Overview

The VML01 rccb 63a 30ma detects earth leakage and disconnects the circuit before harm occurs,
helping prevent electric shock and fire hazards caused by insulation faults. It is available in 2-pole and 4-pole
versions for single-phase and three-phase boards and is suitable for housing, tertiary, and light-industrial use.

Key Features

  • Poles: 2P / 4P
  • Rated current (In): 16, 25, 32, 40, 63, 80, 100 A
  • Rated sensitivity (IΔn): 10 / 30 / 100 / 300 mA
  • Rated voltage (Ue): 240 V~ (2P) / 415 V~ (4P)
  • Insulation voltage (Ui): 500 V | Frequency: 50/60 Hz
  • Residual making & breaking (IΔm): 500 / 630 / 800 / 1000 A (per In group)
  • Conditional short-circuit (Inc = IΔc): 6000 A / 10000 A (with upstream SCPD)
  • Impulse withstand (Uimp): 6 kV
  • Dielectric test: 2.5 kV for 1 min (power frequency)
  • Terminal protection: IP20
  • Terminal capacity (cable): 25–35 mm²
  • Tightening torque: 2.5 N·m
  • Environmental limits: −25 °C … +55 °C (ambient); −40 °C … +70 °C (storage)
