Enhanced Safety Features: The secure RCD connector prevents personal and device damage by detecting residual currents and disconnecting the power supply within 0.1 seconds. It ensures safety with a rated residual current detection of 10 mA and a comprehensive two-pole shut-off mechanism. Broad Compatibility: Designed to work with all European standard plugs, this connector features a test circuit and a reset button. It supports electrical devices operating between 220-250 V AC, up to a maximum of 4000 W, making it suitable for high-demand appliances such as refrigerators, microwaves, and air conditioners. Durable and Portable Design: Constructed from non-conductive, fireproof PC material, this RCD plug is suitable for indoor and outdoor use with an IP44 rating. It operates reliably in temperatures ranging from +40 °C to -25 °C. User Safety Protocol: To ensure optimal protection, plug the adapter into a socket and press the 'Reset' button to activate the device, indicated by a red light. To test functionality, press 'Test' and verify that the power supply is interrupted (the red light turns off). Only use the adapter after a successful test.
