Product description
Shipping
Meet the Siemens SJD69400GH, a robust 400A, 3-Pole circuit breaker built for demanding 3-phase systems. Engineered by Siemens, this unit is designed for maintenance, retrofit, and replacement scenarios where exact spec matching is essential, helping you protect critical equipment and keep facilities running smoothly.
- Amperage: 400A
- Poles: 3-Pole
- Voltage: 600V
- Reference compatibility: Part number SJD69400GH serves as the best reference for fit and compatibility
- Ideal use cases: maintenance, retrofit, and replacement in three-phase, 600V systems
Why this Siemens breaker stands out
Designed to deliver reliable protection in industrial and commercial environments, the SJD69400GH pairs precise 400-amp protection with a solid three-pole configuration. Its 600-volt rating makes it suitable for high-demand machinery, HVAC systems, and other equipment that rely on stable, three-phase power. Because it’s a Siemens part, you gain predictable trip performance and seamless integration with compatible panels and protective devices.
Smart ways to use this breaker
- Replacing a failed 3-Pole, 600V breaker in an existing panel to restore line protection for a 3-phase circuit
- Retrofit projects where upgrading to modern, compatible Siemens protection is required
- Stocking a spare for critical facilities that depend on uninterrupted power to essential loads
Compatibility and installation notes
To ensure a flawless fit, verify the exact panel and current rating before ordering. The SJD69400GH part number is the strongest reference for compatibility, so cross-check it against your panel label or service documentation. When replacing, follow standard safety procedures for circuit work, and confirm that the system voltage and three-phase configuration match the 600V, 3-Pole specifications.
Practical guidance for best results
- Keep a spare 400A, 3-Pole, 600V breaker on hand for critical infrastructure—tiresome downtime is costly when a single component fails
- Document the replacement with the exact part number (SJD69400GH) to simplify future maintenance or audits
- Use in environments that require robust protection for high-current loads while maintaining reliable trip behavior and trip time characteristics
