Eaton’s Metal-enclosed switch and breaker (MSB) provides safe, reliable switching and fault protection for medium voltage switchgear applications. Combining a visible load-break disconnect switch with the capabilities of a fixed-mounted vacuum circuit breaker and control devices, the 5/15kV switchgear increases system protection and improves coordination with upstream and downstream devices.
Metal-Enclosed switchgear accommodates voltages from 1kV to 15kV, up to 1200A continuous current, and up to 40kA short circuit withstand
Designed for deployment in new and retrofit substation installations
Can be used as the primary main device integrated with fused feeder switches, or as primary protection in single-ended substations
Indoor and outdoor configurations available
Type MEB vacuum switchgear meets or exceeds the following industry standards: ANSI/IEEE C37.20.3. ANSI/IEEE C37.20.4, ANSI C37.22, ANSI C37.57, ANSI C37.58, NEMA SG5, NEMA SG6, CSA 22.2 No. 31. CSA listed for Canada and U.S. markets.
