Great devices! Purchased a XT4 with thermal and electromagnetic trip unit, installed the shunt trip coil and closed the case.
All neatly explained, kudo's!
Maybe kind of stupid question: How do I arm (switch on) this XT4 unit?
Getting it in the test mode: no problem.
The XT4 unit doesn't allow me to arm it however.
Should I remove a safety/transport component first to arm the unit?
Looking out to installing this device to protect my 48V 200A solar batteries if anything in the system goes wrong but I can't find the documentation how to commission this breaker...
Any help or tips are highly appreciated!
This breaker plastic parts are extremely fragile and mechanically unreliable. A brand new XT2 63A breaker just fell apart. On/Off handle snapped with bare hand, auxiliary contacts bracket broke off and there is no reliable position indication. I expect at least some quality from device which costs 700 Eur.
