Application
The CBT/1 bar-type current transformers are designed for use in metering 600 volt circuits. For metering accuracy, the CBT/1 is rated to B-0.2.
Construction and insulation
The ring-type core and fully distributed winding are assembled to a glass filled polypropylene window liner and injection molded in thermoplastic rubber. The thermoplastic rubber insulating material is permanently molded to the core and coil assembly, resulting in a compact unit with excellent mechanical, thermal, and dielectric characteristics.
Secondary terminals and shorting device
The CBT/1 transformers are supplied with embedded compression-type secondary terminals, a short circuit device, and a clear, rectangular snap-on cover suitable for locking with a meter seal. This clear plastic cover allows a visual check of connections and is keyed to ensure the shorting clip is across the terminals when no wires are connected. This safety feature avoids dangerous voltages across the secondary terminals if the primary is energized. Terminals accommodate #14-6 wire and can also serve as a post-type connector by looping wire under the screw head.
Primary bar
The primary copper bar is electro-tin plated and can be rotated for convenient positioning of the transformer. It is equipped with a potential terminal suitable for #6 to #14 wire.
Base
The optional base is constructed of corrosion-resistant aluminum and secured to the encapsulated base support by four symmetrically located screws. Units ordered without a base are not equipped for future base mounting.
Test reports
Test reports are stored electronically and can be e-mailed in various formats at the time of shipment.
Standards
This unit meets or exceeds all requirements of IEEE C57.13-2016 and can be tested to other standards as requested
