ST31245GPG 125A 3P 240V Safety Switch | AmpState

ST31245GPG is a 125 A, 3-pole, 240 V safety switch purpose-built for equipment disconnect and isolation at the point of use. This device is a practical choice for retrofit projects and maintenance planning, offering a consistent part number to simplify stocking and replacements when uptime is critical.

Why this safety switch matters

In industrial environments, reliable isolation is essential for safe servicing. The 3-pole design ensures all conductors on a 3-phase circuit can be disconnected, reducing the risk of accidental energization during maintenance. With a 125 A rating and 240 V operation, it suits a wide range of mid-range machinery and equipment commonly found on manufacturing floors, processing lines, and large-value systems.

• Full three-phase isolation: Disconnects all live lines to prevent exposure during service work.
• 125 A, 3P, 240 V configuration: Aligns with typical industrial power setups for dependable performance.
• Retrofit-friendly: Maintains a consistent part number in your maintenance catalogs, aiding planning and reorder accuracy.
• AmpState availability: Purchase through AmpState with support to verify fit and compatibility.

Ideal use cases

• Retrofit installations where you want to preserve existing part-numbering for quick procurement and minimal change management.
• Maintenance shutdowns on 3-phase equipment that requires safe, verifiable isolation at the point of use.
• Industrial environments with mid-range machinery, conveyors, or process equipment operating on 240 V three-phase power.

What sets ST31245GPG apart

Beyond basic disconnect functionality, this safety switch is designed with maintenance workflows in mind. Its compatibility with existing part-number schemes helps facilities avoid catalog fragmentation, reducing downtime when replacements are needed. AmpState not only carries the part but also offers assistance to confirm compatibility and fit, ensuring you don’t buy the wrong switch for your system.

Practical guidance for deployment

• Plan around your facility’s lockout/tagout procedures to maximize worker safety during servicing.
• Coordinate with your electrical team to verify the enclosure footprint and mounting method aligns with existing panels or switchgear.
• Use AmpState’s compatibility support to confirm the ST31245GPG will fit your specific equipment and wiring configuration before purchase.
