Residual current circuit breaker 6kA type AC HNC-25/2/003 194690

Safety and reliability in your electrical installation

This two-pole residual current circuit breaker (RCCB) Eaton HNC-25/2/003 is a key element in protecting electrical installations in residential and commercial buildings. It provides protection against electric shock, and also minimizes the risk of equipment damage and fires. Designed to operate at 230V, it offers a rated current of 25A and a sensitivity to AC residual currents of 0.03A. Its short-circuit strength of 6kA guarantees reliable operation even in the event of overloads.

Functionality and installation

The circuit breaker is designed for easy mounting on a DIN rail (TH-35). Thanks to the dual terminals (lift and rail) at the top and bottom, connecting the wires is simple and convenient, and the wire cross-section can range from 1.5 mm² to 35 mm². The locking mechanism prevents accidental switching on of the circuit breaker after it has been switched off, which increases safety during maintenance work. Additionally, the possibility of later adding auxiliary contacts expands the functionality of the device, allowing for remote signaling of operation.

Practical benefits for installers and users

• Versatility: Type AC circuit breaker effectively protects against alternating current electric shock, making it an ideal solution for standard electrical installations.
• Durability: Rated short-circuit capacity of 6kA ensures reliable operation in harsh operating conditions.
• Easy installation: Quick and easy mounting on a DIN rail saves time during installation.
• Safety: The lock prevents accidental switching on of the circuit breaker during service work.
• Testing: The requirement to test every 6 months ensures continuous device efficiency – this is important for maintaining full protection.
• Compatibility: The ability to expand with additional accessories (auxiliary contacts) increases the functionality of the circuit breaker.
• Wide range of wire cross-sections: Support for wires with a cross-section from 1.5 mm² to 35 mm² provides flexibility when choosing the appropriate cables.
• Resistance to external conditions: Operation at temperatures from -25°C to 55°C and IP20 protection rating guarantee reliability in various environmental conditions.

This residual current circuit breaker is not only a protective element, but also an investment in the safety and peace of mind of users and the comfort of installers. It is a solid and reliable device that will meet the expectations of even the most demanding customers.
