HAKEL SURGE REDUCTION FILTER – HKSF SERIES
Lightning Surges
Lightning surges are characterized by high rate
of current rise (di/dt) and high rate of induced
voltage rise.
This extreme rapid rises are the main causes of
damage to sensitive and critical equipment
resulting in down time and in some occasions
massive unforeseen financial losses

Surge Reduction Filters
Hakel’s comprehensive range of HKSF series arresters incorporating two port devices with built-in
primary and secondary protection complete with surge reduction filter provides massive energy diversion
and voltage clamping with stable and precise filtering features. These arresters should be installed prior
to the sensitive equipment to be protected, virtually guaranteeing overvoltage protection against lightning
surge which is the main cause of damage to sensitive and critical equipment such as advanced medical
equipment and telecommunication equipment.
Hakel HKSF series arrester encompasses 32A up to 200A for single phase and three phase.
current rating series arresters are available upon request.
Hakel HKSF high surge rating series arresters are suitable for highly exposed areas.
Higher
Highly effective two ports device with in-built primary and secondary transient protection stages
complete with series surge filter ensures the following:
* High performance 3 stages surge reduction
* Significant reduction in residual voltage
* Dramatically reduce di/dt and dv/dt up to 1000 times less reaching
the sensitive equipment
* Active MOV technology with high overvoltage withstand complying
with IEC standard and UL1449
* Indoor and Outdoor (IP55) versions
* Breaker incorporated to facilitate maintenance and replacement without power
interruption
* Audio and visual indication for arrester operational status
* 5 years’ warranty
Surge and Abnormal Voltage Protection
Primary protection is provided by the high current rating (KA) varistor which is incorporated with
mechanical fault indication. Secondary and N-E protection are also provided in this design. Wide range
of voltages for primary protection manifested in our SPC3 series cater for abnormal voltage variation that
can occur at site. This fault is normally due to voltage regulation or wiring fault such as open neutral.
The primary and secondary protection cover nominal voltage of 220V~240V with 280V maximum
voltage variation and a
higher voltage range ensure protection against
abnormal voltage up to 480V.
Mode of Protection
Hakel HKSF series arrester provides protection
in common mode and differential mode for both
single phase and three phase
Operation Status
Hakel HKSF series arrester provides detailed
operational status for primary and secondary
protection as well as power supply. This alerts
the user of any presence of damage or defective
arrester. The alarm can be deactivated with a
latched switch.
Filtering
Hakel HKSF series arresters provide extreme
suppression of voltage levels of high energetic
impulses which come into the protected equipment from the L.V. power distribution side.
The combination also ensures an attenuation of high frequency noise levels of a minimum 50dB at 5MHz
in the band of 0.1 to 30MHz.
