Miniature Circuit Breakers: Series G
The Series G miniature circuit breakers are covering a complete range of short circuit breaking capacities and tripping characteristics.
Our MCB’s within the Series G can be delivered with add-on devices:
Auxiliary contacts, undervoltage release (Tele U), shunt trip (Tele L), motor operator (Tele Mp) and panel board switch (PBS) (exception: G20).
Accessories are available for the MCB’s within our Series G, except for the G20.
The S-types are especially meant for shipping applications (G60 S and G100 S).
See below the main features for this range
