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
