Combined circuit breaker iCV40N-C20-30-AC C 20A 3-pole 30 mA type AC A9DE3720

Acti9 family RCBO combination switch

/br>The iCV40N-C20-30-AC combination switch is an advanced RCBO (Residual Current Breaker with Overcurrent protection) device from the Schneider Electric Acti9 family. This compact solution combines the functions of an overcurrent circuit breaker and a residual current device in a single housing. /br>#### Design and technical parameters /br>The device is designed as a 3P+N-pole switch with three protected phase poles and a separate neutral pole. It features a rated current of 20A and a C tripping characteristic. The breaking capacity is 6kA according to the EN/IEC 61009-1 standard, which guarantees effective interruption even of high fault currents. /br>The width of the device is 5 modules (approximately 90mm), allowing for economical space management in the distribution board. The mounting depth is 44mm, and the total dimensions are approximately 90×93×73mm. The switch weighs approximately 500g and is designed for mounting on a standard DIN rail. /br>#### Residual current and overcurrent protection /br>The AC type residual current protection with 30mA sensitivity protects against electric shock from indirect contact and against fire hazards resulting from current leakage. The operation is instantaneous, minimizing the duration of the hazardous situation. /br>The overcurrent circuit breaker protects conductors against overload and short circuits. /br>#### Operating and environmental parameters /br>The device operates in a temperature range from -5°C to +60°C, enabling installation in most building distribution boards. The operating frequency is 50/60Hz, and the rated voltage is 400V. The insulation voltage Ui is 440V, and the impulse withstand voltage Uimp is 4kV. /br>The protection rating is IP20 (IP40 after installation in a distribution board). The energy limiting class is 3, indicating good short-circuit energy limiting properties. /br>#### Service and operational functionality /br>Two unique VisiTrip indicators significantly facilitate servicing - they indicate the faulty circuit and the type of fault, which reduces the time required to locate the problem. The device features the possibility of mechanical locking and sealing, which increases operational safety. /br>Mechanical and electrical endurance is 20 000 cycles. Simultaneous disconnection of the neutral conductor ensures full circuit separation during tripping. /br>#### Connections and compatibility /br>The switch is equipped with tunnel terminals allowing for the connection of single-core wires with a cross-section from 1 to 16 mm² and multi-core wires with a cross-section from 1 to 10 mm². The tightening torque for connections is 2 Nm. /br>The device is compatible with standard busbars and Schneider Electric distribution blocks. The mounting pitch between phases is a standard 18mm, and between phase and neutral is 9mm. /br>#### Normative compliance and safety /br>The switch meets the requirements of European standards EN/IEC 61009 and EN/IEC 60947-2, holding EAC and IMQ certificates. Overvoltage category III and pollution degree 3 make it suitable for most building applications.
