Residual Current Device (RCD) iID-40-2-300-AC 40A 2-pole 300mA type AC A9Z14240

Protection and safety in your electrical installation

The iID-40-2-300-AC residual current circuit breaker is a key element ensuring safety in electrical installations. The device, designed by Schneider Electric, protects against electric shock, prevents fires, and protects devices from damage caused by short circuits and overloads. Its operation is based on detecting leakage currents, which may indicate damage to insulation or other irregularities in the circuit. The breaker's quick reaction minimizes the risk of dangerous situations.

Construction and application

The two-pole breaker with a rated current of 40A and a sensitivity of 300mA of type AC is designed to protect electrical circuits in residential, commercial buildings and in industry. Type AC means that the device effectively detects alternating leakage currents – most commonly found in standard installations. The construction with double terminals allows connection of wires with different cross-sections, which facilitates installation and adaptation to existing installations. A width of 2 modules allows for efficient use of space in the distribution board.

Functionality and characteristic features

The iID-40-2-300-AC breaker stands out with a number of features that translate into ease of use and reliable operation:

• High short-circuit strength (10 kA) – ensures resistance to sudden current surges during short circuits.
• Optical trip indication (Visi-Trip) – facilitates quick identification of the cause of the circuit disconnection.
• Possibility of removal without removing the busbar – simplifies maintenance and service work.
• Removal from the DIN rail without tools – speeds up the installation and removal of the device.
• Test button "T" – allows regular checking of the breaker's functionality (once a year for the first 7 years of use).
• Convenience for installers: placement of the neutral conductor (N) on the left side facilitates alignment with overcurrent breakers.
• Wide range of wire cross-sections: possibility to connect single-wire conductors with a cross-section of 1…35 mm² and multi-wire 1…25 mm².
• Compliance with IEC EN 61008-1 standard - guarantee of meeting European safety standards.

Thanks to these features, the breaker is a reliable solution for both professional installers and end-users looking for effective protection for their electrical installations. Its solid construction and advanced functions ensure long-lasting and safe operation.
