As the source prints itTransfer Switch MechanismThese switches are used with a single-phase system when the single-phase NEUTRAL line is to be connected to a neutral lug and is not to be switched. Solderless, screw-type terminal lugs are standard.
This transfer switch is suitable for control of motors, electric discharge lamps, tungsten filament and electric heating equipment where the sum of motor full load ampere ratings and the ampere ratings of other loads do not exceed the ampere rating of the switch and the tungsten load does not exceed 30 percent of the switch rating.
This UL listed transfer switch is for use in optional standby systems only (NEC article 702).
This transfer switch is suitable for use on a circuit capable of 10,000 (100A) symmetrical amperes, 240 VAC maximum.Press to see it in the sheet ↓

- Equipment Description
- The automatic transfer switch is used for transferring electrical load from a UTILITY (NORMAL) power source to a GENERATOR (STANDBY) power source. Such a transfer of electrical loads occurs automatically when the UTILITY power source has failed or is substantially reduced and the GENERATOR source voltage and frequency have reached an acceptable level. The transfer switch consists of a transfer mechanism and an integrated PCB.1
