Siemens ED43M070 70A 3-Pole 480 V Circuit Breaker delivers reliable, three-phase protection for industrial electrical systems. Engineered by Siemens, this 70-amp breaker with a 3-pole configuration is designed to intercept faults in 480 V distribution networks, safeguarding motors, drives, and power circuits from overloads and short circuits. Why this breaker stands out
- Precise three-pole protection: The 3-pole design guarantees simultaneous disconnection of all live conductors, minimizing remaining fault paths and helping prevent equipment damage.
- Optimized for 480 V industrial environments: With a 480 V rating, it fits standard industrial power distribution layouts where three-phase equipment—motors, pumps, conveyors, and HVAC gear—depends on dependable overcurrent protection.
- Clear part identification: Part Number ED43M070 makes replacement and cross‑referencing straightforward in spare parts inventories and maintenance workflows.
- Built for durability and consistency: Siemens engineering brings consistent trip performance and long-term reliability, reducing nuisance trips and downtime in demanding applications. Key specifications at a glance
