Hello Paul, first, I want to ask you to open a Service request in the future for such questions: www.siemens.com/support-request In general, it is the responsibility of the operator to decide how to handle the circuit breaker. The background of your question is probably that maintenance work on the downstream switchgear must ensure that no dangerous voltage is allowed to pass through the feeder breaker. I would recommend using the locking device in accordance with EN 60204-1, for example. This ensures that it is not possible to reconnect either remotely or at the breaker itself. However, no work may/can be carried out on the circuit-breaker itself. For maintenance work on the breaker itself, it should always be moved to the disconnected position if possible and removed from the withdrawable frame. Enclosed is a page from the current LV10 catalog... https://support.industry.siemens.com/cs/ww/en/view/109750636 ...with the possible order numbers for the above-mentioned locking device for slide-in switches.
