Merlin Gerin | IN1000 | Circuit Breaker | 1000A | 3-Pole | 690V

Meet the Merlin Gerin IN1000 3-Pole Circuit Breaker, a high-current solution built for demanding industrial electrical systems. With a 1000 A rating and a 690 V capacity, this unit protects three-phase feeders in switchgear, motor control centers, and main distribution panels. When you’re performing maintenance, retrofitting older gear, or replacing a failed breaker, the IN1000 delivers precise specifications and reliable protection that your equipment depends on.

Why choose the IN1000? It combines the trusted Merlin Gerin lineage with exact electrical ratings, ensuring consistent trip performance across all three poles. That means fewer nuisance trips and coordinated protection for motors, transformers, and distribution circuits in high-load environments.

Key capabilities

• Current rating: 1000 A
• Configuration: 3-Pole
• Voltage rating: 690 V
• Application: ideal for maintenance, retrofit, and replacement where exact specs are required
• Reference: Part number IN1000 is the primary compatibility reference

Practical use cases

• Replacing a failed breaker in a 3-phase, 690V distribution panel servicing heavy equipment or process lines
• Upgrading older switchgear during facility modernization to accommodate higher fault currents
• Serving as a reliable main or feeder protective device in industrial MCCs and substations

Installation and compatibility tips

Before ordering, confirm fit and ratings against your panel or switchgear. The IN1000 part number is the most reliable reference for compatibility, reducing guesswork and ensuring a smooth swap with minimal downtime. If your system uses a Merlin Gerin or Schneider Electric MCCB footprint, this unit is designed to align with existing bus configurations and termination options.

Why this matters in the field

In high-current environments, dependable protection is non-negotiable. The Merlin Gerin IN1000 provides a robust, time-tested solution for 3-phase 690V networks, helping you minimize downtime, safeguard valuable equipment, and maintain safe operation across shifts. By offering a clear retrofit or replacement path, you can plan maintenance with confidence and keep critical processes running smoothly.
