Siemens ED42B070L - 70 A, 480 V, 2-Pole Circuit Breaker | AmpState

Siemens ED42B070L is a 2-pole molded case circuit breaker rated at 70 A and 480 V, engineered for dependable branch-circuit overcurrent and short-circuit protection in panelboards and load centers. Built to integrate with Siemens OEM equipment, it delivers reliable protection across residential, commercial, and light industrial applications, especially where 480 V distribution is involved.

Why this ED42B070L stands out

• Compact molded-case design maximizes panel-space efficiency, letting you fit more circuits without crowding the enclosure.
• Thermal-magnetic trip unit provides stable, repeatable protection by quickly responding to overloads and short circuits with predictable tripping behavior.
• 2-pole configuration for 480 V systems ensures simultaneous disconnect of both hot conductors, enhancing safety and simplifying coordination in multi-conductor circuits.
• OEM compatibility designed to drop into matching Siemens panelboards and load centers, reducing installation risk and ensuring electrical characteristics align with upstream equipment.
• Versatile application ideal for commercial and light-industrial electrical rooms, machine control panels, service panels, and other 480 V distribution needs.
