Siemens | SJD69400H | Circuit Breaker | 400A | 3-Pole | 600V

Siemens SJD69400H Circuit Breaker is a robust 400A, 3-Pole, 600V protection device designed for demanding electrical environments. Built to handle maintenance, retrofit, and replacement tasks where exact specifications matter, this breaker helps keep critical power feeds safe and reliable.

Key benefits include precise compatibility with Siemens panels and a straightforward fit when the part number SJD69400H matches your equipment. Before ordering, confirm fit and ratings; the part number is the best reference for compatibility.

• Amperage: 400A
• Poles: 3-Pole
• Voltage: 600V
• Primary use: maintenance, retrofit, and replacement in 3-phase, 600V systems

Why this matters for your operation:

• Three-phase protection: A 3-Pole design ensures simultaneous disconnection of all live conductors in a three-phase circuit, improving safety and equipment protection.
• Reliability by design: Siemens build quality supports consistent performance in panel boards, switchgear, and industrial controls.
• Streamlined retrofits: When replacing an older unit with matching specs, using the SJD69400H helps minimize downtime and compatibility issues.

Ideal use scenarios:

• Upgrading or maintaining commercial/industrial panels that run on 400A loads
• Replacing a failed circuit breaker in a Siemens-based enclosure
• Retrofits where a precise 600V, 3-Pole, 400A specification is required

Notes: Always verify fit and ratings before ordering. The part number SJD69400H is the most reliable reference for compatibility, ensuring you’re selecting the correct unit for your system.
