Complete Guide: Merlin Gerin Multi 9 IC2000 P Manual – Specs, Wiring, and Troubleshooting

Product Type: Industrial Control Relay / Interface Relay
Brand: Merlin Gerin (now part of Schneider Electric)
Series: Multi 9
Model: IC2000 P

Q1: Is the Merlin Gerin Multi 9 Ic 2000 P a circuit breaker?

A: No. Most likely it is an auxiliary contact or control relay. A standard Merlin Gerin circuit breaker would have a thermal-magnetic trip curve (e.g., C, D, or B curve). The "Ic" designation stands for Interface and Control.

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.

Q2: My manual is in French. Where is the English version? 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.

Q3: Can I use this as a main switch? 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.

Q4: I lost the terminal shield. Is it required? A: Per the manual’s safety section, the terminal finger protection (shroud) is mandatory for IP20 compliance. Do not operate without it.

Final Verdict: Keep It or Replace It?

If you find a working IC2000 P in an existing panel, it is a robust, reliable unit. However, if it trips or fails the test button, do not search eBay for a used one. The modern equivalent is the Schneider Electric Acti9 iID (e.g., A9R41263).

Why replace? Newer RCDs have:

Better immunity to nuisance tripping from surges.
Higher short-circuit withstand (Icn).
Easier busbar connections.

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).

8. Safety Reminder

Always de-energize the panel before handling or replacing the relay.
Do not exceed 6 A resistive or 4 A inductive load.
Ensure proper creepage and clearance distances – the Multi 9 range is rated for basic insulation only.

High Power Loads: While it can directly control loads up to 1000W, use a contactor for higher power requirements or inductive loads to protect the internal relay.

In the heart of a bustling industrial complex, where the hum of machinery was the symphony of progress, there stood a modest electrical cabinet. Within its steel confines, amidst a maze of wires and components, resided the Merlin Gerin Multi 9 Ic 2000 P. It was not merely a circuit breaker; it was a silent guardian, a sentinel of safety.

The Ic 2000 P had been installed years ago, its sleek, grey casing a testament to the engineering prowess of Merlin Gerin. Its purpose was clear: to protect the delicate electronic systems of the facility from the ravages of overloads and short circuits. It was a role it embraced with unwavering dedication.

Day and night, the Ic 2000 P monitored the flow of electricity. It was a constant vigilance, a tireless watch against the unseen forces that could disrupt the factory's rhythm. The manual, a weathered document tucked away in a nearby folder, was its guiding light, containing the secrets of its operation and the wisdom of its creators.

One sweltering afternoon, a sudden surge of power rippled through the electrical grid. It was a formidable force, a digital tempest that threatened to overwhelm the factory's systems. The Ic 2000 P felt the surge, its internal sensors reacting with lightning speed. Within milliseconds, it tripped, its mechanical heart snapping shut, severing the path of the destructive current.

The factory fell silent. The hum of machinery was replaced by an eerie stillness. But in that silence, there was safety. The Ic 2000 P had fulfilled its duty, preventing a potentially catastrophic event.

The facility's electricians, guided by the manual, soon arrived at the cabinet. They examined the tripped breaker, its indicator window a clear sign of its heroic intervention. With careful hands, they reset the Ic 2000 P, restoring power to the factory.

The machines roared back to life, their symphony resumed. The Ic 2000 P returned to its silent watch, its grey casing a symbol of reliability and protection. It was a modest component, but its story was one of unwavering commitment to safety, a story told in the quiet corners of the industrial world.
