Siemens HEB3B080B - 80 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Siemens HEB3B080B is a rugged, 3-pole bolt-on molded case circuit breaker rated at 80A and 600V. Designed to deliver dependable branch circuit overcurrent and short-circuit protection, it fits seamlessly into panelboards and load centers, making upgrades, maintenance, or new builds smoother and safer.

Why this breaker stands out

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection. In cabinets and crowded panels where vibration or movement is common, this design helps maintain consistent electrical contact and reduces arcing risk over time.
• Thermal-magnetic trip unit combines reliable thermal overload protection with an instantaneous magnetic trip for short circuits. The result is stable, repeatable protection performance across varying temperatures and fault conditions.
• OEM compatibility is engineered to work with matching Siemens load centers and panelboards, ensuring straightforward substitution or upgrade without custom modifications.
• Versatile, three-phase protection—the 3-pole configuration safeguards all three phases in typical commercial and light industrial systems, helping prevent unbalanced loads and equipment damage.

Ideal applications

• Residential, commercial, and light industrial panelboards and load centers where reliable branch-circuit protection is essential.
• New installations or panel upgrades in offices, retail spaces, schools, HVAC rooms, lighting systems, and small manufacturing environments.
• Replacement or retrofit in Siemens OEM panelboards to maintain system compatibility and performance.
