Residual current circuit breaker with overcurrent protection iDPNNVigi-B6-30-AC B 6A 1-pole 30 mA type AC A9D55606

Safety and reliability in one device

The iDPNNVigi-B6-30-AC B 6A 1N residual current circuit breaker with overcurrent protection is a comprehensive solution for protecting electrical installations from the effects of overloads, short circuits and electric shock. The device combines the functions of an overcurrent circuit breaker (B characteristic, 6A) and a residual current circuit breaker (30mA, type AC), providing double protection for both people and equipment. This is particularly important in residential, commercial and industrial buildings where safety is a priority.

Construction and application

This circuit breaker, designed for mounting on a TH35 rail, occupies 2 modules in width. The rated voltage of 230V and frequency of 50Hz make it ideal for standard electrical installations. The ability to disconnect the N pole simultaneously increases functionality and safety. The cross-section of the connectable solid wire is 1…16 mm², and stranded wire 1…10 mm², ensuring compatibility with various types of wires used in electrical installations. The rated short-circuit breaking capacity at 6kA guarantees effective disconnection of the circuit in the event of a short circuit.

Advantages for professionals and end users

• Versatility: Combining the functions of an overcurrent and residual current circuit breaker in one device simplifies installation and reduces the number of components needed.
• Visi-Trip and Visi-Safe indicators: Optical indicators make it easier to identify the cause of tripping (short circuit or leakage current) and confirm correct contact opening, significantly reducing troubleshooting time.
• Functionality testing: The ability to check the correct operation with the "T" control button once a year for the first 7 years of use ensures the device functions correctly for a long time.
• Safety: Protection against unwanted tripping and a high energy limitation class (3) minimize the risk of false alarms and equipment damage.
• Compliance with standards: Meeting the requirements of EN/IEC 60898 and EN/IEC 60947-2 guarantees safety and compliance with applicable regulations.
• Durability: Rated impulse withstand voltage Uimp at 4kV provides resistance to overvoltages.
• Space saving: The compact design (2 modules) allows for efficient use of space in the switchgear cabinet.
• Easy diagnostics: The two-pole lever informs which part of the circuit breaker has operated – overcurrent or residual current – making it easier to locate the problem.
