Bender LINETRAXX RCM420 Type A Residual Current and Ground Fault Monitor
₨ 0
The Bender LINETRAXX® RCM420 is a Type A AC and pulsed DC sensitive residual current monitor designed for earthed power supply systems (TN and TT systems) where continuous insulation monitoring is required. It evaluates fault and residual currents to trigger alarms early, preventing unexpected system shutdowns and critical equipment damage.
Key Specifications & Technical Overview
- Application Environment: Earth fault monitoring in single- or three-phase AC distribution setups, and specific single-conductor monitoring (e.g., PE, N-PE, and PE-PAS connections).
- Response Range (\(I_{\Delta n}\)): Fully adjustable pickup values ranging from 10 mA to 10 A.
- Frequency Range: Captures electrical faults across a wide bandwidth from 42 to 2,000 Hz.
- Standard Compliance: Built and tested in full compliance with IEC 62020 for residual current monitors.
- Measurement Type: Displays highly accurate, true r.m.s. value measurements directly on-screen.
