Residual current circuit breaker with overcurrent protection DPNVigiK-B20-30-AC B 20A 1-pole 30 mA type AC A9D22620

Residual Current Circuit Breaker – Safety and Reliability in One Device

This single-pole residual current circuit breaker with overcurrent protection, model DPNVigiK-B20-30-AC, is a key element in protecting the electrical installation. It provides protection against the effects of short circuits, overloads, and electric shock. It is a device from the Acti 9 series by Schneider Electric, known for its high quality and innovative solutions.

Functionality and Application

The circuit breaker combines the functions of an overcurrent circuit breaker (B characteristic) and a residual current device (30 mA, type AC). This means that it not only protects against overload and short circuit but also detects leakage currents to earth, minimizing the risk of electric shock. It is designed for use in circuits with a voltage of 240 V and a rated current of 20 A. Thanks to its compact dimensions (2 module width), it is ideal for use in switchboards with limited space.

• Personal protection: Detection of leakage currents to earth protects users from electric shock.
• Installation protection: Protection against overload and short circuit prevents damage to wires and devices.
• Fast reaction: B characteristic ensures quick tripping in the event of a short circuit, minimizing the duration of the hazard.
• Status indicators: VisiTrip (tripping) and VisiSafe (contact opening) optical indicators make it easier to diagnose problems with the installation.
• Functionality testing: The ability to perform a functionality test with the control button "T" (once a year for the first 7 years of use) ensures the correct operation of the device.
• Compatibility: The device is compatible with all commercially available busbars, making installation and replacement easier.

Construction and Technical Parameters

The circuit breaker is made of high-quality plastic, which ensures its durability and resistance to mechanical damage. It has a protection degree of IP20, which means protection against contact with fingers and solid objects with a diameter of more than 12.5 mm. The rated short-circuit breaking capacity is 6 kA, which guarantees effective disconnection of the circuit in the event of a short circuit. A mechanical lock prevents accidental opening of the circuit breaker during operation. The cross-section of the connected multi-wire cable is 1…16 mm², and the single-wire cable is 1…25 mm². The ambient temperature in operating conditions is in the range of -5…40°C.
