Indoor Medium Voltage Switch and Fixed Breaker—MSB

Product Description

Eaton’s MSB switchgear

is an integrated assembly

of a visible load-break

disconnect switch, fixedmounted

vacuum circuit

breaker, and control devices

that are integrated electrically

and mechanically for

circuit protection. All

major components are

manufactured by Eaton,

establishing one source

of responsibility for the

equipment and ensuring

high standards in quality,

coordination, reliability and

service. MSB switchgear

would typically be used

where both cost and

protection are important

design parameters.

Medium Voltage Metal-Enclosed Switches

Medium Voltage Switch and Breaker—MSB

Application Description

Applications include ground

fault protection, primary and/

or secondary switching, and

protection on unit substations,

automatic transfer switching

at medium voltage levels,

capacitor switching, high

duty cycle and tight system

coordination protection.

MSB switchgear can also be

an economic benefit in singleended

substations because

it may allow the customer

to eliminate the secondary

main protection and

switching device.

vacuum switches combined

with solid insulation material.

This environmentally-friendly

technology avoids the use of

SF6

as an insulation gas.
