Hi Guys,
Nice video but I am mising the end: switching on the cirquit breaker...
How do you arm the SACE Tmax XT4 circuit breaker?
Pushing down and up again doesn't work
Must be missing a simple detail but I can't push the handle into the upwards on position anymore.
Mounting a coil trip unit went in a breathe...

“Hi, thanks for contacting us. It is possible that you have mounted a UVR accessory. The UVR aims to open the circuit-breaker when the release is subject to a power failure or a voltage drop. As prescribed in the standards, the opening is guaranteed when the voltage is between 70% to 35% Un. After tripping, the circuit-breaker can be closed again if the voltage exceeds 85% Un. So when the UVR is mounted, the only way to close the breaker is to power supply the UVR.”

@@ABBElectrification Thank you for your fast response here!
Regretfully the XT4 cannot be (dis)armed and armed again, even without the coil inserted.
Is there a way to release the lever (it is blocked and ca't be moved in the downwards position)?
Is there a special procedure needed before inserting the trip coil other then arming and pushing the reset button to get the lever in the neutral position?

@@offgridd In this case an investigation may be required to better understand the problem. In order to manage this specific unit, you should contact the seller or directly the local ABB support new.abb.com/contact-centers
