Residual current device with overcurrent protection iDPNNVigi-C16-30-SI C 16A 1P 30 mA type SI A9D33616

Advanced electrical installation protection in a compact form

The Schneider Electric iDPN N Vigi type A-SI residual current circuit breaker with overcurrent protection is a professional solution combining the functions of an MCB and an RCCB in a single modular unit.

Design and safety technologies

The device features a two-pole design with one protected phase pole and simultaneous disconnection of the neutral conductor. A width of 2 modules (36mm) allows for mounting on a standard DIN rail, and a mounting depth of 44mm enables installation even in shallow distribution boards.

The type A-SI (Super Immunized) technology reacts more slowly to short-term current surges, making it well-suited for starting motor-driven devices and handling transient leakage currents occurring during the normal operation of certain electrical appliances.

Operating parameters and technical characteristics

The breaker operates at a rated voltage of 230V AC with a frequency of 50Hz. It features a rated current of 16A and a C tripping characteristic, which provides a delayed response to short-term inrush currents from electric motors.

A differential sensitivity of 30mA allows it to respond to sinusoidal and pulsating DC residual currents, protecting against electric shock while maintaining high immunity to nuisance tripping. A rated breaking capacity of 6kA allows it to safely interrupt even significant short-circuit currents.

Signaling and diagnostic systems

The innovative Visi-Trip system utilizes a two-part lever to indicate the type of trip - mechanical or differential. A white-red optical indicator shows which part of the breaker has tripped.

Additionally, the Visi-Safe system uses a green indicator to confirm the opening of the breaker contacts, providing certainty regarding the insulation status of the protected circuit during service work.

Operational safety and maintenance

The device is equipped with a "T" test button, which enables periodic checks of the differential mechanism's correct operation. According to the manufacturer's recommendations, testing should be performed once a year for the first 7 years of operation.

The IP20 protection rating allows for safe mounting inside distribution boards, while in combination with a modular enclosure, it achieves an IP40 rating, meeting the requirements of standards for domestic and industrial installations.

Operating conditions and compatibility

The breaker maintains full functionality across a wide ambient temperature range from -25°C to +60°C, enabling its use in both unheated rooms and industrial environments with elevated temperatures.

The cross-sections of the connected conductors range from 1mm² to 16mm² for solid conductors and from 1mm² to 10mm² for stranded conductors, ensuring connection versatility in various types of installations.

Regulatory compliance and certificates

The product meets the requirements of international IEC/EN 61009 standards and national standards regarding residual current devices with overcurrent release. It holds VDE certification, confirming the highest standards of quality and operational safety.

An energy limiting class of 3 and an overvoltage category of III allow for optimal energy characteristics during switching processes, minimizing the impact on other devices in the electrical installation.
