Residual current circuit breaker 6kA type AC HNC-40/4/003 194694

Safety and reliability in your electrical installation

This four-pole residual current circuit breaker from Eaton's xPole Home series is a key element ensuring protection against electric shock and overloads in your home or business. The device, catalog number 194694 (HNC-40/4/003), combines proven technology and modern solutions, guaranteeing safety and long-term reliability.

The circuit breaker is designed for use in three-phase installations, offering effective protection for both users and electrical devices. Its function is to quickly disconnect the power supply in the event of a leakage current, minimizing the risk of electric shock and potential damage.

Key features and application

The HNC-40/4/003 circuit breaker is characterized by a rated current of 40A and a sensitivity to AC type differential currents (30mA), meaning it reacts to sinusoidal leakage currents. The rated breaking capacity is as high as 6kA, ensuring safe disconnection of the circuit in the event of a short circuit. Mounting is done on a standard DIN TH-35 rail, and the compact dimensions (4 modules wide) make it easy to integrate with an existing distribution board.

Why choose this circuit breaker?

• Versatility: Ideal for use in residential and commercial buildings.
• Safety: Effective protection against electric shock and damage to the installation.
• Easy installation: Standard mounting on a DIN TH-35 rail simplifies installation and replacement.
• Double terminals: Both screw and busbar terminals allow for flexible connection of wires.
• Compliance with standards: The product meets strict safety and quality standards.
• CFI6 replacement: Seamless replacement of older Eaton residual current circuit breaker models.

Technical specifications – what you should know?

The HNC-40/4/003 circuit breaker has been designed with durability and reliability in mind. It has a protection rating of IP20, which provides protection against finger contact and protects against external factors. It is adapted to work in an ambient temperature from -25°C to +60°C. Additionally, it has a lock preventing accidental switching on or off of the device. The possibility of mounting additional equipment (auxiliary contacts) expands the functionality of the circuit breaker, enabling remote signaling of operation or integration with home automation systems. The short-circuit withstand strength (Icw) is 6kA, and the surge current resistance is 0.25kA. The cross-section of the multi-wire connecting cable is 1.5 - 16 mm², and the single-wire cable is 1.5 - 35 mm².

Remember to test the residual current circuit breaker regularly (recommended every 6 months) to ensure its proper operation and provide continuous protection for your electrical installation!
