ABB Low Voltage Installation Contactors are designed according to international standards (IEC), European standards (EN) and French standards (NF CUTE, DIN-VDE, BS).
We consider 2 types of "Installation Contactors" for different applications : "Normal " Installation and "Day-Night" Installation. They are essentially used in automated building equipment, industry and offices for terminal circuit controlling less than 40 kW AC-1 (incandescent lamps, fluorescent lamps, convectors heating, batteries, regulation systems, ovens, drying systems), small motors controlling less than 15 kW AC-3 (ventilation, air conditioning, pumping, watering, automatic systems) and unbalasting systems in energy management (possibly enslavement from clocks, unballasting relays, telebreakers, thermostats).
  • Mounting on rail DIN 35 mm (EN 50022) for switchboard.
  • Mounting depth: 58 mm
  • Width included from 1 to 3 modules (1 module = 17.5 mm)
  • The magnetic circuit design ensures a completely silent operation, the coil is supplied by AC (type ESB 20) or by an integrated diode rectifier (type ESB 24, ESB 40, ESB 63)
  • Terminals are delivered in open position
  • Protection against accidental direct touch
  • Extensions 2, 3,or 4 poles depending on the ratings, without built-in auxiliary contacts
  • 2-pole auxiliary contacts for type ESB 24, ESB 40, ESB63 (addition of one 2-pole block type EH 04 .. for module).
  • Sealing cover
  • Distance piece
