Instrument transformer TCM series

currentencapsulatedDIN rail mount

Current Transformers are essential components designed to be used with extensive power monitoring product portfolio. From simple energy meters to world class power quality meters, these proven products satisfy any requirement. Fixing system: to wall or to DIN rail by an accessory ; directly to cable by screws (the accessory and the screws are supplied together with the C.T.) MEASURING TRANSFORMERS The double terminal entry allows short circuit links to be fitted when it is necessary to disconnect the measuring instrument from the transformer without damage to the CT, or for easier termination to ground of the CT. TRANSFORMERS ELECTRONIC USE These transformers are used for measuring current from 25A to 600A (nominal primary current).The peculiar characteristic of these transformers is the high number of turns in the secondary cable. This makes it possible to have a very low secondary current, suitable for an electronic measuring circuit. The secondary current can be seen as voltage across a resistor. The resistor, of low power and cost, is directly fitted onto the printed circuit. Appliance sphere: current sensor for circuits which protect motors, UPS and similar; current sensor for measuring instruments (current probe). Insulation voltage between primary and secondary elements 4kV Frequency 50/60Hz Other characteristics on request
