Siemens | HGG3B100L | Circuit Breaker | 100A | 3-Pole | 600V

Siemens HGG3B100L is a 100A, 3-pole circuit breaker designed for reliable protection in 600V distribution systems. Built for maintenance, retrofit, and replacement tasks where exact specifications matter, this unit provides a clear path to safe, compliant power delivery in demanding electrical environments.

Why this matters in real-world use

In three-phase installations, a 3-pole breaker ensures simultaneous disconnection of all live conductors, reducing arc potential and improving overall safety during fault conditions. The HGG3B100L is purpose-built for applications where precise amperage, number of poles, and voltage rating must align with existing equipment and codes.

• Amperage: 100 A
• Poles: 3-Pole
• Voltage rating: 600 V
• Best compatibility reference: Confirm fit and ratings using the part number HGG3B100L before ordering

Ideal use scenarios

• Maintenance and service work on 3-phase, 600V distribution panels where a direct replacement is required
• Retrofits to upgrade or standardize protection across existing Siemens enclosures
• Replacement of a failed breaker in industrial or commercial facilities that rely on robust, documented compatibility

Practical guidance for purchasing and installation

• Always verify the panel model, bus configuration, and existing protection scheme to ensure a seamless replacement
• Use the HGG3B100L part number as the primary reference to confirm compatibility with your Siemens components
• If undertaking a retrofit, check for any required accessories or mounting kits that ensure proper fit within your enclosure
