Specifications Parameter Specification Product Range Acti9 iPRU Device Type Residual Current Monitoring Unit (RCMU) / Insulation Monitor Model iPRU 40R4P Number of Poles (Monitoring) 4 Poles (For 3-phase + Neutral systems) Rated Residual Operating Current (IΔn) 40 mA (Main alarm threshold, typically factory-set) Residual Current Type Detection Type A (Detects both AC and pulsating DC residual currents). Adjustable Alarm Thresholds Yes. Typically includes: • Pre-Alarm (PA): Adjustable (e.g., 20mA or 50% of IΔn). • Main Alarm (MA): Fixed or adjustable at 40mA (100% IΔn). Power Supply (Auxiliary Voltage) 24-240V AC/DC (Wide range, specific to this model variant). Consumption Typically < 5VA. Measurement Range 1 to 40mA (continuous monitoring). Accuracy Typically ±5% of measured value. Output Contacts 2 Changeover (CO) Relay Contacts (SPDT): • 1 for Pre-Alarm (PA). • 1 for Main Alarm (MA). Contact Rating Typically 250V AC, 5A resistive. Visual Indicators (LEDs) Power (Green), Pre-Alarm (Yellow), Main Alarm (Red). Required External Sensor Must be used with a dedicated Toroidal Current Transformer (CT). Example: Schneider CSE200N series (size selected based on cable/busbar diameter). Wiring to CT Via a standardized 4-pin connector or terminal block. Mounting DIN Rail Mounting (EN 60715).
