Merlin Gerin Multi 9 Ic 2000 P Manual
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).
Product Type: Industrial Control Relay / Interface Relay
Brand: Merlin Gerin (now part of Schneider Electric)
Series: Multi 9
Model: IC2000 P
Schneider Electric maintains an extensive archive of legacy product documentation.
Steps:
Pro Tip: Schneider sometimes archives legacy docs under the old reference numbers. Try searching for the full reference number (printed on the side of your device, e.g., "A9C12345" — though exact numbers vary). Merlin Gerin Multi 9 Ic 2000 P Manual
Important Note: Many users confuse the "Ic 2000 P" with main circuit breakers. If your device has a rotary handle or push-buttons and low-current contacts, it is likely an auxiliary or control unit, not a power breaker. Always verify by consulting the manual—which is exactly why you need it.
In the world of industrial electrical distribution and circuit protection, few names command as much respect as Merlin Gerin. Now a core brand within the Schneider Electric ecosystem, Merlin Gerin has produced some of the most reliable and innovative circuit breakers and protection devices for decades. Among their celebrated product lines is the Multi 9 series, known for its modularity, high performance, and compliance with international standards (IEC/EN 60898).
One specific device that continues to generate technical inquiries, particularly from maintenance engineers, facility managers, and electrical contractors, is the Merlin Gerin Multi 9 Ic 2000 P.
If you have landed on this article, you are likely searching for one critical thing: the official manual for the Multi 9 Ic 2000 P. Whether you need installation instructions, wiring diagrams, technical specifications, or troubleshooting steps, you have come to the right place. The Multi 9 Ic 2000 P uses an
In this article, we will cover:
Let’s begin by demystifying the product itself.
Because this unit is obsolete, replacement is often recommended over repair. However, the manual lists these common scenarios:
| Symptom | Likely Cause (from manual) | Solution | | :--- | :--- | :--- | | The test button does not trip the device | 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. | Product Type: Industrial Control Relay / Interface Relay
Once you locate the official Merlin Gerin Multi 9 Ic 2000 P manual, do not let it get lost again.
Attempting to install, wire, or diagnose a Merlin Gerin Multi 9 Ic 2000 P without the original manual poses serious risks:
In short: the manual is not a suggestion—it is a legal and operational requirement.
