FAQ
Questions Buyers Ask
Why choose MBO over the MES or CA body?
MBO is the long life Euro style body with reinforced terminals, aimed at boards that sit at full load continuously and at panel builders who want a black component that matches the rest of the board.
Which frames exist?
MBO-62/B, MBO-62/20, MBO-62/30, MBO-62/40, MBO-30, MBO-40, MBO-60, MBO-70 and MBO-100.
Is a sealable cover available?
MBO has a built in hinged terminal cover. Where lead sealing and a name plate window are required, use the ABO high accuracy body.
