11. Protection releases - References
The Tmax T8 circuit-breaker can be accessorized with PR232 - PR331 - PR332 protection releases.
The following modules are available: PR330/V-T8, PR330/D-M, PR330/R, BT030.
Details about the operation of the relays are given in the following documents:

11.1 Safety notes
WARNING
: this symbol highlights information about operations, actions or circumstances that can cause injuries to the personnel,
damage to the unit or economic losses.
Read this manual, the specifi c manuals of the electronic releases and the getting started manuals carefully and fully.
This device must only be used by qualifi ed and expert personnel.
Ifb there are doubts about whether it can be used safely, the unit must be put out of service to prevent it from being used accidentally.
You must assume that the device is not safe to use if:
1. The unit shows visible signs of damage.
2. The unit does not function (e.g. with autotest or with the trip test unit).
3. The unit has been damaged during transport.
The circuit-breaker must be open before any servicing or replacements are made.
Also remember to disconnect any power supplies connected.
11.1.1. Notes for dielectric strength tests
it is forbidden to perform dielectric strength tests on the inputs and outputs of the releases.
