Siemens NGG3B035 - 35 A, 600 V, 3-Pole Circuit Breaker | AmpState

Siemens NGG3B035 is a 35A, 600V, 3-pole molded-case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers.

Why this breaker stands out

• Compact molded-case design preserves valuable panel space, making it easier to fit additional circuits in crowded panels without compromising protection.
• Thermal-magnetic trip unit provides stable, repeatable protection. The thermal element handles gradual overloads, while the magnetic element quickly responds to short circuits, helping to minimize damage and downtime.
• 3-pole configuration delivers balanced, three-phase protection, reducing arcing risk and ensuring coordinated interruption across all phases when a fault occurs.
• OEM-compatible performance is engineered to pair seamlessly with matching Siemens OEM load centers and panelboards, promoting reliable operation and straightforward replacement.
• Versatile for multiple environments—suitable for residential, commercial, and light industrial applications where dependable, code-compliant protection is essential.

Ideal use cases

Install the NGG3B035 in distribution panels for lighting and receptacle circuits, HVAC equipment feeds, small motors, and other branch circuits that demand dependable protection. It’s particularly advantageous when upgrading or expanding an existing Siemens panel where a precise 3-pole, 35A, 600V MCCB ensures consistent trip characteristics and a clean, orderly panel layout.
