Siemens SHND69120ANTH - 1200 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Siemens SHND69120ANTH is a high-capacity, bolt-on molded case circuit breaker engineered to protect large branch circuits with precision in panelboards and loadcenters. With a 1200A rating and 600V maximum, this 3-pole device is built for demanding commercial and light industrial environments, while still being suitable for certain residential applications that require robust, industrial-grade protection.

What sets it apart

• : a rigid connection to the bus bars minimizes vibration-induced looseness and ensures dependable current sharing across the distribution system.
• : combines overload protection with fast magnetic trip for short circuits, delivering stable, repeatable protection performance even under variable load conditions.
• : designed to work with matching Siemens OEM loadcenters and panelboards for streamlined replacement and consistent protection coordination.
• : 1200A rating supports substantial feeder and motor circuits without compromising protection accuracy or speed.
• : suitable for residential, commercial, and light industrial installations where reliable branch-circuit protection and panelboard integrity are essential.

Why this breaker matters for your electrical system

In any distribution panel, protecting conductors and equipment from overcurrent and short circuits is critical. The SHND69120ANTH delivers a decisive combination of robustness and precision. The bolt-on design provides a secure, vibration-resistant bond to the bus, which is especially valuable in environments with equipment vibration, temperature fluctuations, or frequent door operations that might otherwise loosen a less secure connection. The thermal-magnetic trip unit responds predictably to overloads and short circuits, reducing nuisance trips while delivering swift isolation when faults occur.
