ROCKWILL®

Supply special design manual closing devicetechnology with own patent, It applied for normal and abnormal situation closing. It’s closing speed(time) comply with IEC62271-100. This function can offset from magnetic actuator fault which when actuator can’t work will cause the major accident.

Primacy incomer terminal (directly connect to interrupter reduce power lost)
Current sensor (external modular design easy for quality control and maintenance) Accuracy: ±0.5% Ratio:800/1

Vacuum interrupter (Adopt the APG technology, increasing the whole insulation and weathering performance)

Internal Voltage sensors incorporated within the vacuum interrupter module It’s equipped with two voltage-sensors, one for measuring the voltage of incoming side, and another one for measuring the voltage of outgoing side.

Shielded 4-conductor cable connection Voltage Sensor Accuracy: ±0.2 % Voltage Sensor Ratio:500/1 or 1000/1

High reliable manual opening device

Visible ON/OFF indicator and Counter

IP64 class waterproof plug connector

Apply ANSOFT design the high performance magnetic actuator, high reliable and free maintenance. Through 35,000 times opening reverse excitation test, the demagnetization rate less than 1%.








Note:

ROCKWILL? supply special patent modular design mono-stable type magnetic actuator with two coils controlling. It’s the best design for vacuum circuit breaker.
