The 12 VDC coil draws 3.2 W closing and holding — a steady-state load that the control transformer or PLC output must supply continuously. Switching capacity varies by voltage: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V — derate accordingly for your load voltage.
Screw terminals accept 2x (0.25 to 2.5 mm²) solid or 2x (24 to 14 AWG) stranded. Depth is 73 mm, height 60 mm. Shock rated at 10g / 5 ms and 5g / 10 ms, so it holds up in mobile or high-vibration sections of the line.
The depth is 73 mm, width 45 mm, height 60 mm — size S00 footprint.
Screw terminals accept 2x (0.25 to 2.5 mm²) solid or 2x (24 to 14 AWG) stranded.
