Rockwill Electric Co., Ltd.

2. ++++General
The Rockwill’s new generation RCS-3N capacitor switch is a high efficient and economic type
vacuum switch that provides an operational life of over 10,000 (30,00open/close)
maintenance-free operations.
Using the RCS-3N will result in substantial savings from reduced maintenance and maximized
bank uptime and will also improve Power Quality.
The RCS all comply with relevant standards.
++++Using condition
Ambient temperature: -40 ~+85 , day temperature difference: 25℃ ℃ ℃；
Altitude:≤1000m area;
Wind speed no exceeds 35m/s;
No normally intensity vibration
No intensity erosion gas, medium place (for example acid, alkali, smother eg.)
Pollution class: IV class;
Charge temperature -40 ~+85℃ ℃。
++++Offering
RCS family provide with two options: RCS-3N economic type and RCS-3 long life type.
RCS-3 with Magnetic actuator mechanism
This advanced design monostable type
magnetic actuator. With mechanical life
100,000 times.(10 times of spring type
mechanism RCS-3N) with Intelligence
capacitor switch controller.
Note:
See details specification refer to RCS-3
catalogue.
RCS-3N type with Normal Spring mechanism
This normal type can only provide with spring
device and mechanical life is design for
10,000 times. Free maintenance operations
for 3000times.
Note:
Spring type mechanism RCS is cheaper cost.
