Square D Q13100 - 100A, 3-Pole, Circuit Breaker

Introducing the Square D Q13100 — a rugged 100A, 3-pole circuit breaker designed for demanding electrical environments. Built by Square D, a trusted name in electrical protection, this unit delivers reliable overcurrent protection for 3-phase systems in panelboards, switchboards, and control panels.

With a 3-pole design, it provides true three-phase protection from a single device. The common-trip mechanism ensures all three phases disconnect simultaneously during a fault, reducing the risk of phase imbalance and equipment damage.

• Current rating: 100 A
• Poles: 3-Pole (three-phase)
• Breaker type: Circuit Breaker
• Best suited for: panelboards, switchboards, and control panels in industrial, commercial, and OEM applications
• Protection focus: dependable overcurrent protection for distribution panels and motor control centers

Ideal use cases include guarding 3-phase feeders for heavy motors on manufacturing lines, powering compressors and conveyors in industrial facilities, or supporting air handling and drive systems in commercial buildings. In every scenario, this 100A Square D breaker helps prevent unexpected downtime by interrupting fault currents quickly and safely.

Why choose this 3-pole Square D breaker over smaller or single-phase options? It delivers synchronized protection across all three phases, simplifies wiring by consolidating three circuits into one device, and aligns with standard Square D panel and MCC architectures for straightforward installation and maintenance.

Tips for selection and installation: verify your panel accepts 3-Pole 100A devices, follow manufacturer torque guidelines and local electrical codes, and ensure proper labeling and safety clearances in the distribution panel or motor control center. For OEM builders, this unit offers a compact, reliable solution that supports scalable three-phase distribution while maintaining service continuity in critical facilities.
