Residual current circuit breaker with overcurrent protection iDPNNVigi-B25-30-AC B 25A 1-pole 30 mA type AC A9D55625

Residual Current Breaker with Overcurrent protection iDPNNVigi-B25-30-AC B 25A is a reliable protection for electrical installations, combining the functions of an overcurrent and residual current circuit breaker. The device is designed to protect circuits against overload, short circuit and electric shock. A rated residual current of 30 mA provides effective protection for people.

Features and application

This circuit breaker, with characteristic B, is ideal for use in home installations and public buildings. Characteristic B means that the circuit breaker reacts quickly to an increase in short-circuit current, but is more tolerant to short-term current surges, which is important when connecting devices with electric motors or other loads with high starting current. The breaking capacity of 6 kA guarantees safe disconnection of the circuit in the event of a failure. Compact dimensions (2 module width) allow for easy mounting in a distribution board.

Advantages and benefits

• Versatility: Combining the functions of an overcurrent and residual current circuit breaker in one device simplifies installation and reduces costs.

• High reliability: Compliance with EN/IEC 60898 and EN/IEC 60947-2 standards ensures reliable operation in various working conditions.

• Fast fault identification: Visi-Trip (electrical release) and Visi-Safe (contact opening) optical indicators make it easy to locate a faulty circuit – even without having to open the distribution board.

• Safety: The ability to check the correct operation with the "T" test button once a year for the first 7 years of use increases the certainty of the device's operation.

• Comfort of installation: Cross-section of the connectable solid conductor up to 16 mm² and stranded conductor up to 10 mm² provides flexibility in cable selection.

• Protection against manipulation: The possibility of using a padlock increases security and protects against unauthorized disconnection of the circuit breaker.

• Durable construction: Energy limitation class 3 and impulse withstand voltage 0.25 kA ensure long-lasting and trouble-free operation of the device.

Construction and parameters
