❓ Frequently Asked Questions

What is the difference between a direct and an extended rotary handle?

A direct ROM mounts on the breaker itself. An extended ROM (Extended Rotary Handle) adds a shaft and a door-mounted operating knob, so you can switch the MCCB from outside the panel without opening the enclosure door. It keeps operators away from live parts and is the standard choice for panel doors and MCC 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.

Which MCCBs does EM90970OOOO fit?

It is made for the DY125U frame (16A to 125A models, any pole count). With a rotary mechanism fitted, the MCCB’s front protection improves to IP54.
