Key Parameters Category Description / Value Product Line Eaton DMV (Contactor Relays) Model / Frame Size DMV400 Main Contacts 4 Poles Contact Configuration 4 Normally Open (NO) (as indicated by "4F") Rated Operational Current (Iₑ) For control loads, typically up to 10 A (at 240V AC) or similar, depending on the utilization category. Rated Thermal Current (Iᵼₕ) 20 A Rated Operational Voltage (Uₑ) Up to 690 V AC, 250 V DC Coil Control Voltage DC - The specific voltage (e.g., 24V, 48V, 110V DC) must be confirmed by the order code sticker on the device itself. The "CD" suffix is consistent with a DC coil. Utilization Categories AC-15: Control of electromagnetic loads (>72 VA) DC-13: Control of electromagnetic loads Electrical Durability Millions of operations (dependent on load) Mechanical Durability ~ 10 - 30 million operations Standards Compliance IEC/EN 60947-5-1 Mounting Snap-on mounting on 35 mm top-hat rail (DIN rail). Connection Cage Clamp terminal technology for easy wiring. Auxiliary Contacts Can typically be expanded with add-on auxiliary contact blocks (e.g., normally open or normally closed).
