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 < 40 kW AC-1 (incandescent lamps, fluorescent lamps, convectors heating, batteries, regulation systems, ovens, drying systems), small motors controlling < 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
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
Accessories
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
