Gewiss RESTART RD 2P 40A 30mA Class A resettable differential

The Gewiss RESTART RD 2P 40A 30mA Class A rearmable differential (reference GWD4827R) is an advanced solution to ensure the protection of electrical installations, providing not only safety against current leaks but also service continuity thanks to its automatic reset system. This device is designed to restore electrical power after an unexpected trip, once it has verified the safety of the installation, which prevents prolonged interruptions in the power supply and improves reliability in residential and commercial environments.

Main features:

• Automatic reset: In the event that the differential switch trips due to a current leak, the ReStart system performs an automatic check of the installation's status. If it is confirmed that conditions are safe, the device automatically restores the electrical supply, ensuring service continuity without the need for manual intervention.
• Autotest function: The Gewiss RESTART RD features an Autotest function that automatically and periodically checks the proper functioning of the differential, all without interrupting the electrical supply. This system ensures that the device is always in optimal working condition, providing peace of mind to the user and eliminating the need for periodic manual testing.
• Class A differential protection: Designed with Class A differential protection technology, the device can detect alternating current (AC) leakage currents as well as pulsed direct current (DC), making it ideal for applications involving electronic equipment, such as computers, modern appliances, or LED lighting systems.

Safety and performance:

• Nominal differential current: The device is configured to detect differential currents starting from 30 mA, providing effective protection against electric shocks from indirect contact and minimizing the risk of fires caused by current leaks.
• Nominal current of 40 A: With a nominal current of 40 A, this differential switch is suitable for medium-sized installations, typical in homes, offices, or small businesses.
• Regulations and certification: The Gewiss RESTART RD complies with the EN 50557 standard, ensuring that it adheres to the highest safety and efficiency standards in the protection of electrical installations. It is also designed to be compatible with TT and TN-S distribution systems.

Highlighted technical specifications:

• Nominal AC voltage: 230 V, compatible with most residential and commercial electrical networks in Europe.
• Number of poles: 2P, ensuring protection in both the phase and neutral of the installation.
• Nominal frequency: 50-60 Hz, suitable for power supply in much of the world.
• Insulation voltage (Ui): 500 V, ensuring a high resistance capacity against voltage spikes.
• Surge withstand capability: With a capacity of 4 kV, the device can withstand transient overvoltages without compromising its functionality.
• Nominal resistance between live points and earth: 16 kΩ, ensuring reliable operation in case of leaks.
• Surge category: III, guaranteeing its robustness against adverse conditions in low-voltage installations.

Additional functions:

• Ground fault testing: The device performs an automatic ground fault test to ensure that the system does not have issues before resetting after a trip.
• Automatic reset after unexpected trips: The differential is designed to automatically reset after unexpected trips, always verifying the safety of the installation before restoring the electrical supply.
• Mechanical resistance: With a capacity to withstand up to 4000 mechanical operations, the device is built to last and resist wear associated with frequent use.

Applications and benefits:

• Residential and commercial installations: The Gewiss RESTART RD 2P 40A 30mA is ideal for ensuring electrical protection in homes, offices, shops, and small businesses. Thanks to its automatic reset capability, it is especially useful in situations where service continuity is crucial, such as in refrigerators, heating systems, computers, or servers.
• Increased safety: The device ensures that the electrical installation remains safe at all times by performing automatic checks before restoring power after a trip. Additionally, the Autotest function ensures that the differential switch is always in perfect working condition.
• Easy installation: With a 3-module format and a compact design, the rearmable differential is easy to install in electrical panels, taking up minimal space and providing an advanced protection solution without complications.
