LUMEL CURRENT TRANSFORMER (CT) 300/5A CLASS-0.5,5VA50/60Hz Busbar: 30.5 x 10.5mm,LCTB 5030300300A55
Current Transformer is used for the measurement of electric alternating currents. When current in a circuit (primary current) is too high to directly apply to measuring instruments, a current transformer produces a reduced current (secondary current) accurately proportional to the current in the circuit, which can be conveniently connected to measuring and recording instruments. A current transformer also isolates the measuring instruments from what may be very high voltage in the monitored circuit. Relationship between primary and secondary currents is called rated transformation ratio.
