Liebert Interceptor®II TVSS
Setting the Standard for Facility-Wide Protection

The Capacity to Handle the Surges;
The Footprint that Saves You Space
Today’s businesses demand more protection from their surge suppression
products. A power disturbance can strike at any time, causing a loss of data,
productivity and money. Customers require systems that will consistently
provide clean power and safeguard their equipment from the substantial
costs of power disturbances.
Features
n
Built-In-Testing - The Liebert Interceptor II 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.
n
Precise Current Sharing Assures Performance and Long Life - High
Energy current diversion is handled by a sophisticated parallel system
of computer matched, custom metal-oxide varistor (MOV) array.
n
Protection From Exteme Voltage Conditions - Individual
component-level fusing coordinates to ensure each unit is safeguarded.
n
Lowest Clamping Voltages - through use of low impedance copper
conduction plates.

How To Specify The Appropriate Model:
All Liebert Interceptor II model numbers begin with the SI prefix. Use Chart A to build your Liebert Interceptor II starting with the Surge Rating column.
Moving left to right, choose the correct configurations from each column for your application. Your completed model number should look similar to the
example below or SI016120YARDE. Refer to Chart B for Liebert Interceptor II dimensional data.
