Siemens | HGB2K035B | Circuit Breaker | 2-Pole | 480V

Siemens HGB2K035B is a rugged 2-pole circuit breaker crafted for 480V systems, purpose-built for maintenance, retrofit, and replacement tasks. When you need a dependable, plug-and-play solution, this part number is the best reference for compatibility, helping you avoid costly downtime from mismatches.

Why this 2-Pole 480V breaker stands out

Two-pole protection means simultaneous disconnection of both conductors, delivering safer, more reliable shutdown in high-voltage circuits. The HGB2K035B is designed to fit into compatible Siemens-equipped panels and select third-party enclosures, making it a practical choice for service technicians and facility engineers alike.

• Precise fit for 480V applications — engineered to operate reliably in high-voltage environments, protecting circuits and equipment from overloads and short circuits.
• Maintenance, retrofit, and replacement ready — ideal when upgrading aging gear, restoring interrupted service, or stocking a dependable spare for critical panels.
• Part number as your compatibility anchor — HGB2K035B is the most reliable reference to verify fit and ratings with your panel or equipment documentation.
• Compact, practical design — built to integrate into existing 2-pole configurations without excessive panel modification, helping you minimize downtime during replacements.

Use cases and who benefits

This breaker is well-suited for environments where 480V circuits demand robust protection and quick maintenance access. Ideal for:

• Industrial control panels undergoing routine maintenance or phased retrofits
• Replacement of aging or worn breakers in 480V electrical systems
• Spare parts strategy for facilities with Siemens-heavy electrical infrastructure
• Upgrade projects that require a precise 2-pole, 480V solution with clear compatibility references

Practical guidance for compatibility and installation

To ensure seamless operation, verify these points before ordering or installing:

• Confirm the exact part reference — use HGB2K035B as the primary compatibility check with your panel label, schematics, or equipment documentation.
• Match voltage and pole configuration — ensure your system is designed for 480V and uses a 2-pole protective device.
• Check panel compatibility — while designed for Siemens panels, confirm the breaker will physically and electrically interface with your enclosure and bus arrangement.
• Review ratings and safety requirements — verify the protective characteristics align with your circuit’s operating conditions and follow all local electrical codes during installation.

Installation and safety notes

Handle with care and adhere to standard electrical safety practices. Disconnect power, use appropriate PPE, and follow your facility’s lockout/tagout procedures. If the existing installation relies on a specific Siemens model family, referencing the HGB2K035B part number will help ensure you’re selecting a direct, safe replacement.

Why choose Siemens for high-voltage protection

Siemens combines decades of engineering excellence with a focus on reliable performance in demanding environments. The HGB2K035B embodies this approach by delivering predictable trip behavior, robust construction, and a clear compatibility reference that simplifies procurement and maintenance workflows. When uptime matters, selecting the exact, documented part number reduces guesswork and supports efficient service operations.
