“Open” Transition– Conventional 2-position ATS

– True double throw (no intermediate position)

– Single operator:

• Solenoids, charge & close mechanism, linear

motor, or solenoid (mfr. / switch type

dependent)

• Most reliable & cost effective method of

transfer

“Delayed” Transition– Other Aliases - Center-Off, Neutral position

– Dual Operators & Switching Mechanisms

• Intermediate position for hot-to-hot transfers

• 0-5 minutes (user selectable based on

applicable motor inertia)

• Commonly used as an alternate to in-phase

transfer

• NOT recommended for life safety/critical

branches; good option for equipment loads

requiring load shed (with paralleling)
