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.

Inverse Type
Inverse time both at startup and during operation:
Timer scale × 1 (s) at 600% overload
Timer scale × 3 (s) at 200% overload
