Kumsung energy-saving electromagnetic contactor series

Unlike existing contactors that maintain a closed circuit by supplying an always-on control power, the Kumsung PMC series energy-saving electromagnetic contactor uses a latch and valve mechanism (physical force) so that up to 97% energy can be maintained (patent applied).
- Vibration-free contact maintenance: Contact surface protection and maximized life cycle
- Noise-free contact maintenance: A mechanical structure is used to maintain a closed circuit.
- Escapes from the effect of voltage wave with a consistent pressure
- Closed circuit is maintained with one-time (approximately 0.02 seconds) control power
- 97% or more reduced standby power and 99% removal of heat of the electromagnetic coil
- Quality resin and metal with excellent thermal/weather resistance
