Introduction
Features and Benefits
Surge Protective Devices (SPD) have become a standard component
in today’s data centers, office buildings and manufacturing facilities
because they improve equipment uptime and reduce expensive
facility equipment repairs. GE’s SPD have always been regarded
as best in class. These important components are now available
factory-mounted inside GE’s Zenith Automatic Transfer Switches
(ATS) for optimal facility equipment protection.
Expensive, business-critical equipment is at risk from both high
magnitude lighting and utility switching surges and lower magnitude
surges caused by such inductive loads as HVAC, motors, fluorescent
light banks and even laser copiers. For this reason, IEEE guidelines
specifically recommend that a SPD be installed at service entrance
locations and in all downstream distribution components that
supply sensitive loads – such as an ATS.
Integral SPD are factory wired to the load-side of the ATS to minimize
lead lengths and provide the highest possible surge protection for the
connected critical loads. The integral mounting conserves wall
space and reduces installation costs.
GE’s full range of HE (high exposure) and ME (medium exposure)
SPD products are available integrally-mounted in GE’s Zenith
ZTE, ZTS and ZTG Series ATS products. All are factory tested
and guaranteed to provide the highest level of surge protection
for your critical loads.
