Residual Current Device (RCD) iID-25-4-30-A 25A 4-pole 30mA type A A9Z21425

Residual Current Device (RCD) iID-25-4-30-A is a key element ensuring safety in electrical installations. The device, catalog number A9Z21425, protects against electric shock by effectively disconnecting the circuit when a leakage current to earth is detected. Its four-pole design and rated current of 25A make it suitable for protecting extended circuits.

This model is characterized by its high efficiency thanks to a 30mA sensitivity and Class A, which means it responds to sinusoidal and pulsating leakage currents. The short-circuit strength of 10kA guarantees reliability even in the event of short circuits in the installation.

Design and functionality for professionals:

• Double terminals: Allow connection of two wires of different cross-sections (up to 35 mm² for solid wires and 25 mm² for stranded wires), increasing flexibility during installation.
• Visi-Trip indicator: An optical trip indicator (white-red) allows for quick identification of the device status and causes of potential failures.
• Removal without removing the busbar: The ability to remove a single RCD without disconnecting the entire busbar significantly simplifies service and modernization work.
• Easy mounting/dismounting: Removal from the DIN rail is done without tools, saving time and making the installer's job easier.
• Functionality testing: The possibility of a one-time annual functionality test with the "T" control button (for the first 7 years of use) ensures the correct operation of the device.
• Convenient busbar arrangement: Placing the N bus on the left side facilitates busbar arrangement with overcurrent circuit breakers, improving readability and organization in the distribution board.

Application and benefits for the end user:

The iID-25-4-30-A RCD provides comprehensive protection for the electrical installation in a home or company. Its task is to minimize the risk of electric shock and prevent damage to equipment caused by overvoltage or short circuits. Thanks to its high sensitivity (30mA), it provides effective protection even against small leakage currents that can be dangerous to health. The rated current of 25A allows for the protection of most standard electrical circuits in residential and commercial buildings. The device operates at temperatures from -25°C to 60°C, guaranteeing reliability in various environmental conditions. The IP20 degree of protection provides protection against finger contact and against solid objects larger than 12.5 mm.
