Lightning arresters suit industrial environments
The Dehnbloc Maxi family of lightning current arresters from Dehn UK are single-pole devices that are ideally suited to use in exposed locations or in harsh industrial environments.
Surge arrester warns of its own failure
A new surge-protection device from Dehn UK incorporates a technique known as proactive thermocontrol to give an early warning of potential failures.
"Fortunately, at Dehn we have been working in Europe with the original IEC62305 standard for several years, which makes us uniquely able to advise customers on these new requirements.
Among the new products being featured at the event is the Dehnbloc Maxi family of lightning current arresters.
These single-pole devices are ideally suited to use in exposed locations or in harsh industrial environments, and are compatible with Dehn's existing Dehnguard Red/Line surge arresters, offering a flexible surge-protection solution independent of cable length and without the need for additional decoupling coils.
Also new is the Dehnguard TH275 LI surge arrester, which incorporates a technique known as pro-active thermo control to give an early warning of potential failures.
The unit features a three-stage green/yellow/red indicator along with a floating changeover contact that provides a remote signalling function, informing the user of the system's status.
If there is any risk that the varistor structure might be irreversibly damaged due to an increased energy load, users are informed by the yellow indicator and the remote signalling function.
The surge-protection module then can be exchanged for another unit before the installation becomes unprotected.
