ASCO ADTS 150-400A 3-Phase 3-Pole Transfer Switches

The ASCO ADTS 150-400A 3-Phase 3-Pole Automatic Delayed Transition Transfer Switches offers a standard three phase solid neutral switch with enclosure. Many voltage and amperes options available for indoor or outdoor commercial applications. The most common transition modes are open, delayed, and closed transition sequences. Specifically for this section (ASCO ADTS 150-400A, Delayed Transition is similar to open transition in that there is an interruption between breaking the contacts for one power source and closing on the contacts for the alternate power source. However, the amount of time between these operations is typically adjustable. Delayed Transition is often used to avoid inrush currents associated with transferring motor loads between power sources.
