Residual current circuit breaker 63A, 30mA, 2-pole, type A CDA263J

### Safety and reliable installation protection

Residual Current Device (RCD) 63A, 30mA, 2-pole, type A is a key element ensuring safety in every electrical installation. This device effectively protects against electric shock by reacting to leakage currents and disconnecting the circuit when a hazard is detected. This is particularly important in rooms with increased humidity, such as bathrooms or kitchens, but also in places exposed to contact with water.

Functionality and technical parameters

This RCD is characterized by a rated current of 63A and a sensitivity of 30mA, making it an ideal solution for protecting circuits with higher power consumption. Type A execution means that it is designed to detect both sinusoidal alternating currents and pulsating DC currents – often found in modern electronic devices. Mounting is done on a standard DIN rail, occupying 2 modules in width. The rated insulation voltage Ui is 500V, and the short-circuit strength (Icw) is 6kA, which guarantees reliable operation even in the event of overloads or short circuits.

Installation and diagnostics comfort

The design of the RCD has been carefully thought out in terms of easy installation and diagnostics. It has two-sided screw terminals allowing the connection of wires with a cross-section from 1 to 25 mm² (solid) and from 1 to 16 mm² (stranded). This makes the installation quick and convenient. Additionally, the presence of two indicators – contact position and residual current release – facilitates the identification of the cause of the RCD operation, which is extremely helpful when diagnosing failures. The width expressed in number of modules is 2, which allows for optimal use of space in the distribution board.

Application and compliance with standards

The CDA263J residual current device is used in electrical installations of residential, commercial and industrial buildings. It is compatible with vertical and horizontal comb busbars from Hager, which facilitates the creation of comprehensive security systems. The device meets all applicable safety standards and has appropriate quality certificates. The ambient temperature in operating conditions is from -25 to 40°C, which ensures its reliable operation even in difficult atmospheric conditions.
