Split Core Current Transformer CR3100 Series The CR3100 Series Split Core Current Transformer is designed to provide a low cost method to monitoring electri- cal current. A unique hinge and locking snap allows attach- ment without interrupting the current-carrying wire. High secondary turn will develop signals up to 10.0 VAC across a burden resistor.
