Siemens ED63B110L - 110 A, 600 V, 3-Pole Circuit Breaker | AmpState

The Siemens ED63B110L is a robust 3-pole molded case circuit breaker engineered to protect your electrical system from overcurrent and short circuits. With a 110 A rating and a 600 V maximum, it is purpose-built for reliable branch circuit protection in panelboards and load centers across commercial, residential, and light industrial settings.

Why the ED63B110L stands out

• Compact molded case design maximizes valuable panel space, enabling efficient layouts and easier wire organization in tight enclosures.
• Thermal-magnetic trip unit delivers stable, repeatable protection by combining overload (thermal) and short-circuit (magnetic) sensing. This means predictable tripping behavior even as loads vary.
• OEM-focused compatibility designed to fit seamlessly with matching Siemens OEM load centers and panelboards, simplifying replacements and ensuring consistent protection coordination.
• Three-pole protection guards three-phase circuits, making it ideal for commercial equipment, HVAC systems, pumps, conveyors, and other 3-phase reliabilities.
