Microprocessor and Stored-Energy Switch Operators For Automatic Source Transfer Padmounted and Metal-Enclosed Switchgear 15 kV • 27 kV

Click here to view product detail pages.

Stored-Energy Switch Operator includes switch-position indicator, decoupling lever, decoupling indicator, operation counter, shaft to manually charge switch if control power is lost, ports for emergency manual tripping and pushbuttons for local operation. Decoupling lever isolates switch from the switch operator so that functional testing can be performed without opening and closing the switches . . . the load circuit remains energized.

Addressable Automatic Transfer Microprocessor Control at left has keypad entry and LCD display; event log to record operations; field-selectable settings for timers and operating parameters; and software intelligence to initiate control operations based on programmed settings.

Features • Source-voltage indicating lamps • Auto/manual selector • Automatic/hold return • Preferred/alternate source selection • Test buttons to simulate loss of source voltage, with pushbutton to return • Optional overcurrent lockout with test pushbutton provides blocking for faults internal to switchgear
