Square D | Q2L3175 | Circuit Breaker | 175A | 3-Pole | 240V | Feed-Through

Meet the Square D Q2L3175 circuit breaker—a robust, practical solution for industrial and commercial panels that demand dependable protection with straightforward retrofit options. With a 175 Amp rating, 3 poles, and a 240-volt feed-through design, this unit is built to handle demanding feeder configurations while preserving existing wiring layouts.

Key specifications:

• Model: Q2L3175
• Amperage: 175 A
• Poles: 3-Pole
• Voltage: 240 V
• Design: Feed-Through

Why choose the Q2L3175? It’s not just a breaker—it's a precise compatibility solution for panels designed around the Square D Q2L family. The feed-through configuration simplifies downstream feeder connections, reducing wiring clutter and enabling smoother future expansions. When replacing a unit, relying on the exact part number ensures you keep electrical ratings aligned with the panel’s engineering, minimizing downtime and avoiding compatibility issues.

Ideal use cases include:

• Maintenance replacements in existing Square D panelboards requiring 175 A, 3-Pole, 240 V feed-through protection.
• Retrofit projects that add or reconfigure feeder-through circuits without changing the panel bus or overall architecture.
• New installations that demand an OEM-grade breaker with a clear compatibility reference.

Practical considerations and tips:

• Always confirm fit and ratings before ordering. The Q2L3175 model is the best reference for compatibility with panels designed for feed-through breakers in the Square D lineup.
• Check the panel labeling and service requirements to ensure 240 V operation and proper grounding alongside the 3-pole protection path.
• During installation, ensure downstream feeders are rated for the expected load to safeguard against nuisance trips and ensure reliable distribution.
