Product description
The SSRK-2 to SSRK-6 current summing transformers are specifically designed for use with split-core current transformers (CTs). They enable the summing of 2 to 6 currents in the secondary circuit of low-power current transformers. Their compact design and high accuracy (Class 0.5) make these transformers ideal for energy measurement in low-voltage networks. The low burden of just 0.2 VA is specifically tailored to the low output power of split-core current transformers.
