The Crouse-Hinds series MTL ZoneMaster range of surge protection devices combines unparalleled power handling capability, application versatility, proven circuitry along with simple installation, features which make these units the ultimate mains power protection solution. With configurations suitable for all International supply voltages, ZoneMaster is truly a versatile and flexible protection range.
ZoneMaster devices are modular in construction. Individual modules are bolted to a large surge return plate to minimise transient impedance. These colour coded, replaceable modules, with a UL 94-5V rated plastic casing are supplied mounted within a durable IP66
rated enclosure. ZoneMaster units are easy to install via simple wall mounting, although flush mounting is also an option.
Large block, 3 terminal Metal Oxide Varistor (MOV) protection technology is utilised within the ZoneMaster range. The dual protection circuits of ZoneMaster 150 devices provide full redundancy ensuring the site is never unprotected. All ZoneMaster units also include thermal and short circuit fusing for additional safety.
The optional mains power filter has a noise attenuation of 75dB at 100KHz- 100MHz and will attenuate 6kV transients down to just 200V. This mains power filter is UL 1283 Listed and all ZoneMaster devices have UL 1449, 5th edition Listing for added peace of mind.
