Protection Switches

Medium and low voltage protection switchesWeather-type cells (IP65) steel plate built in A37-24 of 2.5 mm. Inside features a fuse switch class 24 kV SF6 to operate under load. You can also incorporate a vacuum switch.Bar has input and output for connecting to terminal MUFAs flat ground connectors inside and out.The operating mechanism is independent of the operator, openingautomatically if any of the fuse operates. It is equipped with auxiliary contacts, 2 NO / 2 NC and opening coil (shooting) at 220 Vac. Robust design and high security that prevents ground connection without open (deenergized) the main switch.The inner door of access to fuses, has a lock that prevents access if the computer is closed (energized). Also incorporates a 120 W heater operated by thermostat. The interior and exterior doors have tempered glass peephole safety inspection. The interior is illuminated with a turtle-type lamp and 3 LED indicators for voltage at the output. The input and output cables for their network socket is lower through perforated metal covers for the installation of packing and soensure tightness. He performed in our lab tests applied voltage, resistance and simultaneous contacts, issuing a test certificate and guarantee of 24 months.Meets design requirements for nominal current.LV cellThe cell type IP 65 weatherproof with similar characteristics to the cell MT, comprise the following elements:€¢ 4 terminals LV (phases 1, 2.3 + neutral), wiring the switch of BT€¢ output connections tinned copper plate.€¢ Has the emergency stop button, turtle lamp inside, storm door and LED indicators of stress.
