❓ Frequently Asked Questions

What is a direct rotary handle used for?

A direct rotary handle (Direct ROM) mounts straight onto the front of the MCCB and converts the toggle movement into a rotary action. It gives a comfortable, positive grip for switching and a clear ON / TRIP / OFF position indication, which is why most panel builders fit it on breaker doors and frequently operated feeders.

Does this handle support padlocking?

Yes. The rotary operating mechanism comes with a padlocking facility, so the breaker can be locked in the OFF position during maintenance – a standard safety requirement in most panels.

Which MCCBs does CM98040OOOO fit?

It is made for the DY250U1 frame and also fits DU250C and DU250 MCCBs of the same frame size, any pole count and any rating. With a rotary mechanism fitted, the MCCB’s front protection improves to IP54.
