LEGRAND Residual current circuit breaker – RCD LR – 400 V~ – 63 A – 100 mA – AC type

Product Features:

• High-performance 4-pole residual current device (RCD) from Schneider Electrics LR series, designed to detect earth leakage currents and provide enhanced protection in three-phase systems.
• Rated at 63A with Type AC sensitivity suitable for detecting sinusoidal alternating residual currents in general-purpose circuits such as lighting, HVAC, and industrial equipment.
• 100mA leakage current sensitivity helps prevent fire hazards and protects equipment, making it ideal for use as upstream protection where personal protection is not the primary concern.
• Supports 400V~ three-phase networks, ensuring full disconnection of all live conductors including neutral in the event of a fault for maximum safety.
• Designed for TT, TN-S, and TN-C-S earthing systems where reliable residual current protection is essential.
• DIN rail mountable for quick and efficient installation in consumer units or electrical panels.
• Equipped with a test button for regular manual checks to verify ongoing safety and performance.
• Complies with IEC/EN 61008-1 standards, ensuring long-term reliability, safety, and compliance with international regulations.
