Siemens HEB2B020B - 20 A, 600 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Siemens HEB2B020B — a 20A, 600V, 2-pole bolt-on molded case circuit breaker designed to deliver reliable branch circuit protection in panelboards and load centers. Built for environments where vibration is a factor, this breaker’s bolt-on mounting provides a rigid, secure bus connection that stays put through use and maintenance cycles.

Key differentiators that matter in real-world setups

• Secure bolt-on mounting: Ensures a tight, vibration-resistant connection to the bus, reducing the chance of loosening over time and maintaining consistent protection on demanding installations.
• Thermal-magnetic trip unit: Delivers stable, repeatable protection by combining precise thermal sensing with magnetic tripping for fast response to short-circuit events.
• Compatibility with OEM load centers: Designed to integrate smoothly with matching Siemens OEM panelboards and load centers, simplifying selection and replacement in existing systems.
• Versatile protection for diverse settings: Suitable for residential, commercial, and light industrial applications where reliable overcurrent and short-circuit protection is essential.

What it protects and how it helps you plan

• Protects branch circuits from overcurrent and short-circuit conditions on both hot lines with 2-pole operation.
• Ideal for standard 20A circuits in panelboards and load centers, including lighting, receptacle, and small equipment circuits in homes and small-to-medium commercial spaces.
• Part of a coordinated protection strategy when paired with matching Siemens panel products, helping you maintain consistent trip characteristics across your electrical distribution.
