IPRU 40R4P

The Schneider Electric iPRU 40R4P is an iPRU Residual Current Monitoring Module. It is not a protective device (like an MCB or RCD), but an electronic monitoring and signalling module designed to detect and indicate earth leakage currents in real-time.

Specifications Parameter Specification Product Range Acti9 iPRU Device Type Residual Current Monitoring & Signalling Unit Model iPRU 40R4P Number of Poles (for wiring) 4-Pole (for 3-phase + Neutral systems) Rated Residual Operating Current (IΔn) 40 mA (This is its sensitivity/measurement range) Residual Current Type Type A (Can detect both AC and pulsating DC residual currents). Power Supply Voltage Typically 24V AC/DC or 110-230V AC/DC (depending on version). Must be specified. Measurement Range Typically 1mA to 40mA. Alarm Thresholds Adjustable (e.g., Pre-alarm at 50% IΔn, Alarm at 100% IΔn). Output Contacts 2 Changeover (CO) Relay Contacts (NO/NC) for pre-alarm and main alarm signalling. Contact Rating Typically 250V AC, 5A resistive. Accuracy Typically ±5% of reading. Housing / Mounting Modular DIN-rail mounted device (e.g., 4 modules wide). Required External Sensor Must be used with a compatible toroidal current transformer (e.g., Schneider CSE200N or similar). The sensor size depends on the cable/busbar diameter. Standards IEC/EN 62020, IEC/EN 60947-1
