Qo surge breakers QO2175SB square d arrestor lot
1-Surge arrester modules ,BRAND NEW IN BOX , AWESOME DEAL,for plug-on load center panel mounting is simple to install. Designed to fit Square D type QO Load Centers, NQO or NQOD Panelboards, or Combination Service Entrance Devices (CSED) requiring two adjacent pole spaces. Installation is completed by connecting the single white wire to the panel's neutral bar.
This one device will protect your entire downstream electrical system. Designed for use on single-phase,(Residential Homes or commercial) three-wire 120/240 Vac, 50/60 Hz electrical services. The LED on the face of the unit indicates operational status of the arrester. If the light is on the unit is fully operational. When the LED indicator goes off, the unit should be replaced. Instructions included, in original box
The QO2175SB are UL and C-UL Listed secondary surge
arresters and TVSS. It is designed for use on single-phase, three-wire
120/240 Vac, 50/60 Hz electrical service. Two QO2175SB secondary surge
arresters can be installed to protect 208Y/120 Vac three-phase, four-wire
The QO2175SB surge arresters offer the following
UL and C-UL Listed secondary surge arresters
UL and C-UL Listed to UL1449, Second Edition as a TVSS
Suitable for use in Category B and C locations
LED indicates operational status
Metal oxide varistor (MOV) design
Excellent clamping voltage performance
The QO2175SB plugs on to the branch circuit spaces of the interior of a
QO Load Center, NQO or NQOD Panelboard, or combination service
entrance device (CSED) from Square D . Installation is completed by the
connection of the single white wire of the QO2175SB to the panel s neutral
MOVs provide voltage surges with a low resistance path line-to-line, line-toneutral,
or line-to-ground while providing a high resistance path to the
50/60 Hz power source. The MOV responds faster and has a lower
clamping voltage because it does not have a gap structure.
Fuse Links and Thermal Cut-Offs
Individual non-replaceable internal fuse links and thermal cut-offs protect
each MOV and open in the event of a varistor-damaging overload. Silica
inside the arrester housing reduces the risk of one fuse damaging another
The LED on the face of the device indicates operational status of the
arrester. If the light is on the device is fully operational
