Protect your process control equipment and communication interfaces against voltage spikes with this surge suppressor from WJ Furse. The unit safely grounds electrical faults caused by lightning and is able to handle a partial surge while still allowing the devices it's protecting to carry on working. This means you benefit from reduced downtime and improved productivity. Colour-coded terminals let you quickly distinguish between clean and dirty lines. For convenience, this component is supplied ready for flat mounting on its side or base.

Features & Benefits

• Flame-retardant polymer housing to reduce the risk of the unit contributing to a fire

• Low in-line resistance for minimal reduction in a system's signal strength

• Slim width of 7mm, so ideal for the compact protection of a large number of lines

• Wide operating temperature range of -40°C to +80°C for compatibility with demanding conditions

Applications

• Commercial and residential buildings

• Food and beverage industry

• Automated assembly lines

Where should I install this surge suppressor?

You can install this surge suppressor close to the equipment it's protecting or in series with a signal line, near where it enters or leaves a building.
