Installation contactors

Modular DIN rail components

ESB installation contactors  are mainly used in buildings for switching and controlling lighting, heating, ventilation, motor and pumps. They are designed to match the ABB modular DIN rail components and can be integrated easily in dedicated panels. EN contactors have a built-in toggle switch for automatic and manual application.

Main benefits

  • Powerful for lamp switching
  • ESB24 … ESB63 are hum free and with low power consumption
  • Significantly reduced space compared to industrial contactors
  • Better logistics thanks to AC/DC coil that requires less variants

Main features

  • ESB contactors up to 63 A 400 V AC-1 or AC-7a with 2 to 4-pole version
  • EN contactors up to 40 A, 400 V AC-1 or AC-7a manually / automatic operated
  • ESB20, EN20 operates with an AC coil. ESB24...63, EN24...40 are fitted with a DC coil 
  • A varistor protects the coil against remote lightning strikes and overvoltages (ESB24 … ESB63)
