Siemens HEG3B025 Circuit Breaker, 25A, 3-Pole, 600V

Engineered by Siemens for demanding industrial environments, the HEG3B025 Circuit Breaker delivers reliable overcurrent protection for three‑phase power systems up to 600V. With a 25A rating and three poles, it ensures simultaneous disconnection of all conductors, enhancing safety and protecting motors, drives, and feeders in manufacturing floors, control panels, and distribution boards.

Designed for service, maintenance, and replacement projects, this part is the right fit for Siemens-based installations where precise part‑number matching matters. To ensure compatibility, verify fit by part number HEG3B025 and align it with your application requirements to maintain correct protection and trip characteristics.

Key benefits

• Three-pole protection provides complete phase isolation in 3-phase systems, simplifying safe maintenance and reducing risk during servicing.
• 25A rating targets moderate-load circuits and motor feeds, helping prevent nuisance trips while safeguarding conductors and equipment.
• 600V maximum operating voltage suits typical industrial distribution and control circuits found in factories and facilities.
• Reliable Siemens build supports long service life in harsh environments and simplifies spare-part sourcing for ongoing maintenance programs.
• Direct applicability for replacements in compatible Siemens panels, helping minimize downtime during upgrades or part failures.
