Square D KAL361101042 110A 3-Pole 600 V Circuit Breaker

Introducing the Square D KAL361101042 110A 3-Pole 600 V Circuit Breaker—a purpose-built protection device engineered for reliable performance in three-phase electrical systems. With a 110-amp current rating, three poles, and a 600-volt rating, this breaker is designed to safeguard feeders and equipment in demanding industrial and commercial environments.

Key specifications

• Model: KAL361101042
• Current rating: 110 A
• Poles: 3
• Voltage rating: 600 V
• Brand: Square D

Why this configuration matters

Three poles mean balanced protection for a 3-phase distribution system, helping to interrupt fault currents across all phases simultaneously. The 600 V rating expands compatibility with typical commercial and light-industrial power supplies, while the 110 A rating matches medium-load feeders and equipment circuits. This combination provides a reliable line-side protection solution that fits standard Square D panels that require a KAL-series, 3-pole breaker.

Ideal use scenarios

• Upgrading or replacing breakers in 3-phase electrical panels where a 110 A, 3-pole, 600 V device is specified.
• Protecting feeders and motors in small-to-midsize industrial setups, warehouses, or processing equipment.
• Replacing worn or failed breakers in retrofit projects that require exact part matching by model and rating.

How to use and compatibility reminders

Confirm that the panel or distribution board accepts a Square D KAL-series, 3-pole breaker with a 600 V rating. Ensure the part number matches KAL361101042 for a precise fit and reliable operation. When installing or replacing any circuit breaker, follow your local electrical codes and, if needed, consult a qualified electrician to verify proper sizing, clearance, and torque requirements.

What sets it apart

This specific model—Square D KAL361101042—delivers a clear, exact fit for systems requiring a 110 A, 3-pole, 600 V protection device. By aligning your replacement with the exact part number and ratings, you minimize compatibility risks and downtime, ensuring your 3-phase protection remains consistent with your existing Square D infrastructure.
