The Series GT miniature circuit breakers have a calibration temperature of 40°C. This differentiates them from the other Series G (30°C).
Within this series the GT10 has a smaller short circuit capacity than the GT25.
Following add-on devices can be delivered with these products: Auxiliary contacts, undervoltage release (Tele U), shunt trip (Tele L), motor operator (Tele Mp) and panel board switch (PBS).
Accessories are available for the MCB's within our Series GT.
See below the main features for this range.
