Siemens NGG2B015 - 15 A, 600 V, 2-Pole Circuit Breaker | AmpState

The Siemens NGG2B015 is a dependable, compact 2-pole molded case circuit breaker designed to protect branch circuits in panelboards and load centers. With a 15A rating and a 600V maximum, it provides precise, reliable overcurrent and short-circuit protection where it matters most, delivering peace of mind for both new installations and upgrades.

Key features that stand out

• Space-efficient design — a compact molded case profile that helps you maximize panel space without compromising protection.
• Thermal-magnetic trip unit — combines a precise thermal element for overload protection with a magnetic element for fast, repeatable short-circuit tripping your circuits can count on.
• OEM-ready compatibility — engineered to pair with matching Siemens OEM load centers and panelboards for streamlined, worry-free installation.
• Versatile applications — ideal for residential, commercial, and light industrial environments where dependable branch circuit protection is essential.

Why this model matters

The NGG2B015 isn’t just a switch. It’s a thoughtfully designed protective device that helps prevent electrical damage and downtime. The 2-pole design is perfect for 240V circuits, ensuring both hot legs trip together, which minimizes the risk of arc faults and equipment damage. Its robust construction and proven Siemens reliability translate into fewer nuisance trips and more consistent performance in demanding panelboard scenarios.
