Residual current circuit breaker 3P+N 63A/30mA Type A QuickConnect left N CDS463R

Safety and protection in your electrical installation

3P+N 63A/30mA Type A residual current circuit breaker from the QuickConnect series 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 ground. Its use is essential in every electrical circuit where there is a risk of contact with electricity, both in newly built installations and during the modernization of existing ones.

Functionality and technical parameters

This circuit breaker, catalog number CDS463R, is designed to operate in AC networks with a rated voltage of 400V and a rated current of 63A. Its 3P+N construction (three phase poles and a neutral pole) provides comprehensive protection for the entire circuit. A sensitivity of 30mA guarantees a quick response to dangerous leakage currents, minimizing the risk of injury. Type A designation means that the circuit breaker reacts to sinusoidal alternating currents and pulsating DC currents – which is important when powering modern electronic devices. Mounting is on a DIN rail, which simplifies and speeds up installation.

Construction and installation – convenience for professionals

The circuit breaker is 4 modules wide, allowing for efficient use of space in the distribution board. Screw terminals allow connection of wires with a cross-section from 1 to 25 mm² (solid core) and from 1 to 16 mm² (stranded). This makes the device compatible with various types of wires used in electrical installations. Solid construction and high quality workmanship guarantee reliable operation for a long time. Short-circuit strength at 6kA provides resistance to sudden current surges during short circuits. Additionally, the device meets the EN 61008-1 standard, confirming its compliance with European safety standards. The ambient temperature in operating conditions is from -25 to 40°C, allowing it to be used in various environmental conditions.
