These 3 phase electronische tack load relay with power montioring incorporating4 functions in the right protection, left protection, motor protection relay and NOT-FROM-protection categories till 3 to switching, tack and protection from motors till 4KW. This simplifying installation considerably and saves lot of space of the mounting rail. The almost wear-free switching increases the lifespan by 10 times and also the plant availability. Programming of the rated current is only possible after pressing the RESET button for 6 seconds - a subsequent alteration or manipulation by unauthorized persons is nearly impossible. The semiconductor-reversing contactor can be driven directly over the SPS and dispose over remote -signal contacts.Left -/Right operation : Simple activation,inclusive of interlocking circuit. Motorprotection:comfortable protection through the electronic motor protection relays with automatic and remote -reset -function (wirestrap automatic after 20 min ,RESET -TASTER or e
