Siemens ED63B070L - 70 A, 600 V, 3-Pole Circuit Breaker | AmpState

Siemens ED63B070L is a 70A, 600V, 3-pole molded case circuit breaker designed to provide dependable branch-circuit overcurrent and short-circuit protection in panelboards and loadcenters. This compact device is built to simplify distribution setup while delivering solid protection for a range of building types.

The thermal-magnetic trip unit offers stable, repeatable protection by addressing both overload conditions and sudden short circuits. This means fewer nuisance trips in normal operation and reliable interruption when fault conditions arise, helping protect wiring, equipment, and personnel without compromising system uptime.

Its compact molded-case design maximizes panel space, making it easier to fit into crowded panels and align with other protection devices. The ED63B070L is explicitly designed for compatibility with matching Siemens OEM loadcenters and panelboards, enabling quick swaps, consistent trip characteristics, and coordinated protection across the entire distribution system.

• Ideal for three-phase distribution in commercial or light industrial settings, providing unified protection for multi-conductor circuits.
• Thermal-magnetic protection: Combines overload sensing with fast short-circuit interruption for reliable circuit safety.
• Space-efficient molded case: Keeps panel layouts compact and organized, freeing up room for additional devices or wiring runs.
• OEM-compatible: Seamless integration with Siemens panelboards and loadcenters for straightforward replacement and consistent performance.
• Versatile application range: Suitable for residential, commercial, and light industrial electrical distributions that require robust branch-circuit protection.
