Eaton MTL Zonesentinel service entrance surge protector

The Crouse-Hinds series MTL ZoneSentinel range is engineered specifically for application at distribution boards and small service entrance locations. ZoneSentinel devices provide cost effective, high capacity power surge protection.  When used at a local panel in combination with a ZoneMaster at the service entrance, it provides the lowest suppression voltages available today.

ZoneSentinel units offer a 100kA surge handling capability with protection be-tween 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.

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.

An optional remote monitoring unit is available for the 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.

All ZoneSentinel units are UL 1449 5th Edition Listed. Models with 20kA ratings meet UL96A Master Label requirements
