Tips

• Mandatory Upstream Overcurrent Protection: It is absolutely critical to understand that the Schneider Earth Leakage ACTI9 IID 2P 63A 30mA (A9R41263) is an earth leakage protection device only and does not provide overcurrent (overload or short-circuit) protection. A suitably rated Miniature Circuit Breaker (MCB) or fuse must be installed upstream to protect the RCCB itself and the entire circuit from overloads and short circuits. The datasheet explicitly states a "Rated conditional short-circuit current" of 10 kA, indicating the necessary coordination with an upstream MCB.
• Regular Functional Testing is Crucial: Always perform the integrated test button operation periodically, as recommended by relevant safety standards (e.g., monthly). This is vital to verify the mechanical and electrical integrity of the RCCB's tripping mechanism.
  • Testing Procedure: Ensure the RCCB is in the ON position and the circuit is energized. Press the 'T' (Test) button located on the front of the device. The RCCB should trip immediately (move to the OFF position). If it fails to trip, this indicates either a lack of supply to the RCCB or a faulty device, which requires immediate inspection and potential replacement by a qualified electrician.
  • Safety Caution: The test button is solely for functional verification; never use it to switch off the RCCB for isolation purposes or to disconnect the circuit for maintenance.
• Professional Installation is Paramount: All electrical installation, wiring, and commissioning involving the Schneider Earth Leakage ACTI9 IID 2P 63A 30mA (A9R41263) must be executed by a qualified and licensed electrician. Strict adherence to all local electrical codes, national wiring regulations (e.g., SANS 10142-1), and safety guidelines is non-negotiable to ensure the safe, compliant, and proper operation of the electrical system. HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH: Isolate, lock off and label the power sources before and during the installation and maintenance. Failure to follow these instructions will result in death or serious injury.
• Correct Wiring and Torquing: Ensure that both the live and neutral conductors are correctly connected to the device, as specified in the installation instructions. Incorrect wiring can prevent the RCCB from functioning properly. Pay meticulous attention to the wire stripping length (14mm) and the recommended tightening torque (3.5 N.m) for the terminals. Use a calibrated torque screwdriver to achieve the correct torque, preventing loose connections, increased resistance, overheating, and potential fire hazards. The provided installation image clearly illustrates the correct wire insertion method (smiley face) versus incorrect methods (sad faces).
• Adequate Environmental Enclosure: The Schneider Earth Leakage ACTI9 IID 2P 63A 30mA (A9R41263) has an IP20 degree of protection, meaning it is protected against solid objects larger than 12.5 mm but offers no inherent protection against water. It must be installed inside a suitable electrical enclosure (e.g., a distribution board with an IP40 or higher rating) to protect it from moisture, excessive dust, and other environmental contaminants relevant to its operating location.
• Optimal Storage Conditions: Before installation, store the RCCBs in a dry, clean environment that adheres to the specified ambient temperature range (-40°C to 85°C). Avoid prolonged exposure to extreme humidity, corrosive atmospheres, or direct sunlight to preserve the product's integrity and long-term performance.
• Responsible End-of-Life Management: At the end of its operational life, the Schneider Earth Leakage ACTI9 IID 2P 63A 30mA (A9R41263) must be disposed of responsibly in accordance with Waste Electrical and Electronic Equipment (WEEE) directives and all local environmental regulations. Do not discard it with general waste; instead, utilize designated electronic waste recycling and disposal channels.
