Siemens ED23B070 - 70 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the Siemens ED23B070 — a 70 A, 240 V, 3-pole bolt-on molded case circuit breaker crafted for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. This isn’t a generic safety device; it’s a purpose-built solution designed to keep critical electrical systems safe and running smoothly.

• Bolt-on mounting for a rigid, vibration-resistant bus connection. The bolt-on design delivers a secure, low-impedance link that stays solid under vibration or maintenance cycles, reducing the risk of loose connections and intermittent trips.
• Thermal-magnetic trip unit for stable protection. Combines a thermal element for overload detection with a magnetic mechanism for fast response to short circuits, delivering repeatable protection performance you can count on.
• 3-pole, 70 A at 240 V configuration. Ideal for three-phase systems or multi-wire applications common in commercial and light industrial settings, providing comprehensive protection across all conductors.
• OEM-compatible for seamless installations. Designed to pair with matching Siemens OEM load centers and panelboards, ensuring reliable fit, electrical integrity, and straightforward retrofits or new builds.
• Versatile for multiple environments. Suitable for residential-adjacent commercial spaces, small offices, light manufacturing, and service panels where dependable overcurrent and short-circuit protection matters most.

In practice, the ED23B070 delivers predictable, long-lasting performance when protecting feeders and branch circuits. Its compliant design with a robust bus connection minimizes contact resistance and heat buildup, while the thermal-magnetic trip unit minimizes nuisance trips and ensures quick isolation of faults—keeping both wiring and equipment safer and downtime to a minimum.

Why choose this Siemens breaker? Because it pairs rugged, vibration-resistant mounting with precise, reliable protection suited for panelboards and load centers where space is at a premium and performance matters. If you’re upgrading an electrical distribution system or installing a new panel, the ED23B070 offers a practical, compatible, and dependable solution that aligns with Siemens’ engineering standards and your real-world needs.
