With a frame capacity of 125AF, the 125 Series offers three main types: the 125-EK, the 125-SK, and the 125-HK. The 125-EK and 125-HK are available in 2 and 3 poles, respectively, while the 125-SK offers 4 poles. The choice of poles allows for flexible configuration according to specific needs and requirements.

The 125 Series is designed to operate within a rated insulation voltage (Ui) of 690V, ensuring safe and efficient electrical performance. The rated voltage (Ue) is 600V, making it compatible with a wide range of electrical systems and applications.

The 125 Series provides various options for rated current (In), including 15A, 20A, 30A, 40A, 50A, 60A, 75A, 100A, and 125A. This versatility allows users to select the appropriate current rating based on their specific load demands.

For rated breaking capacity (kA), the 125 Series exhibits different values depending on the voltage level. At 220V, the 125-EK has a rating of 35/18kA, the 125-SK has a rating of 50/25kA, and the 125-HK offers 85/35kA. At 380V, the ratings are 25/13kA for the 125-EK, 30/15kA for the 125-SK, and 50/20kA for the 125-HK. These breaking capacities ensure reliable protection against overloads and short circuits.
