Singled phased motors are widely used in home applications. they are operated directly by switch. MCB of mechanical starters which does not provide sufficient protection to motors and does not isolate the application in case of power failure Electronics single phase motor starters provide protection to motor against over current, high voltage and isolates the motor in case of power failure.
Starters are available in elegent, dust proof ABS Plastic enclosure with different colours like white gray, ivory and wipro gray.
| Operating voltage | 140 to 285 V |
| Current range | 2-5 Amp, 4-10 Amp, 8-14 Amp, 10-16 Amp, 14-22 Amp |
| Overload tripping | As per inverse time current characteristic. |
| High voltage cut-off | 285 V |
| Cut-in | 270 V |
| On-off/reset | By manual push button |
| Indications | Green - motor on red – overload |
For conventional single phase motors like Grinders, Polishers,Geysers,Wood working machines etc. provides overload and high voltage cut-off for any applience.
For Compressors/Air conditioners/Water coolers. Exhaust fans in factories and theaters.provides three minuits time delay in auto restart and auto/manual facility.
For unattended pumps. Build in dry-run protection with 30% to 70% adjustable dry-run current.
