  • Rated operational current: 16 A
  • Rated operational power: 7.5 kW at 400 V
  • Number of poles: 3-pole
  • Coil voltage: 24 V AC, 50/60 Hz
  • Auxiliary contacts: 1 normally open (1 NO)
  • Terminal type: Screw terminal
  • Size: S00
  • Dimensions: Height 58 mm, package width 50 mm, package depth 61.5 mm, package height 77.5 mm

How to use

Installation should be performed by qualified electrical personnel in accordance with applicable safety standards and wiring regulations. Mount the unit securely onto a standard mounting rail within a suitable enclosure.
