Residual current circuit breaker 63A, 30mA, 4-pole, type A CDA463J

Safety and protection in your electrical installation

Residual Current Device (RCD) 4-pole with a rated current of 63A and a sensitivity of 30mA, type A, is a key element ensuring safety in every electrical circuit. Its task is to quickly disconnect the power in the event of a ground fault current being detected, minimizing the risk of electric shock and equipment damage. It is a reliable protection for you and your devices.

Functionality and application

This RCD is designed for mounting on DIN rails in electrical distribution boards. Thanks to its four poles, it is ideal for protecting three-phase circuits with a neutral conductor. A sensitivity of 30mA ensures a quick response to dangerous leakage currents, and characteristic A guarantees correct operation both for sinusoidal and direct currents – which is particularly important when powering modern electronic devices. Rated voltage of 400V and high short-circuit strength of 6kA make it a universal solution for a wide range of applications – from home installations to commercial facilities.

Installation and diagnostics comfort

This RCD is distinguished not only by its high technical parameters but also by its well-thought-out design that facilitates installation and diagnostics. The possibility of connection using vertical comb busbars provides a quick and safe way to connect to other devices in the distribution board. Two contact position indicators and a residual current release indicator facilitate the identification of the cause of the RCD tripping, which significantly shortens the time of troubleshooting. Additionally, touch protection IP2x and terminal protection covers minimize the risk of accidental electric shock during installation and maintenance. A wide range of accessories allows you to adapt the RCD to the individual needs of each installation. The ability to remove/replace the device without unscrewing neighboring devices (for 10 kA versions) is an additional time saving during servicing.
