Siemens B32000S01 20A 3P 240V Circuit Breaker, Shunt Trip | AmpState

The Siemens B32000S01 is a dependable 3-pole circuit breaker built to protect circuits in panelboards, load centers, and electrical distribution systems. With a 20 A rating and a 240 V operating voltage, it’s designed to handle everyday electrical loads with trusted Siemens performance. The integrated shunt trip capability adds a crucial safety layer by enabling remote, rapid shutdown when an external signal is received, helping you meet safety protocols and emergency response requirements.

• Amperage & voltage: 20 A, 3 poles, 240 V
• Shunt Trip: external remote-tripping capability for fast, safe de-energization
• Application: ideal for panelboards, load centers, and electrical distribution panels
• Retrofit-friendly: designed to preserve your existing part-number ecosystem, simplifying maintenance planning and stock management
• Availability: part number B32000S01, available from AmpState

Why this matters in real-world setups: facilities with strict inventory requirements benefit from keeping the exact part number during retrofits and replacements, ensuring compatibility with existing enclosures and protection schemes. The shunt trip feature is particularly valuable in safety-conscious environments—remote tripping can coordinate with building management systems, automation, or external safety controls to minimize risk during maintenance or emergencies.

Who benefits most: electrical contractors, facilities engineers, and maintenance teams responsible for commercial or light-industrial distribution networks who need reliable protection with precise part-number continuity and straightforward retrofitting.

Use cases include:

• Replacing worn or outdated breakers in existing 3P/240V panels without altering panel configurations
• Retrofitting safety controls that require a remote trip signal for emergency shutdowns
• Maintaining stock consistency in service fleets where a specific Siemens part number is mandated
• Planning maintenance and part spares around a known, standardized component for quicker service calls
