3. General
The AQ-101LV (AQ-101DLV) point sensor device is a sophisticated microprocessor-based arc flash
protection unit that includes complete self-supervision. The device is designed to minimize the damage
caused by an arcing fault (arc flash) by tripping the circuit breaker which supplies current to the fault.
The complete system self-supervision functionality of AQ-101LV (AQ-101DLV) provides the highest
level of dependability as it continuously monitors all internal system functions as well as all external
connections.
The AQ-101LV (AQ-101DLV) device is designed according to the latest protection relay standards and
is therefore suitable for installations in rough environments. These include utilities and power plants
(both traditional and renewable), various heavy industry applications (off-shore, marine, oil, gas, mining,
steel, etc.) as well as commercial and institutional electrical systems. While AQ-101LV (AQ-101DLV) is
suitable for MV use, it is designed for LV switchgears and for motor control center applications in both
new and retro[tted installations.
3.1. Dimensions and installation
AQ-101LV can be either door-mounted or panel-mounted in a standard 19 inch rack. The unit's
dimensions are as follows:
• Height: 177 mm (7.00")
• Width: 50 mm (1.97")
• Depth: 162 mm (6.38").
The dimensions of the AQ-101DLV variant are as follows:
• Height: 110 mm (4.33")
• Width: 145 mm (5.71")
• Depth: 43 mm (1.69").
The [gures below present a side view of the two device variants and give the dimensions in more
detail. The [rst one shows the dimensions of the panel or rack mounted unit, while the latter shows
those of the DIN rail variant. Please note that all values are given in millimeters.
