Box Contents: Pack of 1. Apply thanks to the installation Protect automation processes to be measured in the building installation. They are preferred for switching and control of lighting systems, heating, ventilation, pumps, heat pumps and other drives of the building automation. The design of the type ESB 20 works with a AC Proper magnet system. The types ESB 24, 40 and 63 has a DC Magnet Drive and are therefore hum-free. That can be set noise that is a AC magnet hardly makes a sound. An integrated diode bridge enables connection to AC voltage. The built-in Varistor protects the reel from lightning surge and power surges up to 5 kV. Moreover, it Störspannungen Limited The magnetic system. The apron can be combined with Speicherprogrammierbaren controls. A Spulenbeschalung is required. The magnetic system is Funkentstört. Surges, be unique a power of max. 200 A or a power of max. 4 J or 1 million x A Power Of Max. 5 A or a power of max. 0.05 J (with normal shaft 8/20 µs). All Schaltglieder the apron are Altglieder and can also be used as a Hilfssch can be used Altglieder. The pins are fitted in such a way so as not Zwangsgeführt (N/O Contact and opener can overlap). In addition is available in the types ESB 24, 40 and 63 A 2-way auxiliary switches type EH 04 (1/2 MODULE Width) anbaubar. For switching of control signals this auxiliary switches to use.
