Siemens HED41B035L - 35 A, 277 V, 1-Pole Bolt-On Circuit Breaker | AmpState

Siemens HED41B035L is a 35A, 277V, 1-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Built for durable performance in real-world installations, it combines robust mounting with precise protection technology to keep critical circuits safe.

• Secure bolt-on mounting: A rigid, vibration-resistant bus connection reduces movement and wear, improving long-term reliability in environments with vibration, temperature changes, or equipment start-ups.
• Thermal-magnetic trip unit: This dual-action protection blends thermal overload sensing with fast magnetic response to short circuits, delivering stable, repeatable protection without nuisance trips.
• OEM compatibility: Designed to drop into matching Siemens panelboards and load centers, simplifying replacements, upgrades, and service compatibility without panel mods.
• Versatile application: Ideal for residential, commercial, and light industrial settings where 277V circuits power lighting, runners, and small equipment fleets.

• Amperage rating: 35A
• Voltage rating: 277V
• Number of poles: 1
• Mounting style: Bolt-on
• Type: Thermal-magnetic molded case circuit breaker
• Application: Branch circuit overcurrent protection and short-circuit protection

Use cases include safeguarding 277V lighting feeders, small commercial subpanels, and control circuits in office complexes or light industrial environments. When upgrading from older devices or pairing with Siemens OEM panels, the HED41B035L provides a straightforward, reliable path to compliant, code-ready protection.

Why this matters: in spaces where 277V circuits are common, reliable protection minimizes downtime and equipment damage. The bolt-on design reduces bus movement during service, and the thermal-magnetic trip ensures fast, predictable responses to overloads and faults, helping you maintain continuous operation with fewer interruptions.

Practical tip: verify your panel’s compatibility with a 1-pole, bolt-on 35A breaker and ensure the surrounding enclosure is rated for 277V environments. This breaker is purpose-built to work with Siemens load centers and panelboards, delivering seamless performance as part of a cohesive protection scheme.
