SureSeT Switchgear Range
Description
Schneider Electric Square D SureSeT metal-clad switchgear powered by EvoPacT MV vacuum circuit breakers provides control and protection of medium voltage power equipment.
SureSeT switchgear offers a two-high circuit breaker design in a narrow 26 in. wide footprint that is fully compartmentalized for circuit breaker, auxiliary equipment, and low voltage compartment. SureSeT switchgear is designed to be configured in various combinations to meet customer requirements.
SureSeT switchgear with EvoPacT MV circuit breakers are tested in accordance with IEEE C37.20.2. EvoPacT MV circuit breakers are tested per IEEE C37.09. SureSeT switchgear and EvoPacT are UL and cULus Listed.

For more information, refer to the
SureSeT Medium Voltage, Metal-Clad, Indoor Switchgear User GuideOther service conditions
If operated beyond the normal service conditions, the circuit breaker is subject to accelerated aging.
The circuit breaker may only be used under conditions other than the normal service conditions with express written permission from Schneider Electric.
Storage
In order to preserve all of the device’s characteristics when stored for prolonged periods, we recommend storing the device in its original packaging, in dry conditions, and sheltered from the sun and rain at a temperature between –40°F (–40°C) and +158°F (70°C).
The maximum storage period is 12 months.
If the device was stored:
-
Between 6 and 12 months: perform basic preventative maintenance to help ensure a correct device operation.
-
Beyond 12 months: contact your Schneider Electric local service representative for device check-up.
Standards
SureSeT switchgear meets the following ANSI/IEEE standards:
-
ANSI/IEEE C37.20.2: IEEE Standard for Metal-Clad Switchgear
-
ANSI/IEEE C37.09: IEEE Standard Test Procedures for AC High-Voltage Circuit Breakers with Rated Maximum Voltage Above 1000V
