Siemens 3VA4110 - 100A, 3-Pole, Circuit Breaker

Siemens 3VA4110 100A 3-Pole Circuit Breaker is built to safeguard three-phase electrical systems with dependable overcurrent protection. Designed for robust performance in demanding environments, this 3-pole unit is ready to integrate into standard distribution equipment and provides reliable protection for critical power flows in panels and MCCs.

Ideal for industrial, commercial, and OEM settings, the Siemens 3VA4110 helps keep equipment safe and available by quickly disconnecting faulty circuits and preventing damage from overloads. Its three-pole configuration delivers balanced protection across all three phases, reducing the risk of phase imbalances that can compromise motors, drives, and lighting systems.

Why this 3-Pole Circuit Breaker stands out

• 100A current rating: strong protection for moderate to heavy-load three-phase circuits common in manufacturing lines, HVAC systems, and power distribution racks.
• 3-Pole design: synchronized protection across all phases, essential for motor loads, contactors, and multi-circuit panels where balanced coordination matters.
• Versatile integration: compatible with panelboards, switchboards, and control panels in both new builds and retrofit projects, as well as motor control centers where space-efficient protection is required.
• Industrial reliability: engineered by Siemens for consistent performance in commercial and industrial environments, helping minimize downtime and maintenance concerns.

Use cases include protecting three-phase motors, drives, and distribution feeds in manufacturing lines, processing plants, and large facilities. It’s also well-suited for OEM assemblies that require a compact, reliable overcurrent protection device within standard Siemens-compatible architectures.

Practical considerations and tips:

• Plan protection around the full-load current and motor inrush so the 100A rating provides appropriate headroom without nuisance tripping.
• Integrate into existing Siemens distribution panels and MCCs to maintain system compatibility and simplify spare parts inventories.
• Pair with proper enclosure space and safe wiring practices to ensure easy maintenance access and clear labeling for rapid diagnostics.

Whether you’re upgrading an aging panel, stocking an OEM kit, or reinforcing a critical motor control center, the Siemens 3VA4110 100A 3-Pole Circuit Breaker delivers precise, dependable protection that keeps systems running smoothly and safely.
