CITEL MJ8-C6A

UL497B Listed Data Line Surge Protector for Category 6A Ethernet

Datasheet
Contact Us

Data Network: up to 10Gbps, RJ45, 8W+Shield+Ground

Application: Cameras, Ethernet Switches, Wireless Radio

In order to limit the effects of lightning or switching transients to acceptable levels for critical equipment and installations, the most effective solution is to install a protection device against these events. We call this an "SPD" (Surge Protective Device), they are deployed into the wireless network at the input to a distribution bus or directly at a sensitive load. The purpose is to harmlessly divert damaging surges away from your sensitive equipment before any disruption occurs.

Surge Protection for Industrial Control Panels (UL508A)

UL508A Industrial Control Panel

OVERVIEW

Today's increased reliance on very sensitive electronics makes surge protection an important topic for Industrial Control Panels listed to UL508A. The Insurance Institute for Business & Home Safety study found that $26 billion dollars was lost due to non-lightning power surges. In addition, there are about 25 million lightning strikes in the US each year that cause between $650M to $1B in losses according to the Insurance Information Institute, State Farm©.

Selecting SPD for UL508A Industrial Control Panels

NEC/NFPA 70 require that Surge Protective Devices (SPDs) shall be UL1449 Listed. This means selecting a surge protector is easier than it has ever been. There are only a few choices available for SPDs that are UL Listed for any of the most commonly used surge standards including UL1449 5th Edition, UL497B, and UL497E.

Determining the acceptability of an SPD
for UL 508A Industrial Control Panels and All Other UL Listed Equipment

The UL inspector will first consider the SPD type when determining it’s acceptability for a given application or piece of equipment. This will include UL 508A as well as all other UL Listed equipment. The first level compliance is based on the UL Approval (LISTED or RECOGNIZED) of the SPD or UL SPD Type and it’s Suitable Ratings. This means that it has to meet all safety, performance, environmental and electrical system ratings of the application. If any of these criteria are not fully met, it will require a Procedure Description, a File Update and/or Additional Testing. These actions will require additional costs that may be substantial. For this reason, it is in the interest of the specifier to use UL LISTED SPD’s to eliminate any uncertainty or to make sure the UL RECOGNIZED SPD is selected at the time of UL submittal of the equipment.

A UL field inspection of the control panel with the SPD installed is required as a part of a standard follow-up service visit.

YesYesYesYes – All UL recognized SPD’s require a UL engineering evaluation of the SPD’s existing UL1449 E–file.

This will result, at a minimum, in a cost to update the UL file and may also require testing that would result in additional costs.
