Residual current circuit breaker 6kA type A HNC-25/4/003-A 194687

Safety and protection in electrical installations

The HNC-25/4/003-A residual current circuit breaker (RCCB) is a key element ensuring safety in electrical installations, both in residential and industrial buildings. The device is designed to protect against electric shock, operating when a leakage current to ground is detected. Its task is to quickly disconnect the power supply, minimizing the risk of injury and equipment damage.

This four-pole circuit breaker with a rated current of 25A and a sensitivity of 30mA (type A) effectively responds to sinusoidal and pulsating currents, making it a universal solution for various applications. The short-circuit breaking capacity of 6kA guarantees reliable operation even in the event of overloads or short circuits.

Installation and application

The HNC-25/4/003-A circuit breaker is mounted on a DIN rail, which facilitates its installation and integration with existing switchgear. The cross-section of the connected multi-wire cable up to 16mm² and single-wire cable up to 35mm² provides flexibility in connecting different types of cables. With a width of 4 modules, the device is compact and does not take up much space in the distribution board.

The use of a residual current circuit breaker is mandatory in many electrical installations, especially where there is a risk of electric shock. This is particularly important in wet rooms (bathrooms, kitchens) and in places with an increased risk of contact with grounded structural elements.

Characteristic features and benefits

• High reliability: Rated breaking capacity of 6kA and impact current resistance of 0.25kA ensure effective protection of the installation against the effects of short circuits and overloads.
• Wide range of applications: Type A sensitivity allows protection against pulsating currents, which is important when powering electronic devices.
• Easy installation: DIN rail mounting and double terminals (screw/busbar) facilitate and speed up installation.
• Safety of use: A lock prevents accidental switching on of the circuit breaker after it has been switched off by the protection device.
• Durable construction: Made of high-quality materials ensures long-lasting and trouble-free operation of the device at temperatures from -25°C to +55°C.
• Compliance with standards: Meets the requirements of applicable safety standards, ensuring compliance with building regulations.
• Testing: Recommended testing every 6 months ensures continuous efficiency of the device and effectiveness of protection.
• Expandability: Compatible with additional Eaton xPole Home accessories, such as auxiliary contacts or padlock.
• Status indicator: A clear contact position indicator (red/green) informs about the current status of the device – on/off.

Thanks to these features, the HNC-25/4/003-A residual current circuit breaker is a comprehensive solution for ensuring safety and reliability of the electrical installation for both professional installers and end users.
