Product Description
Its 250/5 A ratio and 0.5 accuracy class provide a standard 5 A secondary signal for ammeters, power meters and relay protection. The busbar/window construction and cast-resin insulation give good dielectric strength and moisture resistance. With a rated burden of 5-3.75 VA it suits panel-mounted metering in LV switchgear. The Saiwei LMZ-0.66 is a ring-type (donut) low-voltage current transformer designed for 0.66 kV indoor AC distribution and metering.
Basic Product Information
- Ring-type (donut) aperture design for through-busbar or cable primary conductor
- Cast-resin insulation rated for 0.66 kV low-voltage systems
- Rated burden 5-3.75 VA with a standard 5 A secondary output at 50/60 Hz
- 250/5 A current ratio with 0.5 accuracy class for metering and protection
Technical Specifications
Version & Model Difference
The LMZ-0.66 family covers many primary currents (from about 50/5 A up to 2000/5 A) and several aperture sizes (phi22 to phi62). This listing is the 250/5 A, 0.5-class, ring-type version; verify the ratio, accuracy class and burden moulded on the nameplate, since secondary ratings differ per variant.
Application Scenarios
- LV switchgear ammeter and power meter inputs
- Energy metering in 0.66 kV distribution panels
- Motor control centre (MCC) load monitoring
- Relay protection and SCADA current sensing
