Siemens | NGB1B035B | Circuit Breaker | 35A | 1-Pole | 347V | Bolt-On

Meet the Siemens NGB1B035B, a purpose-built circuit breaker engineered for 347V systems that demand precise, reliable protection. With a 35-amp rating and a 1-pole design, this bolt-on unit is tailor-made for streamlined installation in compatible Siemens panels, making maintenance, retrofit, and replacement projects quicker and cleaner.

Key advantages that set this breaker apart:

• Exact compatibility: Part number NGB1B035B serves as the definitive reference for fit, ensuring you’re selecting a device that matches your panel’s architecture and trip characteristics.
• Fast, secure bolt-on mounting: A robust bolt-on design minimizes field wiring complexity and reduces installation time, while delivering a solid, vibration-resistant connection.
• Targeted protection: 35A rating protects circuits that draw significant load without nuisance trips, while the 1-pole configuration is ideal for single-phase loads within 347V distribution schemes.
• Voltage suitability: Rated for 347V, aligning with commercial/industrial systems that use 347V line-to-neutral or line-to-line configurations while maintaining safe interrupting capacity.
• Reliability you can trust: Built on Siemens’ engineering standards, delivering consistent performance across installations and service intervals.

Common use cases include replacing a failed breaker in 347V service panels, retrofitting older equipment to modern protection standards, or performing targeted maintenance on critical circuits where precise ampacity matters.

How to ensure you’re selecting correctly: Always verify the exact fit with your panel model and confirm the ratings match your system requirements. The NGB1B035B is the most reliable reference for compatibility in Siemens bolt-on applications.

In short, the Siemens NGB1B035B is not just a component—it's a carefully chosen solution for safeguarding 347V circuits with confidence, efficiency, and durability. Ideal for electrical technicians, facility managers, and installers upgrading commercial or industrial distributions.
