2 / 16 page K2CM 2 Current Reverse-phase Detection Models Note: The manual resetting method must be used with reverse-phase detection. ■ Related Product Transformer Note: Use this Transformer when a voltage reverse-phase detection model is used on a 400-V line. Specifications ■ Ratings Other features, such as 100% overcurrent capacity and flush mounting are also available. See Model Number Legend on page 1 for details. Note: The start-up lock timer restarts when the operating value at starting becomes less than 30% of the set current value.
