High-speed open transition transfer of electrical loads from normal to emergency source upon a reduction or loss of voltage and retransfer of load when normal power is restored
First UL listed medium voltage transfer switch
3-pole construction
Adjustable center-off time delay is factory preset to a default of 3 seconds but can be reset in the field via the front panel display and keypad
Center-off positioning is ideal for sophisticated load shed control schemes and prevents latch-up of SCR power devices during transfer between asynchronous power sources
Electromagnetic linear actuators provide reliable, trouble-free operation
Innovative proprietary lifetime arc suppression system minimizes effects of arcing.  
Isolated with high dielectric polyester glass insulation throughout

Control components and wiring can be replaced without removing the transfer switch from its enclosure
