1 Installation Contactors ISU-xxx ISM-xxx Installation contactors are used in building technology switching cabinets of apartment blocks, office buildings, restaurants and hotels, shopping centres and hospitals as well as in industrial applications, production sites, logistics and warehouse technology for example. They are used here for automatic activation of electrical devices and units, alternating current and three-phase current motors, pumps, air conditioning systems, electric heaters and lighting technology or contacts Normally closed and / or normally open contacts High contact load 0A, A, 0A or A per contact Protective wiring Varistor for overvoltage protection Hum-free operation The built-in rectifier enables hum-free operation with direct and alternating current Special version ISM-xxx Additional manual operation possible A = automatic activation 0 = control voltage always off, no activation possible I = manual switch-on, the switch jumps automatically to the A position when the control voltage is applied Sealing cover Spacer ISD- ISP-0 ISP- ISP-0 Relmatic AG - Zuerichstrasse a - CH 0 Bruettisellen -
