Residual current circuit breaker with overcurrent protection iDPNNVigi-C40-30-AC C 40A 1-pole 30 mA type AC A9D31640

Safety and Reliability in Your Electrical Installation

This residual current circuit breaker with overcurrent protection is a key element in protecting electrical installations, both in residential and commercial buildings. Model iDPNNVigi-C40-30-AC C 40A 1N, with catalog number A9D31640, combines protection against short circuits, overloads, and electric shock. This device provides comprehensive protection for electrical circuits, minimizing the risk of failure and ensuring user safety.

Construction and Operating Principle

This circuit breaker is a single-pole (1P+N) device designed for mounting on a DIN rail. Its C characteristic means it is designed to protect circuits with inductive loads, such as motors or transformers – it copes well with short-term current surges during the start-up of these devices. The rated differential current of 30 mA ensures a quick response in the event of a current leakage to earth, minimizing the risk of electric shock. Additionally, the presence of Visi-Trip (white-red) and Visi-Safe (green) indicators makes it easy to identify the cause of the disconnection and confirm the open state of the contacts. The ability to perform a functionality test once a year for the first 7 years of use allows for regular control of the device's functionality.

Key Features and Benefits

• Multi-level protection: Protection against overload, short circuit and electric shock in one device.
• C characteristic: Ideal for circuits with motors and other inductive loads – allows for temporary overloads without unnecessary tripping.
• High breaking capacity: 6 kA guarantees effective disconnection of the circuit in the event of a short circuit.
• Status indicators: Quick identification of the cause of disconnection thanks to the Visi-Trip and Visi-Safe indicators.
• Wide range of applications: Suitable for installations in residential, commercial and industrial buildings.
• DIN rail mounting: Enables easy and quick installation in the distribution board.
• Wire cross-section: Accepts solid wires with a cross-section of 1…16 mm² and stranded wires 1…10 mm².
• Safety confirmed by standards: Compliance with EN/IEC 61009 standards ensures a high level of safety and reliability.

Technical Specification for Professionals

The circuit breaker is characterized by a rated voltage of 230 V AC and a rated current of 40 A. It has an energy limitation class of 3 and a surge category of III, making it suitable for use in various environmental conditions. The IP20 degree of protection provides protection against finger contact, and the ambient operating temperature is from -5°C to 60°C. The rated impulse withstand voltage is 4 kV, guaranteeing resistance to transient overvoltages. The two-pole design (1P+N) provides complete protection of the neutral conductor.
