The Crouse-Hinds series ZoneMaster All-Mode range of surge protection devices combines unparalleled power handling capability, application versatility, proven circuitry along with simple installation, features which make ZoneMaster All-Mode units the ultimate power protection solution. With 200kA, 240kA, 340kA and 400kA versions available and configurations suitable for all International supply voltages, ZoneMaster All-Mode is truly a versatile and flexible protection range.

ZoneMaster All-Mode devices are modular in construction, individual modules are bolted to a large surge return plate to minimize transient impedance. These color coded, replaceable modules, with a UL 94-5V rated plastic casing are supplied mounted within a durable NEMA 4X (IP66) rated enclosure. ZoneMaster All-Mode units are easy to install via simple wall mounting.

Large block Metal Oxide Varistor (MOV) protection technology is utilized within the ZoneMaster All-Mode range. Each of the large block MOVs are individually fused for both thermal and short circuit protection. This produces redundancy ensuring the facility is never unprotected.
