Siemens HEB3B100B - 100 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Siemens HEB3B100B is a 3-pole bolt-on molded case circuit breaker rated at 100 A and 600 V, engineered to deliver dependable branch circuit overcurrent and short-circuit protection within panelboards and loadcenters. Built for steady performance in real-world electrical environments, this unit combines robust construction with precise protection technology to keep power running smoothly.

• Bolt-on mounting: provides a secure, vibration-resistant bus connection that stays aligned through panel motion and vibration, reducing the risk of loose connections and intermittent trips.
• Thermal-magnetic trip unit: delivers stable, repeatable protection by combining thermal overload sensing with magnetic fast-trip response for short-circuit events.
• Three-pole design: ideal for three-phase circuits common in commercial and light industrial installations, enabling coordinated protection across all phases.
• OEM panel compatibility: designed to integrate seamlessly with matching Siemens OEM load centers and panelboards for straightforward installation and reliable performance.
• Versatile applications: suitable for residential improvements, commercial electrical rooms, and light industrial distributions where dependable protection is essential.

Use cases include protecting feeders and branch circuits in service panels, distribution panels, and subpanels where consistent trip behavior and durable mounting are critical. The HEB3B100B is a practical choice when upgrading or expanding electrical distributions that require a proven, three-pole solution with strong mechanical integrity and precise protective action.
