Medium Voltage Metal-Enclosed Switches

Metal-Enclosed Breaker—MEB

Indoor Metal-Enclosed Drawout Vacuum Breaker—MEB

Used as Main for Two Fused Switches

Product Description

Eaton’s MEB switchgear is

a metal-enclosed assembly

of single high drawout VCP-W

vacuum circuit breakers and

control devices that are

integrated electrically for

circuit protection. (For

drawout vacuum breaker

metal-clad switchgear,

type VacClad-W, see Tab 23,

section 23.5.) 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.

Application Description

MEB can be applied as the

primary main device and

integrated with fused feeder

switches in a lineup of fused

MVS switchgear.

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.

MEB switchgear can also

be an economic benefit in

single-ended substations

because it may allow the

customer to eliminate the

secondary main protection

and switching device.

● Low resistance ground

schemes

● Single-ended substation

designs

● Overcurrent protection
