Resettable Differential Gewiss RESTART RD 2P 40A 30mA Class A

The Gewiss RESTART RD 2P 40A 30mA Class A Resettable RCD (reference GWD4827R) is an advanced solution for ensuring 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 the electrical supply after an unexpected trip, once it has verified the safety of the installation, thus preventing prolonged interruptions in the power supply and improving reliability in residential and commercial environments.

Main Features:

• Automatic Reset: In the event that the residual current device trips due to a current leak, the ReStart system automatically checks the status of the installation. If it is confirmed that the conditions are safe, the device automatically restores the power supply, ensuring service continuity without the need for manual intervention.
• Autotest Function: The Gewiss RESTART RD features an Autotest function that automatically and periodically verifies the correct operation of the RCD, all without interrupting the power 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 is capable of detecting alternating current (AC) leaks as well as pulsed direct current (DC) leaks, 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 from 30 mA, offering effective protection against electric shocks from indirect contact and minimising the risk of fires caused by current leaks.
• Nominal Current of 40 A: With a nominal current of 40 A, this RCD is suitable for medium-sized installations typical in homes, offices, or small businesses.
• Standards and Certification: The Gewiss RESTART RD complies with the EN 50557 standard, ensuring adherence to the highest safety and efficiency standards in electrical installation protection. It is also designed to be compatible with TT and TN-S distribution systems.

Key Technical Specifications:

• Nominal AC Voltage: 230 V, compatible with most residential and commercial electrical networks in Europe.
• Number of Poles: 2P, ensuring protection both in the phase and the neutral of the installation.
• Nominal Frequency: 50-60 Hz, suitable for power supply in much of the world.
• Insulation Voltage (Ui): 500 V, ensuring high resistance capacity against voltage spikes.
• Surge Withstand Capacity: With a capacity of 4 kV, the device can withstand transient overvoltages without compromising functionality.
• Nominal Resistance between Live Points and Earth: 16 kΩ, ensuring reliable operation in the event of leakage.
• Overvoltage Category: III, guaranteeing robustness against adverse conditions in low-voltage installations.

Additional Functions:

• Earth Leakage Test: The device performs an automatic earth leakage test to ensure the system does not present issues before resetting after a trip.
• Reset of Unexpected Trips: The RCD is designed to automatically reset after unexpected trips, always verifying the safety of the installation before restoring the power supply.
• Mechanical Resistance: With the ability 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.
• Enhanced 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 RCD is always in perfect working order.
• Easy Installation: With a 3-module format and a compact design, the resettable RCD is easy to install in electrical panels, occupying minimal space and providing an advanced protection solution without complications.
