Introduction In the world of industrial and commercial electrical distribution, few names command as much respect as Merlin Gerin , now a core brand within the Schneider Electric ecosystem. Among their most legendary product lines is the Multi 9 range, known for its robustness, modularity, and cutting-edge (for its time) protection technology.
If the original PDF proves impossible to locate, remember: the critical parameters (4P, 2000mA, 3000A Icn, electromechanical AC type) are sufficient for a competent electrician to install it safely. However, for full compliance and safety, Merlin Gerin Multi 9 Ic 2000 P Manual
One specific model that continues to generate significant interest—and many search queries—is the . Whether you are a maintenance electrician, a plant facilities manager, or a collector of vintage high-quality electrical gear, finding an original manual for this device is critical for safe operation and compliance.

A: Merlin Gerin was a French company. The original English manual is a short translation. You can find the bilingual PDF by searching “Merlin Gerin Multi 9 Ic 2000 P Notice d’instruction” – often the second half is English.
A: The manual allows it as a “load break switch” (rated for making and breaking load current up to 80A). However, it does not provide short-circuit protection. You must have a fuse or MCB upstream.
| 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. | A Note on Obsolescence The Multi 9 Ic 2000 P uses an electromechanical trip mechanism that degrades over time. The manual specifies a 15-year operational lifespan . If your unit is older than that (most are, as production ceased in the early 2000s), it is time to replace it with a modern equivalent: Schneider Electric A9N17954 (iID 4P 63A 2000mA). Part 6: Frequently Asked Questions (FAQ) Q1: Can I use the Multi 9 Ic 2000 P for human protection? A: No. The manual clearly states this unit is for “protection of equipment and fire prevention.” For people, you need a 30mA RCD.
