Siemens ED63B080 - 80 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Siemens ED63B080 is a sturdy 80A, 600V, 3‑pole bolt-on molded case circuit breaker designed to shield branch circuits in panelboards and load centers with precision and reliability. Built for environments where vibration and temperature changes are part of daily operation, this unit delivers predictable protection you can count on.

• Secure bolt-on mounting delivers a rigid, vibration‑resistant bus connection, helping to maintain consistent electrical contacts and reduce drift over time.
• Thermal‑magnetic trip unit provides stable, repeatable protection: the thermal element handles gradual overloads while the magnetic element responds quickly to short circuits for fast fault clearance.
• OEM-compatible design is engineered to pair with matching OEM load centers and panelboards, ensuring proper fit, alignment, and coordinated protection across the system.
• Versatile for multiple facilities ideal for residential, commercial, and light industrial applications where dependable overcurrent and short‑circuit protection is essential.
• Three-pole configuration supports three‑phase circuits, simplifying installation in broader electrical systems and minimizing component count.

Use cases: Install or upgrade panelboards and load centers that require robust branch‑circuit protection with a secure mounting solution. Replace aging or undersized breakers in three‑phase service panels, or implement in new builds where a reliable bolt‑on MCCB (molded‑case circuit breaker) simplifies wiring and maintenance.

Why this matters: With the ED63B080, you gain precise protection curves and fast fault clearance that help prevent damage to downstream equipment, reduce nuisance trips under fluctuating loads, and keep critical circuits—like lighting, HVAC, and motors—operating smoothly. The combination of bolt‑on stability and a thermal‑magnetic trip mechanism delivers a dependable, long‑term solution for panelboard and loadcenter protection.
