Merlin Gerin Multi 9 Ic 2000 P Manual ^new^ File

The Merlin Gerin Multi 9 IC 2000 P is a programmable twilight switch that combines light sensitivity with a time clock to control electrical loads based on both ambient brightness and specific schedules. Key Technical Specifications Brightness Range: Adjustable from 2 to 2000 lux.

Key characteristics (from historical specifications):

  • Series: Multi 9 (Modular 9mm per pole standard)
  • Type: Ic 2000 P – often an interface relay or auxiliary device
  • Function: Typically used for remote indication, control, or auxiliary switching for Merlin Gerin circuit breakers
  • Mounting: DIN rail (EN 50022)
  • Standards: Compliant with IEC/EN 60947 (low-voltage switchgear)

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.

Battery: The internal battery recharges automatically when power is connected. The Merlin Gerin Multi 9 IC 2000 P

The Merlin Gerin Multi 9 IC 2000 P is a high-performance twilight switch designed to manage lighting circuits based on ambient light levels. While Merlin Gerin has since been integrated into the Schneider Electric brand, these robust units remain a staple in many industrial and commercial electrical panels. Series: Multi 9 (Modular 9mm per pole standard)

Power Reserve: Features a lithium battery backup with approximately 6 years of autonomy.

Legacy Guides: An older application guide for the Merlin Gerin System is available on RS-online.com. ⚙️ Key Technical Specifications

  1. Wiring Configuration: The 4P version can be wired as “three-phase with neutral” or “single-phase with neutral protection.” The wrong wiring will cause nuisance tripping or, worse, fail to trip during a fault.
  2. Test Procedure: The manual specifies the required test cycle using the built-in “Test” button (usually marked “T”). For a 2000mA unit, the test resistor is higher than standard 30mA units. Using the wrong test procedure can damage the unit.
  3. Compatibility: The manual contains a compatibility matrix. The Ic 2000 P must be paired with upstream overcurrent protection (e.g., a Merlin Gerin C60N MCB) due to its low 3000A breaking capacity.

Built-in delay (approx. 40–80 seconds) for switching on and off to prevent "hunting" or flickering due to temporary light changes like car headlights or clouds.
