Residual Current Device (RCD) iID-63-2-30-A 63A 2-pole 30mA type A A9Z21263

Safety and reliability in your electrical installation

This two-pole residual current circuit breaker iID-63-2-30-A is a key element ensuring the protection of people and electrical installations against the effects of leakage and short-circuit currents to earth. Designed by Schneider Electric, model A9Z21263 combines compact size with high efficiency, making it an ideal solution for both professional installers and end users.

Functionality and application

The circuit breaker is designed for mounting on a DIN rail and is characterized by a rated current of 63A and a sensitivity of 30mA type A. This means that it reacts to leakage currents of 30 milliamperes, providing quick protection in the event of a failure. Type A guarantees detection of both sinusoidal and pulsating currents with a DC component, which increases the scope of protection. It will be useful in protecting circuits in residential, commercial and industrial installations.

Construction and parameters

The device is distinguished by a solid construction and high quality workmanship. Its width is only 2 modules (36mm), which allows saving space in the switchgear. The circuit breaker has a mechanical lock, preventing accidental disconnection or connection. It is adapted to work in a wide range of ambient temperatures (-25°C to +60°C) and is characterized by a high rated insulation voltage (500V) and impulse voltage (6kV). The possibility of connecting wires with a cross-section from 1mm² to 35mm² (solid) or 1mm² to 25mm² (stranded) provides flexibility during installation. Additionally, the device offers a current shock resistance of 0.25kA and a short-circuit resistance of 1.5kA. Power losses are only 3.5W at a frequency of 50/60Hz. The IP20 protection degree provides protection against finger contact.
