Residual current circuit breaker 6kA type A HNC-63/4/003-A 194689

Safety and reliability in your electrical installation

The Eaton HNC-63/4/003-A residual current circuit breaker (RCCB) is a key element in protecting electrical installations in residential and commercial buildings. It provides protection against electric shock, fire and equipment damage by reacting to abnormalities in the circuit. This four-pole circuit breaker with a rated current of 63A and type A sensitivity effectively protects against both sinusoidal and pulsating DC leakage currents up to 6mA.

Design and installation – comfort for the installer and user

The circuit breaker is designed for easy mounting on a DIN rail, which significantly speeds up the installation process. Double terminals (lift and screw) located at the top and bottom of the housing provide flexibility in connecting wires with a cross-section from 1.5 mm² to 35 mm² (solid) or 1.5 mm² to 16 mm² (stranded). The locking mechanism prevents accidental switching on of the circuit breaker after it has been switched off due to a fault. Additionally, the possibility of later adding an auxiliary contact allows for signaling the device's operation.

Protection tailored to your needs

The HNC-63/4/003-A RCCB is characterized by a high breaking capacity of 6 kA, which guarantees effective protection even in the event of high short-circuit currents. It meets safety standards, and its housing with an IP20 degree of protection provides protection against contact. It is important to test the circuit breaker regularly (recommended every 6 months) to ensure its proper operation. This ensures that the electrical installation is always safe and ready for use.

Additional features:

• Versatility: Can be used in three-phase installations.
• Durability: Mechanical endurance of up to 20,000 switching operations ensures long-lasting and reliable operation.
• Compatibility: Integration with additional Eaton xPole Home accessories, such as auxiliary contacts or surge protectors.
• Signaling: Contact position indicator (red/green) informs about the current status of the device.
• Operating temperature: Wide range of ambient temperatures (-25°C to 60°C) allows installation in various environmental conditions.
• Compliance with standards: Ensures compliance with applicable electrical safety regulations.
