Intelligent Bypass-Isolation Transfer Switches
Inspect, test and maintain power transfer switches without any power interruption. PTS WN3B is a series of Closed Transition Transfer Switches that delivers closed transition overlapping of sources in less than 100 milliseconds. It thrives on its capability to transfer in a closed transition mode when both sources are within the specified parameters.
Maximum Reliability and Operating Life
PTS-WN3B Series switches are positively locked, making it unaffected by momentary outages. This allows contact pressure to be maintained at a constant value as well as contact temperature rise to be minimised for maximum reliability and operating life. When a source is not within specified limits such as during a power failure, PTS-WN3B series operates in a delayed transition mode.
