Residual current circuit breaker – RCD LR – 4P – 400 V~ – 63 A – 300 mA – AC type

Product Features:

• High-capacity 4-pole residual current circuit breaker (RCD) from Schneider Electrics LR range, engineered for effective protection against earth leakage faults in 400V~ three-phase electrical systems.
• Rated at 63A with Type AC sensitivity detects sinusoidal alternating residual currents, suitable for general-purpose applications including lighting, socket outlets, and fixed equipment.
• 300mA leakage current sensitivity ideal for fire prevention and equipment protection, commonly used as upstream protection where personal protection is not the primary requirement.
• Supports full disconnection of all active conductors including neutral, ensuring maximum safety and system isolation in the event of a fault.
• DIN rail mountable for fast and secure installation in distribution boards and consumer units.
• Designed for use in TT, TN-S, and TN-C-S earthing systems across residential, commercial, and light industrial environments.
• Equipped with a test button for routine manual safety checks to verify ongoing device functionality.
• Compliant with IEC/EN 61008-1 standards for internationally recognized electrical safety and performance.
