Schneider Electric LC1D12B7 is a magnetic contactor from the Deca sub-range, designed with screw connections and three poles (3P; 3NO). It has a rated current of 25A for AC-1 and 12A for AC-3 at 440Vac. This contactor is suitable for DIN rail mounting and has a net width of 45 mm. It offers a degree of protection of IP20 and operates with a control voltage (AC) range of 19.2-26.4Vac at 50Hz and 20.4-26.4Vac at 60Hz. The LC1D12B7 is capable of handling a rated operating voltage (Ue) up to 690 V and includes 1 normally open (NO) auxiliary contact. It has a rated impulse voltage (Uimp) of 6 kV and supports rated active power of up to 7.5kW for various AC-3 voltage ranges. Additionally, it features 1 normally closed (NC) auxiliary contact and instantaneous auxiliary contacts type of 1NO+1NC. The rated power (HP) varies from 0.5HP at 115Vac in single-phase to 10HP at 575-600Vac in three-phase, under UL/CSA standards. Its mechanical durability is rated at 15 million operations at no load, and its electrical durability is rated at 2 million operations with load. The rated voltage (AC) for phase-to-phase is 690 V.
