PTS WN3 Automatic/Manual

Automatic and reliable transfer of mission-critical loads for business continuity.

PTS Low-Voltage (LV) Automatic Transfer Switches

The industry standard for high-speed transfer of loads

Reliable and field-proven solenoid operating mechanism are what propelled PTS-WN3 Series Automatic Transfer Switches to be recognised for its high-speed transfer of loads between alternate sources of power regardless of ampacity size. Combine it with a programmable microprocessor controller with LCD Display, and what you’ll get is the most advanced method of transferring all types of loads, USPs and microprocessor-based systems. They are available open or enclosed, in ampacity sizes from 16 through 6300 amperes with the largest selection of optional accessories offered worldwide.

Maximum reliability and operating life

PTS-WN3 Series switches are positively locked hence unaffected by momentary outages. In doing so, contact pressure is maintained at a constant value and the contact temperature rise is minimised for maximum reliability and operating life.
