Differential iID 4P 40A 300mA A

The iID 4P 40A 300mA Type A Residual Current Circuit Breaker, reference A9R24440 from Schneider Electric, is an electrical protection device designed to prevent electric shocks and fire hazards due to earth faults. This 4-pole RCCB is suitable for use in a wide range of residential, commercial, and industrial applications where it is essential to ensure the safety of people and the integrity of electrical installations.

With a rated current of 40A and a sensitivity of 300mA, this RCCB can automatically disconnect the circuit upon detecting a current leakage, effectively protecting against the dangers of electric shocks. Its Type A protection class allows the device to detect both AC and pulsating residual currents, making it an ideal choice for circuits powering electronic devices such as household appliances, lighting, and other DC equipment controlled by frequency converters or inverters.

Main Technical Features:

• Rated Current [In]: 40 A
• Earth Leakage Sensitivity: 300 mA
• Number of Poles: 4P
• Earth Leakage Protection Class: Type A (protects against AC and pulsating currents)
• Rated Operational Voltage [Ue]: 380-415 V AC at 50/60 Hz
• Rated Insulation Voltage [Ui]: 500 V AC
• Operating Frequency: 50/60 Hz

The iID RCCB is equipped with a range of advanced safety features, including the VisiTrip indicator, which facilitates quick identification of the faulty circuit if the device trips, saving time and reducing intervention effort. Additionally, the VisiSafe window provides a clear visual signal on the device's lever, showing a green band when the poles are completely open, allowing safe downstream maintenance tasks.

Safety and Protection:

This RCCB offers effective protection against electric shocks from indirect contact and earth faults, automatically disconnecting the circuit when current leakages exceeding 300mA are detected. This is crucial not only for personal protection but also to prevent fires caused by current leakages in electrical installations. Its rated breaking capacity of 1500 A and its conditional short-circuit current of 10 kA ensure robust protection in case of overloads or short circuits.

Durability and Reliability:

• Mechanical Durability: Up to 20,000 cycles
• Electrical Durability: Up to 15,000 cycles under normal operating conditions
• Surge Resistance: Withstands up to 6 kV, protecting against transient overvoltages caused by lightning or disturbances in the power grid.

Installation:

The iID RCCB is compatible with DIN rail mounting systems, facilitating its integration into modular electrical panels. With a width of 8 modules of 9 mm, this RCCB is designed to occupy minimal space in the panel, allowing for a more compact and organised installation. The terminal connections allow the use of rigid cables up to 35 mm² and flexible cables up to 25 mm², with a recommended tightening torque of 3.5 N.m, ensuring a solid and reliable installation.

Dimensions and Design:

• Height: 91 mm
• Width: 72 mm
• Depth: 73.5 mm
• Weight: 0.37 kg
• Colour: White (RAL 9003)

Additional Benefits:

• VisiTrip: Clearly indicates circuit failure, facilitating identification and reducing diagnosis time.
• VisiSafe: The green band on the lever provides a clear visual signal to ensure the circuit is completely open before performing maintenance work.
• Regulatory Compliance: This device complies with the EN/IEC 61008-1 standard, ensuring high safety and performance standards in electrical installations.

Applications:

The Acti9 iID 4P 40A 300mA Type A RCCB is ideal for any electrical installation where earth leakage protection is necessary, both in residential and industrial environments. Its ability to handle AC and pulsating currents makes it suitable for protecting circuits supplying sensitive electronic equipment.

This Acti9 iID RCCB offers reliable and advanced protection to ensure the safety of electrical installations, while also facilitating maintenance thanks to its visual indicators and easy installation.
