Automatic Transfer Switches

 

Camso is an automatic transfer switch manufacturers. Our automatic power transfer switches have reliable mechanical interlock, high arc-quenching performance and high transfer speed.

 W Series Dual-power Automatic Transfer Switches

  • The W Series belong to the PC level, and include the types of W2 and WN3. W-2 is a two-stage automatic transfer switch. After a switching signal is received the switch transfers power immediately from one source to the other without stopping at an OFF position in the middle. The rated current is 20A~500A.
  • The WN3 is a three-stage automatic transfer switch. After a switching signal is received the switch transfers power immediately, or after a preset delay, or stop at an OFF position in the middle. The rated current is 20A~5000A.

 Characteristics of ATS switches:

  • Reliable mechanical interlock: Special eccentric selection construction to ensure only one power source is connected.
  • High arc-quenching performance: Extinguishes abnormal electrical arcing, short duration of electric arcing and low contact loss.
  • Multi-disc main arc contract: Enhances the contact area and pressure of contact surfaces, eliminating overheating and contact welding and extending contact lifespan.
  • High Transfer speed: Rapid transfer between the active power and standby power, allowing a customized transfer delay for an ATS with a controller.
  • Simple construction and small volume: Have reliable operation, a low failure rate and are convenient to install and maintain. Allow rotation with a handle during repair for convenient error detection and troubleshooting. The ATS of the W series are at PC level, are smaller than those of CB level, but have a higher current rating.
