildings where human intervention may be delayed
- Alarm, modem, server and communication loads
- Cooling and pump systems
- Monitored remote stores, offices, warehouses and facilities
Repeated tripping may indicate a permanent fault in the installation or equipment. Product selection, installation and commissioning should be carried out by a qualified electrician, checking the installation values.
GWD0976 residual current circuit breaker (RCCB) is it?
No. The ReStart Rd PRO automatic reclosing accessory is mounted next to a compatible IDP residual current circuit breaker.
Does the RCCB close the circuit while leakage current is present?
No. It checks the insulation condition before closing again; if there is a leakage, it checks the circuit once every two minutes.
Which circuit breaker is used with?
2P, smart pre-selection residual current circuit breakers (RCCBs) compatible with 30 mA and 80 A are considered; exact code match must be verified from the latest manufacturer documentation.
