Eaton CHLO – Frequently Asked Questions
1) Does the Eaton CHLO handle lockdog let me padlock a breaker off for lockout/tagout?
No. The CHLO handle lockdog holds a CH-series breaker handle in the on or off position, but it is not a padlockable device. If your LOTO procedure requires a padlock hasp on the breaker handle, this accessory will not satisfy it. Use it where you need the handle mechanically held in position rather than locked with a keyed or combination padlock.
2) Will the CHLO lockdog fit any breaker, or only Eaton CH breakers?
It is a CH-series accessory. The CHLO is built to secure the handle of Eaton CH-series circuit breakers in CH loadcenters and panelboards. It is not a universal handle lockoff, so breakers of another Eaton type or another manufacturer are outside what it is made for.
3) Does installing an Eaton handle lockdog take up space in the panel?
Yes, plan for it. The CHLO requires one additional pole space on the loadcenter or panelboard beyond the breaker it secures. On a panel that is already full, you need a free pole next to the target breaker before this will go in.
4) What is the amperage and interrupting rating on the Eaton CHLO handle lockoff?
The CHLO carries a 225 A rating with a 10 kAIC interrupting rating, which matches CH loadcenter and panelboard applications at that level. Confirm your panel's bus rating does not exceed 225 A before specifying it.
5) Can I use this Eaton lockdog in a three-phase panel?
Yes. The CHLO is configured for three-phase CH loadcenter and breaker systems, and it is intended for equipment in a NEMA 1 enclosure, which is the general-purpose indoor rating. For outdoor or washdown locations, a NEMA 1 panel is the wrong enclosure and this accessory is specified to that environment.
6) Can a handle lockdog keep a breaker from being switched off accidentally?
That is one of its two uses. The CHLO secures the handle in either the on or the off position, so it works for holding a critical circuit on (fire alarm, refrigeration, life safety feeders) as well as for keeping a de-energized circuit from being restored. Because it is not padlockable, it is a deterrent against casual operation rather than a lockable safety device.
7) What is the Eaton part number for the CH handle lockdog, and what is it made of?
Order it as Eaton CHLO. The accessory uses aluminum construction with an aluminum bus for electrical continuity.
