Residual current circuit breaker 3P+N 63A 30mA 10kA Type A CDA663J

Safety and protection in your electrical installation

Residual Current Device (RCD) 3P+N with a rated current of 63A and a sensitivity of 30mA is a key element ensuring the safety of using the electrical installation. The device effectively protects against electric shock by detecting even small leakage currents to earth. Its 3P+N design (three phases and neutral) makes it ideal for securing circuits in residential, commercial and industrial buildings.

Functionality and technical parameters

The circuit breaker is characterized by a high short-circuit breaking capacity of 10kA, which guarantees its reliable operation even in the event of serious disturbances in the network. The use of characteristic A provides a quick response to leakage currents, minimizing the risk of injury. Mounting is on a DIN rail, which facilitates integration with the existing distribution board. Adapted to work in a wide temperature range (from -25°C to 70°C) and with a degree of protection of IP20, it can be used in various environmental conditions. The circuit breaker has a lock to prevent accidental disconnection.

For the installer and end user

This residual current device is not only a protective element, but also an investment in comfort and peace of mind. For the installer, it means easy mounting on a standard DIN rail and confidence in the reliable operation of a device that meets safety standards. The end user, in turn, gains a guarantee of protection against electric shock and equipment damage, as well as the ability to safely use electrical energy in their home or company. The device width of 4 modules allows for optimal use of space in the distribution board. The possibility of using wires with a cross-section from 1 mm² to 25 mm² (solid) or from 1 mm² to 16 mm² (stranded) provides flexibility during installation.
