Siemens HED42B015L - 15 A, 480 V, 2-Pole Bolt-On Circuit Breaker | AmpState

The Siemens HED42B015L is a high‑reliability 15A, 480V, 2‑pole bolt‑on molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and load centers. Built for environments where vibration, continuity, and precise protection matter, this breaker provides solid performance for a range of commercial and light industrial applications.

• Secure bolt‑on mounting: a rigid connection to the bus bars minimizes movement and loosening in demanding installations, helping maintain consistent electrical contact over time.
• Thermal‑magnetic trip unit: combines thermal overload protection with magnetic short‑circuit protection, delivering stable, repeatable response to overcurrent events and fast clearing of dangerous faults.
• Two‑pole, 480V design: protects both conductors of 480V branch circuits, making it ideal for higher‑voltage distributions found in commercial spaces and light industrial environments.
• OEM‑grade compatibility: engineered to fit Siemens OEM load centers and panelboards, ensuring proper fit, electrical characteristics, and streamlined replacement in existing systems.
• Versatile applications: suitable for residential, commercial, and light industrial installations where robust 480V protection is required and reliable operation matters as much as safety.

Who benefits most: facilities managers, electrical engineers, and installers who need a durable, compatible breaker for Siemens‑equipped panelboards. Whether refreshing an aging service, upgrading a distribution panel, or configuring a dedicated 480V feed, the HED42B015L delivers predictable performance when it matters most.

Why this matters in real‑world use: a vibration‑resistant bus connection minimizes contact issues in mechanical spaces, while the thermal‑magnetic trip provides confidence that overloads are handled smoothly and short circuits are cleared quickly. This translates to reduced downtime, safer electrical systems, and easier maintenance over the life of your panel.

Practical tips for best results:

• Verify that your panelboard is compatible with bolt‑on, 2‑pole Siemens breakers and that the bus configuration matches the HED42B015L’s design.
• Follow the manufacturer’s torque recommendations during mounting to maintain the integrity of the bus connection.
• Use this 15A breaker on circuits where equipment and lighting demand controlled protection at 480V, ensuring the load does not exceed the rated amperage.
• For panel replacements, confirm the HED42B015L’s trip characteristics align with the system’s protection coordination and upstream protection schemes.

Engineered for reliability in demanding electrical environments, the Siemens HED42B015L offers precise, dependable protection for your 480V branches while integrating seamlessly with Siemens‑equipped panelboards. When you need a trusted, OEM‑grade solution for accurate overcurrent and short‑circuit protection, this bolt‑on breaker is built to perform.
