ZoneMaster 300
The ZoneMaster 300 Series is engineered
to withstand the most severe transient
environment at large service entrance or
distribution panels, and provide decades
of uninterrupted surge protection. Dual
protection circuits provide redundancy
ensuring the site is always protected. The
ZoneMaster 300 provides the lowest
suppression voltages available, 150kA
surge capacity per mode, as well as full
protection in all modes (L-N, L-G, L-L,
and N-G).

Durable, lightweight, corrosion resistant high impact plastic. Ultraviolet stabilized UL94-5V rated.
NEMA 1, 2, 3, 3S, 4, 4X 12, and 13. Transparent cover for maximum visibility and safety.
12" x 12" x 6" (31cm x 31cm x 15.5cm).
Approx. 12 lbs. (5.5 kg)
Low impedance assembly. Modules are bolted (1/4" bolts) to a large surge return plate to minimize
transient impedance and suppression voltage.
#2 AWG max wire size
4" x 0.31" diameter holes 12 3/4" x 10" [30.5cm x 25.4cm]. Enclosure can be easily drilled for
conduit/cable access.
Power should be disconnected prior to module replacement. Remove two 1/4" nuts, unplug
remote indication connector and remove module. Estimated replacement time 2 minutes.
1 1/4" x 5 5/16" x 2 1/2" [3.2cm x 13.5cm x 6.4cm]
16" x 14" x 7" (41cm x 36cm x 18cm).
Approx. 20 lbs. (9 kg)
Ultra low impedance assembly. Modules are bolted to a corrosion resistant, tin plated copper bus bar.
No plug-in modules in the surge path.
0.31" (8mm) diameter holes 16 3/4" x 12" [43cm x 30cm]. Enclosure can be easily drilled for
conduit/cable access.
