Siemens SND69100ANTH 69100A 3-Pole 600 V Circuit Breaker

Introducing the Siemens SND69100ANTH 69100A 3-Pole 600 V Circuit Breaker—a purpose-built overcurrent protector designed for demanding three‑phase power systems. This genuine Siemens device delivers reliable, consistent protection in commercial and industrial environments, helping you prevent faults before they disrupt operations.

Equipped with a 3‑pole configuration and a 600 V maximum rating, it interrupts all three phases uniformly when fault current occurs, preserving equipment and improving protection coordination within your distribution scheme. The part number SND69100ANTH (also referenced as 69100A) ensures you’re choosing an exact Siemens solution for compatibility with Siemens panels and standard enclosures.

Ideal use cases

Best suited for protecting large three‑phase circuits in commercial buildings, manufacturing facilities, data centers, and industrial equipment rooms. Use it as a main disconnect in a three‑phase service or as a branch‑circuit protector within Siemens‑based panelboards where coordinated protection with other Siemens devices is advantageous.

Practical guidance

Adopt a three‑pole protection strategy to ensure simultaneous disconnection of all phases during overloads or short circuits. When upgrading or replacing, verify mounting footprint and enclosure compatibility for a 3‑pole, 600 V device. Handle and store the breaker following standard electrical protection equipment practices to maintain long-term reliability and performance.
