P1RD4P63A030 - Lovato - Residual current device

<h3>Residual current protection for modular panels</h3><p>This residual current device protects modular electrical circuits by detecting leakage current and disconnecting the affected line according to the device function. It is used in machine panels, distribution boards and auxiliary circuits where protection against earth-fault conditions must be coordinated with overcurrent protection when present.</p><h4>Residual current and circuit data</h4><p>device type residual current circuit breaker; rated current 63 A; rated residual current 30 mA; residual current type A; poles 4. Selection must follow rated current, residual current value, device type and pole configuration. RCBO versions combine residual-current and overcurrent functions, while residual current blocks and circuit breakers must be matched with the protected feeder and the installation wiring scheme.</p><h4>Testing and maintenance</h4><p>During commissioning, identify the protected circuit, verify terminal assignment and check the trip function according to the panel procedure. For replacement, compare rated current, residual current, type, pole arrangement and curve or breaking capacity where present, then repeat functional and continuity checks.</p><p>Clear marking helps distinguish residual-current circuits with different sensitivity or type. This is important when several devices protect adjacent feeders in the same panel row.</p><p>The panel record should show which loads are downstream of each residual-current device and whether the device also includes overcurrent protection. During troubleshooting, this avoids confusing an earth-fault trip with an overload trip and keeps replacement choices tied to the actual feeder.</p><p>This approach keeps protection selective, simplifies periodic checks and reduces wiring mistakes when the panel is expanded or a feeder is modified.</p> <h3>Residual current protection for modular panels</h3><p>This residual current device protects modular electrical circuits by detecting leakage current and disconnecting the affected line according to the device function.
