SANHE-EI41 needs to be installed in the automatic switch of the distribution curcuit, and is connected with the three-phase circuit inside the automatic switch to monitor the grounding signal for necessary protection. When numerical signal and phase exceeds the standard range, this transformer will cooperate with the automatic switch to implement protection actions to prevent danger happening.

1. EI41 vertical bobbin and pins with frame for connection terminals
2. Using oriented silicon steel sheet as the core
3. Lead wires of different colors distinguish different signals and polarities, and connect with the designated position inside the automatic switch
1. The accurate various electrical parameters can respond in time to abnormal voltage values and phase deviations
2. Solid structure, stable and reliable performance, suitable for long-term use under harsh conditions
3. Materials of the oriented silicon steel sheet with moderate characteristics is more cost-effective
