Square D FA3610018M 100A 3-Pole 600 V Circuit Breaker

Square D FA3610018M 100A 3-Pole 600 V Circuit Breaker is a robust three‑pole protective device designed to guard three‑phase electrical systems. With a 100‑amp rating and a maximum voltage of 600 V, this breaker delivers reliable overcurrent protection for demanding industrial and commercial applications.

Key specifications

• Part number: FA3610018M
• Current rating: 100 A
• Poles: 3
• Voltage rating: 600 V

Why this matters for your system

Three‑pole protection ensures all three phases are interrupted simultaneously, reducing the risk of partial energization that can damage motors, transformers, and other equipment. The FA3610018M is purpose‑built for three‑phase circuits, delivering coordinated trip performance that helps minimize downtime and protect both people and gear in electrical rooms and equipment enclosures.

Ideal use cases

• Protection for three‑phase motors and equipment in manufacturing lines, pumps, conveyors, and compressors
• Power distribution protection in electrical rooms and industrial panels handling up to 600 V
• Upgrading legacy or single‑phase installations that require true three‑phase overcurrent protection

How it integrates and operates

Designed to be installed in compatible panels and enclosures that support 3‑pole configurations, this breaker provides a straightforward path to reliable circuit protection. When abnormal current is detected, the internal mechanism trips, cutting power to all phases and helping prevent equipment damage and electrical hazards.

Practical tips for use

• Verify panel compatibility and torque specifications for secure connection and reliable operation
• Ensure the load centers and distribution panels you use are rated for up to 600 V and three‑phase configurations
• Regularly inspect panel enclosures and wiring for signs of wear or overheating during routine maintenance checks

Choose the Square D FA3610018M when you need dependable three‑phase overcurrent protection that aligns with industrial power standards. Add it to your order to safeguard three‑phase circuits up to 600 V and keep your equipment running smoothly.
