Split core current transformer KBR
- Current transformers
Split core current transformers of the KBR series for primary nominal currents from 50 A up to 1000 A are ideal for subsequent installation into existing systems. The special “click” system enables a “one-handed” quick installation .
The KBR transformers are available with secondary current of 5 A / 1 A, as current sensor (0…333 mV) or as transformer (4…20 mA DC) and come in three different sizes.
