Siemens Q28000S01 800A 2P 240V Circuit Breaker, Shunt Trip | AmpState

Siemens Q28000S01 800A 2P 240V Circuit Breaker with Shunt Trip, now available from AmpState, is engineered for reliable circuit protection in panelboards, load centers, and electrical distribution systems. Built to endure demanding environments, this breaker delivers strong performance where safety and uptime matter most.

Key features that set this unit apart include its high-ampacity design, precise two-pole operation, and the integrated shunt trip capability. The shunt trip enables remote or automatic disconnection on signal, providing an essential layer of safety for critical equipment, building automation, and maintenance shutdowns without requiring manual intervention at the panel.

• 800 A current rating – robust protection for heavy-load feeders and essential circuits.
• 2-pole configuration – ensures simultaneous disconnection of both live conductors for enhanced safety and coordinated protection.
• Shunt Trip – enables remote or automated tripping, improving control during maintenance, emergencies, or demand-response scenarios.
• 240 V operation – compatible with standard distribution networks commonly found in commercial and industrial installations.
• Part number consistency – the Q28000S01 designation supports retrofit projects where maintaining a specific catalog number simplifies replacements and service documentation.
• OEM reliability – Siemens engineering and manufacturing quality provide predictable performance and long-term availability.

This breaker is the right choice for projects where retrofit or maintenance planning requires a familiar, consistent part number while delivering uncompromising protection for critical loads. It’s particularly well-suited for upgrading or replacing aging protective devices in existing panelboards and load centers without reconfiguring the system architecture.
