Merlin Gerin Multi 9 Ic 2000 P Manual Updated (2024)
Use the rotary dial on the front of the unit to set the light level at which the circuit should activate.
| Symptom | Likely Cause (from manual) | Solution | | :--- | :--- | :--- | | | Mechanical failure or welded contacts. | Immediate replacement. Do not use. | | Nuisance tripping (randomly trips) | Cumulative earth leakage exceeds 2000mA due to old insulation or moisture. | Use a clamp meter to measure leakage. Reduce load or replace cables. | | Device trips under heavy load but not when idle | Overheating of internal solenoid due to loose terminal connections. | Torque terminals to 2.5 Nm. Check for burn marks. | | Physical damage (cracked housing) | Arc flash or over-torqued screws. | Replace with modern Schneider Electric iID RCCB 2000mA. | Merlin Gerin Multi 9 Ic 2000 P Manual
The Merlin Gerin Multi 9 IC 2000 P is a part of the Multi 9 range of protection devices, designed to offer a wide range of protection functions for electrical circuits. This device is particularly notable for its modular design, making it highly adaptable to various applications and easily expandable as per system requirements. The IC 2000 P model is equipped with advanced features for circuit protection, including overcurrent, short circuit, and earth leakage protection, among others. Use the rotary dial on the front of
| Symptom | Likely Cause (per manual) | Solution | | :--- | :--- | :--- | | | Cumulative earth leakage > 30mA. | Use a clamp meter to find leaky appliance (heater, motor, old wiring). | | Test button fails to trip | Mechanical seizure or welded contacts. | Critical: Replace the unit. Do not rely on it. | | Lever won't reset | Persistent earth fault or internal damage. | Disconnect downstream wires. If lever resets, fault is in wiring. If not, RCD is dead. | | Unit runs hot | Loose terminal screws or overcurrent. | Torque to spec (2 Nm). Remember, this RCD has no thermal overload protection (needs an MCB in series). | Do not use
Possibly, but you must check the manual’s compatibility section. Acti 9 (the successor to Multi 9) may require a different mechanical adapter. When in doubt, use current Schneider auxiliary blocks (e.g., A9A26924).
