Product description

The Siemens B340H00S01 40A 3P 240V Shunt Trip circuit breaker is engineered for dependable protection in panelboards, load centers, and electrical distribution setups. With a robust 3-pole design and a 240V operating voltage, this breaker is purpose-built for 3-phase systems where reliable fault isolation and controlled shutoffs matter.
Shunt-trip functionality is the standout feature, enabling remote disconnection when safety or control signals require an immediate, safe interruption of power. This is invaluable for maintenance windows, automated safety interlocks, and building management scenarios where a quick, centralized shutdown protects personnel and equipment without a manual stand‑by sequence.

- Direct part-number match for Siemens panelboards and distribution gear, streamlining replacements and reducing downtime during service calls.
- Three-pole protection designed to reliably interrupt all conductors in a 3-phase circuit, ensuring consistent protection across industrial and commercial systems.
- Remote shutoff capability via shunt-trip, enabling safe, centralized control in emergency and maintenance workflows.
- Availability from AmpState means you can source this specific part quickly for projects, repairs, or spare inventory.
