The Crouse-Hinds series MTL ZoneMaster PRO range of surge protection devices combines all the advantages of all mode protection with features and options to meet the needs of the most complex protection requirements. The ZoneMaster PRO range is available with surge current capacities of 200kA, 240kA, 340kA and 400kA. This along with the different international voltages available make the ZoneMaster PRO the most versatile product on the market.
ZoneMaster PRO range features modular construction, individual modules are bolted to a large surge return plate to minimize transient impedance. These color coded replaceable modules with a UL94-5V rated plastic casing are supplied mounted within a durable metal enclosure. The ZoneMaster PRO units are easy to install via simple surface mounting or optional flush mounting.
Large block Metal Oxide Varistor (MOV) protection technology is utilized within all the ZoneMaster PRO range. Each of the large block MOVs are individually fused for both thermal and short circuit protection. This provides redundancy ensuring the facility is never unprotected.
The optional power filter has a noise attenuation of 75dB at 100kHz - 100MHz and will attenuate 6kV transients down to just 200 volts. This power filter is UL1283 Listed and all ZoneMaster PRO devices are UL1449 5th Edition Listed.
