Square D NC26S - Circuit Breaker | AmpState

The Square D NC26S molded case circuit breaker is a compact, dependable solution for branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Built by a trusted electrical systems manufacturer, this NC26S unit combines space-saving design with precise protection to keep electrical systems safe, compliant, and reliably powered.

• Compact molded-case design optimizes panel space, allowing more efficient layouts in crowded panels and reducing enclosure footprint without sacrificing protection.
• Thermal-magnetic trip unit delivers stable, repeatable protection across a wide range of temperatures and load conditions, with a fast magnetic trip for short-circuit events and a thermal element for gradual overloads.
• OEM-compatible performance designed to work with matching Square D OEM loadcenters and panelboards, ensuring proper fit, consistent trip characteristics, and straightforward replacement.
• Versatile application suitable for residential, commercial, and light industrial circuits, making it a practical choice for a variety of panel configurations and protection needs.

Technical snapshot

• Manufacturer: Square D
• Part Number: NC26S
• Type: Thermal-magnetic molded case circuit breaker
• Application: Branch circuit overcurrent and short-circuit protection

The NC26S excels in scenarios where reliable protection must be paired with space efficiency. Use it to protect branch circuits in residential panels, commercial lighting and outlet circuits, or light industrial equipment feeders. Its compatibility with Square D panelboards and loadcenters means you can upgrade or replace aging breakers with confidence, maintain consistent trip curves, and keep labeling and documentation aligned with the rest of the system.

In practice, you’ll appreciate how the thermal-magnetic mechanism balances sensitivity and selectivity: the magnetic element snaps in quickly to clear short circuits, while the thermal element provides steady protection against sustained overloads—reducing nuisance trips and helping protect both wiring and connected equipment. For electricians, facility managers, and homeowners upgrading electrical protection, the Square D NC26S offers a thoughtful, integrated solution that aligns with existing Square D infrastructure and performance expectations.
