Merlin Gerin | IN250 | Circuit Breaker | 250A | 3-Pole | 690V

When your industrial power network demands dependable, three-phase protection, the Merlin Gerin IN250 delivers. This 3-pole circuit breaker is engineered for high-current service with a 250A rating and a 690V maximum system voltage, making it a practical choice for demanding maintenance, retrofit, or replacement projects where exact specifications matter.

Key specifications

• Amperage: 250A
• Poles: 3-Pole
• Voltage: 690V
• Part number reference: IN250

Why this matters: a 3-pole design ensures simultaneous disconnection of all three phases, reducing arc risk and providing balanced protection for three-phase loads in industrial environments. The 690V rating aligns with typical European and many global industrial power systems, enabling safer, more controlled shutdowns during faults or maintenance.

Why choose the IN250 for your panel

The Merlin Gerin IN250 is built for durability in demanding settings, offering consistent interruption performance in networks that require robust overcurrent protection. Its specification alignment (250A, 3-Pole, 690V) supports reliable protection for motors, transformers, and other high-power equipment commonly found in manufacturing floors, data centers, and large commercial facilities.

Ideal use cases

• Maintenance and retrofit projects where you need a direct, exact-spec replacement for aging equipment
• Upgrading distribution boards that service three-phase machinery with up to 250A load
• New installations in systems operating at or below 690V with three-phase power

Compatibility and ordering notes

• Best reference for compatibility: use the part number IN250 to verify fit with your panel or switchgear
• Important: confirm fit and ratings against your specific equipment before ordering

For professionals seeking a reliable, industry-standard solution for three-phase protection at 690V, the Merlin Gerin IN250 combines precise electrical specs with a heritage of trusted performance. Use it where precision and consistency matter—then count on it to perform when it matters most.
