Siemens HED41B015L - 15 A, 277 V, 1-Pole Bolt-On Circuit Breaker | AmpState

Meet the Siemens HED41B015L, a 15A, 277V, 1-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. From AmpState, this unit is built to withstand the demands of residential, commercial, and light industrial panels, providing a secure, reliable safeguard for essential circuits.

• Bolt-on mounting for a secure, vibration-resistant bus connection. The robust bolt-on design minimizes movement and connection issues in panels, promoting consistent protection even in environments with vibration.
• Thermal-magnetic trip unit for stable, repeatable protection. This combination trip mechanism reacts quickly to overcurrent events while minimizing nuisance trips, keeping critical loads protected without unnecessary interruptions.
• 277V, 1-pole configuration. Ideal for branch circuits in commercial lighting, small equipment feeds, or other 277-volt applications where single-pole protection is appropriate.
• Compatibility with matching OEM load centers and panelboards. Engineered to fit Siemens panel ecosystems, ensuring proper fit and performance without adapters.
• Versatile across sectors. Suitable for residential spaces, commercial offices, retail environments, and light industrial settings where reliable overcurrent protection matters.
