Siemens QP3100 - 100A, 240VAC, 3-Pole, Circuit Breaker

Introducing the Siemens QP3100 — a robust 100A, 240VAC, 3-pole circuit breaker designed for demanding electrical systems. Built to deliver dependable overcurrent protection in distribution panels, motor control centers, and control panels, this unit keeps industrial and commercial installations safe and reliable.

Key advantages of the QP3100:

• Three-pole protection for balanced, simultaneous interruption across all phases in three-phase systems, reducing the risk of phase imbalance and equipment damage.
• 100A current rating at up to 240VAC to handle high-load feeders and circuit protections.
• Versatile mounting for panelboards, switchboards, and control panels — adaptable to a wide range of enclosures in industrial settings.
• Reliable protection for OEM equipment — designed to integrate into custom electrical assemblies with consistent performance.

Who benefits most:

• Electrical engineers and maintenance teams designing or upgrading panelboards and MCCs.
• OEM manufacturers seeking trusted, durable protection devices for three-phase equipment.
• Facilities engineers managing commercial or light industrial distribution networks that demand strict overcurrent protection.

Why choose this Siemens breaker over other options?

• Dedicated three-phase coordination with a compact, standardized form factor that simplifies distribution panel layouts.
• Global Siemens reliability backed by decades of protection technology and consistent performance in challenging environments.
• Clear protection boundaries with precise current and voltage ratings, aiding proper selectivity and safe operation.

Practical usage tips:

• Coordinate with upstream protective devices to ensure selective tripping and minimize downtime during faults.
• Verify the panelboard or MCC enclosure supports 3-pole breakers and the 3-phase bus configuration.
• In maintenance windows, test the breaker’s trip and reset functionality to confirm reliable operation when it matters most.
