Technical Specifications
Primary current: 150A. Secondary current: 5A. Ratio: 150/5A. Accuracy class: 0.5. Rated voltage: 0.72kV. Frequency: 50/60Hz. Burden: 5VA. Mounting: busbar or cable. Operating temperature range: -25°C to +55°C. Protection rating: IP20.
Functional Features
High accuracy class 0.5 supports precision metering. Window-type design enables easy installation over existing busbars or cables. Tape-insulated construction for safety. Compact design saves panel space. Conforms to IEC 61869 standards.
Application Scenarios
It is used for current measurement in low-voltage switchgear, motor control centers, distribution panels, energy metering systems and industrial electrical protection circuits.
Performance Parameters
Accuracy: ±0.5% at rated current. Ratio error: <±0.5%. Phase error: <15 minutes. Burden: 5VA. Operating temperature range: -25°C to +55°C.
Material Composition
Core: grain-oriented silicon steel. Windings: enameled copper wire. Housing: flame-retardant thermoplastic. Terminals: tin-plated copper. Insulation: epoxy resin.
Structural Characteristics
It features rectangular window-type core, tape-insulated winding, thermoplastic housing, secondary terminal screws, and mounting lugs.
Working Principle
The primary conductor passes through the transformer window, creating a magnetic field proportional to primary current. This field induces a proportional current in the secondary winding, which is used for metering, protection and control circuits.
Installation Requirements
Mount over busbar or cable through the window. Connect secondary circuit to metering or protection devices. Ensure secondary circuit is never open while energized. Mount in vertical orientation. Tighten terminal screws to specified torque.
