Adopt bolt fixing mode, convenient and fastSpecification:Item Type: 3 Phase Solid State RelayMaterial: PCInput Voltage: 380VACOutput: 40A 380VACControl Current: 20mAOn State Voltage Drop: 1.5VOn State Leakage Current: 5mAAmbient Temperature: -30-75Insulation Resistance: 1000M or 500VDCFixing Method: Bolt fixing.Package List:1 x 3 Phase Solid State RelayNote:1. If the load is 10A, a radiator must be installed, and if the load is 40A or more, fan forced cooling or water cooling should be added.2. When using an inductive load, be sure to connect a varistor in parallel with the output end, the value of which is 1.6and 8209 1.9 times the load voltage.
