The MTL ZoneSentinel surge protectors are engineered for applications at distribution boards and small service locations and provides cost effective, high capacity surge protection to 100kA per phase. When used at a local panel in combination with a ZoneMaster at the service entrance, ZoneSentinel provides the ultimate in surge protection. The ZoneSentinel offers ten mode protection and, like the ZoneMaster range, has remote indication capabilities.

ZoneSentinel units offer a 100kA surge handling capability with protection between Line to Neutral, Line to Ground, Line to Line and Neutral to Ground and no restriction to the amount of load current. Thermal and short circuit fusing mechanisms are also included as an additional safety feature.

The MTL ZoneSentinel is modular in construction with individual modules bolted to a large surge return plate to minimize transient impedance. These modules, with a UL 94-5 rated plastic casing, are supplied mounted within a durable, corrosion resistant, NEMA 4X rated enclosure which can easily be drilled for cable access. ZoneSentinel units are easy to wall mount and flush mounting is also an option, should this be required. Individual modules are available upon request.

LED status indication is supplied with ZoneSentinel units as standard – normally open/normally closed contacts change state to indicate a fault. These contacts can be employed in a variety of applications from turning on lights remote from the surge protector, to interfacing with intelligent building management systems.

An optional remote monitoring unit is available for the MTL ZoneSentinel range, capable of monitoring the status of all panel mounted surge protectors in the facility. This unit provides audio and visual indication of protector status in one compact wall mounting case. Other features of the remote monitoring unit include a test switch which checks the monitoring circuitry and an audio alarm silence switch.

The optional power filter, for the Type 2 ZoneSentinel range, which is tested to ANSI/IEEE C62.41 and is UL 1283 listed, has a noise attenuation of just 75dB at 100KHz to 100MHz. The filter module will attenuate 6kV transients down to a mere 200V without the support of other surge components.
