Product Features

● Clamp-On Split Core: A Φ38mm window opens to fit a cable or busbar without disconnecting the line.

● 0.5 Class Accuracy: 0.5 metering class, with 0.2 class available as an option.

● 2.5-5VA Rated Capacity: A burden range that covers standard metering and monitoring duties.

● 50A-600A Primary Range: Primary current specified to the installation.

● 5A or 1A Secondary Output: Standard secondary output.

● High-Permeability Silicon Steel Core: Stable measurement across the 50/60Hz range.

● IP54 Enclosure, UL94 V-0: Dust and splash protection in a flame-retardant housing.

● 3kV/min Isolation: Insulation between the primary and secondary circuits.

● IEC/GB Compliance: Designed to the IEC and GB standards.

Product Advantages

● Install without cutting the line: the hinged core clamps around an existing conductor, so metering can be added during a planned outage instead of a rewire.

● Accurate metering: 0.5 class accuracy, with 0.2 class optional, suits energy metering and power-quality monitoring.

● Wide current range: primary currents from 50A to 600A can be specified.

● High-permeability silicon steel core: low core loss and a stable secondary signal across the 50/60Hz band.

● Rugged enclosure: an IP54 housing in UL94 V-0 flame-retardant plastic suits control cabinets and industrial installations.

● Safe isolation: a 3kV/min isolation voltage separates the measured circuit from the secondary wiring.

● Marked for correct orientation: the P1 inlet and P2 outlet markings show which way the conductor must pass through the window.

● Two secondary options: a 5A or 1A secondary output matches either standard panel meters or 1A metering inputs.
