Square D KAR36175 175A 3-Pole 600 V Circuit Breaker

Meet the Square D KAR36175 circuit breaker—a rugged, high-capacity protection device built for demanding 3‑phase systems. With a 175 A current rating and a 600 V maximum operating voltage, this 3‑pole breaker is designed to safeguard large motors, feeders, and other heavy loads in commercial and light industrial environments. Part number KAR36175, this unit joins the Square D lineage you trust for reliable electrical protection.

• Current rating: 175 A
• Poles: 3
• Voltage rating: 600 V
• Part number: KAR36175

Why this model stands out for 3‑phase protection: it provides robust overcurrent protection for large three‑phase circuits, helping prevent damage to motors, compressors, and distribution feeders. The 600 V rating makes it suitable for mid‑voltage applications common in commercial buildings and light industrial setups, while the 3‑pole configuration ensures balanced protection across all phases.

Ideal use cases include:

• Protecting large motors and three‑phase equipment in manufacturing and processing facilities
• Feeding 3‑phase HVAC, compressors, and cooling systems in commercial spaces
• Group protection for main distribution panels where high-current, three‑phase protection is required

Practical considerations for buyers: ensure your panel is compatible with KAR‑series breakers and that the 175 A rating aligns with the protective requirements of the circuit and wire sizes you’re using. Replace like-for-like with the same part number in compatible Square D panels to maintain electrical safety and panel labeling accuracy. This KAR36175 is a dependable choice for professionals who prioritize reliability and consistent performance in demanding electrical systems.
