Surge protection for the NEMA power supply unit
Main range & features
VALVETRAB-SQ …
The VALVETRAB-SQ product range
includes surge protection devices for
American power supply systems. These have
been specially designed for the American
installation requirements.
Protection for all installation locations:
Service Entrance
– VAL-SQ SE (Service Entrance - for the
main supply)
– VAL-SQ SP (Sub-Panel - for the subdistribution panels)
– VAL-SQ CC (Control Cabinet - for the
control cabinet)
– VAL-SQ SI (Small Installation - for the
equipment).
VAL-SQ SE
The common use of protective devices
offers complete protection against
destructive surge voltages.
Protective devices can be mounted next
to the control cabinet or directly on
electrical devices.
The devices have a protective circuit with
high discharge capacity of rated surge
currents up to 200 kA per phase. The
Comprehensive protection
individual fuse for every protective path
integrated in the design lends additional
Cascaded (stepped) use of VAL-SQ
safety to the products.

Surge protection for the NEMA power supply unit
Surge protection devices
Device protection for the service
entrance
The VAL-SQ SE… provides maximum
surge protection for the service entrance.
These units are available with 120, 160 and
200 kA surge current ratings to protect
electronic equipment in industrial, medical
and commercial applications.
The VAL-SQ SE… utilizes a hybrid
suppression circuit, Sine Wave Tracking, in a
single, replaceable module. It provides both
transient protection and up to -30 dB of
noise filtration. Each surge suppression
mode is individually fused.

Surge protection for the NEMA power supply unit
Surge protection devices
Device protection for control cabinets
and small installations
The VAL-SQ CC is an economical
method of protecting electronic equipment
in light commercial, light industrial and
residential environments. Hybrid
suppressor circuit reduces leakage current
end products -30 dB of noise filtration.
The VAL-SQ SI… provides surge
protection in a compact, affordable package.
Each surge suppression mode is individually
fused.
