CT Electric Sensor

  Core Material Ferrite External Material Plastic Opening Size: 13 x 13mm/ 0.5 x 0.5" Output Plug: 3.5mm Dielectric Strength: 6000V AC/1min Working Temperature: -25-70°C Cable Length: 42"     If an unburdened CT (i.e. one without a burden resistor) is attached to a current-carrying conductor, the CT will generate an unsafe voltage at its leads which could break down the insulation and destroy the C.T. Our CTs have internal Zener diodes to limit the maximum unburdened voltage output to a safe level. CTs with internal burden resistors (‘the voltage output’ type) are also protected against developing dangerous voltages. Always connect the C.T. leads before clipping it round a current-carrying conductor, and always un-clip the C.T. from the current-carrying conductor before disconnecting its leads. Never open-circuit a C.T. whilst it is on a current-carrying conductor. It is always safe to short-circuit a C.T. Never attempt to fit a C.T. to a bare conductor unless you are absolutely cer
