• Poles: 3-Pole
• Voltage: 600 V
• Mounting: Bolt-On
• Part Number: NGB3K080B

This circuit breaker serves as vital overcurrent protection for electrical distribution circuits in industrial and commercial settings. Its 3-pole configuration provides balanced protection across three phases, making it suitable for applications that require coordinated trip and stable performance in 600V systems. Where to use: - Maintenance, retrofit, or replacement in Siemens bolt-on panelboards and switchgear that specify the NGB family - Environments demanding durable, panel-compatible protection for multi-phase electrical distribution Compatibility and installation notes: - Confirm fit and ratings before ordering; the part number is the best reference for compatibility - Ensure the panel model and bus configuration match the NGB3K080B’s mounting and electrical requirements - Bolt-On mounting requires access to the panel interior and adherence to proper safety procedures during installation Why choose this Siemens breaker: - Precise 80A, 3-pole protection within a 600V class device designed for Siemens bolt-on panels - Streamlined retrofit and replacement workflow thanks to the exact NGB family alignment - Clear, part-number-based compatibility reduces guesswork in complex electrical environments Practical use cases: - Upgrading an aging distribution panel to restore balanced, three-phase protection for motors, compressors, and other loads - Replacing a mismatched breaker in a Siemens-equipped system to restore full protection without reconfiguring the panel - Specifying a ready-to-install bolt-on solution for service upgrades in new or existing installations that operate at up to 600V This description highlights how the Siemens NGB3K080B combines specific electrical ratings with a bolt-on mounting approach to meet the demands of professional maintenance, retrofit, and replacement projects. It’s a focused, compatible choice for engineers and electricians working within Siemens-equipped electrical distributions.
