Siemens B34000S01 40A 3P 240V Circuit Breaker, Shunt Trip | AmpState

Siemens B34000S01 is a 40A, 3-pole, 240V circuit breaker with a shunt trip accessory, engineered for dependable circuit protection in panelboards, load centers, and broader electrical distribution systems. This unit is the smart choice for technicians who need a direct part-number match that fits precise specifications.

Key features that matter in the field:

• Amperage and voltage: 40 A at 240V, suitable for safeguarding feeders and critical circuits within commercial and industrial panels.
• Three-pole design: Provides balanced protection across three conductors, ensuring comprehensive shutdown on fault conditions.
• Shunt trip capability: Enables remote disconnection—integrate with safety interlocks, building automation, or emergency shutdown schemes to enhance crew protection and incident response times.
• Direct part-number match: Ideal for panel builders and service teams who prioritize exact compatibility to minimize installation time and stock complexity.
• Reliable Siemens construction: Built to meet standard electrical distribution requirements and provide consistent performance in demanding environments.

Why this breaker stands out

In busy maintenance settings or spare inventory programs, having a specific part like B34000S01 reduces guesswork and retrofit risk. The integrated shunt trip adds an extra layer of safety by enabling rapid, remote control of circuit isolation during emergencies or control-system events. Its 3P 240V configuration is a common fit for many panelboards and distribution panels, making it a practical choice for both new installations and replacements.

Ideal use cases

• Panelboards and load centers requiring remote trip capability for safety interlocks or emergency shutdowns
• Service inventories where exact Siemens part numbers are mandated for efficient maintenance and turnover
• Industrial or commercial electrical distributions with three-phase circuits that demand reliable protection
