Siemens HED41B020 20A 1P 277V Circuit Breaker | AmpState

The Siemens HED41B020 20A 1P 277V circuit breaker delivers reliable overcurrent protection for panelboards, load centers, and electrical distribution systems in commercial environments. This exact part number is ideal for retrofit work and maintenance planning where consistency matters, helping you source compatible replacements quickly without guessing about fit.

Why this breaker matters for 277V circuits

• 1 Pole, 20 A, 277V: Protects single-circuit branches in commercial wiring where 277V mitigation is standard, preventing overloads and reducing the risk of equipment damage.
• Designed for panelboards and load centers: A trusted choice for reliable distribution protection in service entrances, switchgear interfaces, and mid- to large-scale electrical layouts.
• Part-number stability for retrofits: Using HED41B020 keeps replacement stock consistent across projects, simplifying maintenance planning and future servicing.

Practical use cases

• Retrofits in office buildings or retail environments where existing 277V circuits are common, ensuring seamless compatibility with existing panels.
• Scheduled maintenance programs that rely on fixed part numbers to minimize downtime and procurement delays.
• New installations in commercial spaces where a proven 277V, single-pole protection device is required by design engineers.
