Key Parameters Category Description / Value Product Line Eaton DILM Model / Frame Size DILM300A Rated Operational Current (Iₑ) at AC-3 300 A (For squirrel-cage motors: Starting, switching off during running) Rated Operational Power at AC-3 ~ 160 kW / 220 HP at 400V 50Hz Rated Operational Voltage (Uₑ) Up to 1000 V AC, 50/60 Hz Rated Thermal Current (Iᵼₕ) 410 A Poles 3 (Main Contacts) Coil Control Voltage Standard factory setting is often 400V AC, 50/60Hz. However, this is a configurable parameter. The coil is available in a wide range of AC and DC voltages (e.g., 24V, 110V, 230V, 400V, 500V). The exact voltage must be confirmed by the order code sticker on the device itself. Utilization Categories AC-3: Squirrel-cage motors (starting, switching off during running) AC-1: Non-inductive or slightly inductive loads Electrical Durability Hundreds of thousands of operations (dependent on load) Mechanical Durability Millions of operations Arc Extinction System Sintered metal arc chute (as indicated by "S") Standard Auxiliary Contacts 2 normally open (NO) contacts (as indicated by "/22") Standards Compliance IEC/EN 60947-4-1, UL 508, CSA C22.2 No. 14 Mounting Screw mounting via integrated feet or mounting plate. Connection Large screw terminals for main power connections and cage clamp terminals for auxiliary contacts and coil.
