Surge Protection
For Business-Critical Continuity™
Liebert SH Hybrid Series Surge Protective Device
Setting The Standard For Mission Critical Applications
Multi-Stage System Of Suppression
Hybrid Technology
The Liebert SH Hybrid Series is the first hybrid product in the industry to offer a true, coordinated multi-stage system of
suppression. It integrates the fast response time of the Silicone Avalanche Diode (SAD) with the high-energy capability
of the standard Liebert SI Series (Interceptor™) MOV (Metal Oxide Varistor).
Features
Liebert SH Hybrid Series builds upon industry standard Liebert SI Series
Self-sacrificing: This system
(Interceptor™) design. Unique benefits include:
— Patented component level monitoring — including neutral to ground.
— Unique sand-packed silver fuse network UL Rated at 200kAIC for safety.
— Highest surge current capability and survivability in the industry.
All surge suppression components used are computer tested and
matched. SAD’s are matched to +/- 1% and MOVs are matched to 1 volt
for optimum reliability and long life.
Matched low impedance buss system for both SAD and MOV modules.
Technology of choice for speed, allowing picosecond response time.
Built-In-Testing - The Liebert SH Hybrid Series comes equipped with a
built-in testing circuit that monitors MOV/fuse link status. The built-in
testing can be operated by the simple push of a button on the display
panel, and testing can occur at any voltage within the continuous
operating voltage range, even during a transient event. No other surge
manufacturer offers this monitoring capability as a standard feature.
ANSI/UL 1449 Third Edition Listed for Type 1 installations.
10-Year Warranty for parts and 5-Year on-site labor.

significantly degrades or fails with
nominal fluctuations or high-energy
events. This design is extremely
inconvenient to the customer,
and more importantly, it leaves
and opportunity for critical load
upsets/failures.
Oversize components: Large
components allow the system to
deal with the nominal line voltage,
as a result clamping levels increase,
defeating what it is designed to do.
The Liebert Answer:
The Transitional Method
A closely regulated amount of
energy is transitioned between
the primary SAD module and
the secondary MOV module.
The primary/secondary hybrid
design takes advantage of the
tight clamping and rapid response
characteristics of the SAD while
incorporating the high-energy
handling characteristics of the
MOV module. This is accomplished
through an impedance matching
network utilizing a series of
controlled copper geometries
in conjunction with custom
engineered high-voltage/highenergy component distribution. This
ultimately limits the amount of highenergy surge current through the
SAD module to an acceptable level
and diverting the remaining surge
current through the MOV module.
