Type A

Residual current transformer

  • Main features

    • For residual current detection in 3/4-phase alternating current networks
    • Highly sensitive current sensor for detecting even the smallest fault currents
    • Simple connection via 4-pin spring-loaded terminal
    • High safety thanks to integrated overvoltage protection
    • Flexible use due to a wide frequency range
    • Transformation ratio: 600/1
    • Max. primary residual current in A: 18
    • Max. wire diameter in mm: 4 x approx. 8 (rm-10 qmm) or 8 x 5,5 (rm-6 qmm)
    • Round conductor in mm: 20
