Eaton’s load interrupter medium-voltage switchgear (MVS) provides safe, reliable switching and fault protection. Designed for applications where high duty cycle operation is not needed, the metal-enclosed assembly consists of a 38 kV switch, bus and fuses. Offering cost-effective switchgear with characteristics vital to safety and coordination, the 38 kV MVS is designed to meet the requirements of multiple industries.
Available in stand-alone or line-ups, with indoor and outdoor configurations
Meets or exceeds IEEE C37.20.3 for metal-enclosed switchgear
Meets or exceeds NEMA SG5 and NEMA SG6
Quick-make, quick-break mechanism drives switch blades at high speed into either open or closed position
Switches can be supplied with manual or electrical operating mechanisms and with or without primary fuses
Can eliminate the need for protective clothing around the perimeter of electrical distribution equipment
Door interlocks ensure that the switch and fuse panels remain closed unless the switch is opened
Viewing window provides clear, visible confirmation of disconnected switch contacts
Through-the-door switch operation is provided to maintain arc-resistant protection while operating the switch
