Block Brand: Block

The Block STE 230V to 24V Transformers are low inrush current control, safety, or isolation current transformers with CAGE-CLAMP connection terminals. Designed with a very good switch-on behaviour thanks to reduced starting currents, plus high performance for the volume thanks to compact design, this high quality tranfsormers also has excellent corrosion protection and low noise thanks to BLOCKIMPEX vacuum impregnation.

  • Contact protected screw connection terminals - comply with UVV BGV A3
  • Simple mounting - robust metal footplate with oval slots
