Schneider RCCB 4P 63A 30mA

Description

Product DescriptionThe Acti9 xID is an industrial-grade residual current device (RCD) designed for three-phase plus neutral electrical systems. It continuously monitors the balance of electrical current flowing through all three phases and the neutral line. If it detects a microscopic imbalance—meaning current is leaking somewhere it shouldn’t be (like through a human body into the ground)—it cuts off all power instantly.Key Features4-Pole (4P) Configuration: Monitors three live phase wires and the neutral line simultaneously, making it essential for complex three-phase distribution networks.63A Current Rating: Serves as a high-capacity master safety switch, capable of handling a continuous incoming load up to 63 Amps.30mA High-Sensitivity Trip: Engineered to trip if an earth leakage current as tiny as $30mA$ is detected. This is the global safety standard required for human life protection, as $30mA$ is the threshold before electrical current can cause cardiac arrest.Manual Test Button: Features a prominent “T” button on the front face. Pressing this manually simulates an earth fault, allowing users to test the internal mechanical tripping mechanism regularly.DIN Rail Mount: Easily snaps onto standard 35mm wide DIN rails inside power panel enclosures.Compatible Mechanisms and SystemsAn RCCB is always paired directly with upstream and downstream panel devices to create a fully protected electrical system:1. In-Panel Component CompatibilityUpstream Short-Circuit Protection: An RCCB does not protect against overloads or short circuits. Therefore, it must be paired with an upstream Molded Case Circuit Breaker (MCCB) or a Miniature Circuit Breaker (MCB) (like a 63A master fuse/MCB) to shield it from explosive overcurrents.Downstream Branch MCBs: It acts as the “mother” safety switch, feeding power into a row of single-pole or three-pole MCBs via comb busbars to protect individual room or machine circuits.Distribution Boards: Fits seamlessly inside universal three-phase TPN (Thermoplastic/Metal) distribution boards.2. Mechanisms and Environments It Safe-KeepsBecause a 30mA RCCB is designed to prevent human electrocution, it is installed inline with mechanisms where humans frequently interact with electricity or damp environments:Industrial Workshop Machining Power: Protects three-phase outlets powering handheld tools, heavy lathes, welding stations, and cutting machines where wire insulation could get compromised.Commercial Kitchen Systems: Safeguards high-powered industrial dishwashers, walk-in chillers, and electric ovens where liquid exposure increases the risk of earth faults.Water Pump Systems: Essential for three-phase submersible water pumps, pool filtration machinery, and sewage pumps where electricity directly interfaces with water infrastructure.Whole-House Single/Three-Phase Mains: Acts as the primary incoming trip switch for residential properties to protect family members from faulty home appliances or damaged wall sockets.
