n

Unique "Surge Current Transition

Circuit" allows for seamless

transition from primary (SAD

technology) to secondary 

(MOV array technology)

suppression system. A true,

shared suppression system.

n

Industry’s only Active Disconnect

System protects against system

failure and degradation due to

overvoltages.

n

Lowest UL 1449 clamping voltages

achieved—330VAC line to neutral

for a 120/208V Wye unit.

n

Technology of choice for speed,

allowing picosecond response time.

n

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.

n

Matched low impedance buss

system for both SAD and MOV

modules.

n

Liebert Hybrid Advantage builds

upon industry standard

Interceptor® Series design. Unique

benefits include:

— Patented component level

monitoring — including neutral 

to ground.

— Unique sand-packed silver fuse

network UL Rated at 300kAIC 

for safety.

— Highest surge current capability

and survivability in the industry.

— 10-year warranty on parts and 

5-year on-site labor, backed by

Emerson Power Service.

(250kAmp and 320kAmp current capacity units)

(substitute for xxx to complete model number)

Note: For other voltage configurations not listed, please consult factory.

The Liebert Hybrid Advantage features 

the fast response time of the Silicone

Avalanche Diode (SAD).
