Specifications: Parameter Specification Product Range TeSys Island Device Type Electronic Overload Relay (Direct Mounting) Rated Operational Current (Iu) 85 A (Setting range: 0.4 - 1.0 x Iu, i.e., 34 A to 85 A). Motor Power Range (Reference) ~ 40 kW / 55 HP (at 400V AC) Protection Functions • Thermal Overload Protection (Class 10A trip curve) • Phase Unbalance / Loss Detection • Jam Protection (Short-circuit or locked rotor) • Ground Fault Protection (Optional, via external sensor and module) • Undercurrent Protection (Optional) Current Sensing Internal Current Transformers (CTs) - Direct connection to main power (no external sensors needed for basic functions). Rated Insulation Voltage (Ui) 690 V AC Power Supply 24V DC (Supplied via the connected TeSys Island communication base). Auxiliary Contacts 1 NO (Normally Open) + 1 NC (Normally Closed) fault signaling contacts (rated for control circuits). Mounting Direct mounting onto a compatible TeSys Island contactor or disconnect block (e.g., ILS1C, ILS1D series) to form a complete motor starter. Communication Interface Requires a TeSys Island Communication Base (e.g., ILB1BL series). Enables protocols: EtherNet/IP, Modbus TCP, PROFINET. Local Interface (LCI) Graphical display, navigation push buttons, LED indicators for Power, Run, Fault, Communication. Allows for local parameter setting and real-time current/temperature display. Standards & Approvals UL 508, CSA C22.2 No. 14, IEC/EN 60947-4-1, IEC/EN 60947-5-1, CE, RoHS.
