Its housing is formed by press mould with export flame retarding polycarbonate of heat resisting 140℃, its core adopt quality silicone steel belt, and its secondary wire adopt high strength enamel insulated wire. 2.Technical feature ♦ Primary current 5-6300A, secondary current 5A, 1A, 0.1A, 0.05A    Protection CT primary current 200-6300A, secondary current 5A, 1A, 0.1A, 0.05A    Zero sequence CT primary current 0-5A, secondary voltage 1V or current 2mA.20mA    Dual-winding CT primary current 5-6300A, secondary current 5A, 20mA, 1A, 20mA ♦ Normal voltage: AC0.66kV ♦ Normal frequency: 50-60Hz ♦ Temperature: -30℃~70℃ (max. resistible 120℃) ♦ Altitude < 3000m ♦ Isolation: 3000V/1min 50Hz ♦ Used In place without rain and snow, without severe pollution and acute shock   3.Specification       The selection of specification product is based on related parameters such as primary current, bus section etc* Primary wire passes through window of transformer. Opening the flip cover, connecting secondary wire by lug, after leading out the secondary wire, restoring the flip cover When power metering, lead sealing small hole of flip cover to prevent electric larceny. Type Premary Current Secondary Current Function Accuracy 30 I AC 5A~6300A AC 0-1A, 0-5A, 0-20mA Normal 0.2s, 0.5s, 1s P-40 I/60I AC 250A / 800A AC 0.5A For motor protection 0.5s S 30I AC 5A~6300A AC 1A/20mA , 5A/20mA Double loop tranducer 0.2/0.2, 0.5/0.2, 1/0.2 L 35 AC 5A AC 20mA, 2mA, 1V Leak current transducer 0.2s, 0.02s BA05 AC 0.5~600A DC 4~20mA, 0~20mA, 1~5V, 0~5V For motor protection 0.2s, 0.5s   ♦ Long time working current does not exceed 110% of rating. 120% of rating may be used in short time; duration does not exceed 1h; ♦ Based on detected current, select the rated current and rated current ratio, generally above 2/3 load current; ♦ Product polarity indicate: P1, P2 mark for primary wiring; S S2 mark for relevant second wiring; S1 indicate same name end of PI; S2 indicate same name end of P2. ♦ Measure meters are connected on S1 end, S2 end, and the total impedance (including wire) shall not exceed the rated load of the transformer. If the meter mount position is far from current transformer or the circuit load is heavy, the preferable selection is specification for 1A ♦ based on spec, and number of bus, select the transformer with proper matched window.
