Parameters: Parameter Value / Description Product Series PowerLogic iPRU (Intelligent Power Relay Unit) Rated Operational Current (Ith) 40 A per pole at 400V AC Number of Poles 4 (can be used for 3P + N or 4 independent SP circuits) Contact Configuration 4 Normally Open (NO) contacts (1 per pole). Control Voltage (Coil Voltage - Uc) Available in multiple standard voltages (e.g., 24V AC/DC, 110-120V AC, 230-240V AC). Must be specified when ordering. Rated Operational Voltage (Ue) Up to 400/415 V AC, 50/60 Hz Rated Thermal Current (Ithe) 40 A Utilization Category AC-1 (Non-inductive or slightly inductive loads) AC-3 (Squirrel cage motor: Starting, Switching off) at a lower current rating (e.g., 15-20A). Switching Capacity Depends on category. For AC-1: Typically 40A. For motor loads (AC-3), refer to derating curves in the catalog. Electrical Life High number of operations (e.g., >100,000 cycles at rated current). Mounting On 35mm symmetrical DIN rail (EN 60715) Connection Screw-clamp terminals for both control circuit and load circuit. Status Indication LED indicator for coil energization. Standards IEC/EN 60947-4-1 (Contactors and motor-starters) & IEC/EN 60947-5-1 (Control circuit devices) Ambient Temperature Typically -25°C to +60°C
