6. Line Circuit Breaker

The selection of the correct line circuit breaker depends on various factors. For

detailed information for the rating of a line circuit breaker, please refer to section

6.4.3 "The Line Circuit Breaker" (Page 44).

No loads should be connected to this

power circuit!

A circuit breaker's load disconnecting properties can be utilized to disconnect the

inverter from the grid under load.

A screw fuse element, e.g. D system (Diazed) or D0 system (Neozed) has no load

disconnecting properties, and thus may be used as cable protection, but not as a

load disconnection device.

Upon disconnection under load, the fuse element may be destroyed, or its

functionality may be inhibited by contact burning.
