The Crouse-Hinds series MTL ZoneBarrier range is a unique, modular protection system for tele-communication equipment. By providing an effective barrier between uncontrolled transient environments and your valuable equipment the ZoneBarrier range protects you from costly system down time and equipment failure.
The sophisticated hybrid circuitry employed by the ZoneBarrier range protects your equipment without impeding normal operation. ZoneBarrier protection components comprise of a combination of solid state overvoltage protectors (sidactors) and positive temperature coefficient (PTC) devices to form three distinct stages of protection. This combination of high quality surge protection components gives the ZoneBarrier range its characteristic low limiting voltage and high surge current capacity which provides excellent protection.
All common telecommunication systems can be protected by the ZoneBarrier range. ZoneBarrier modules are available for Leased Line, Digital Data Service, T1, E1 and 2-wire ISDN and are available with a range of connection types.
