Why this Square D model stands out

Combining a robust 10kA interrupting capacity with a precise 80A rating, the Q1380 is designed to safeguard three-phase equipment from short circuits and overloads in 240V systems. The 3-pole configuration provides synchronized protection across all phases, helping prevent phase imbalances that can damage motors and drives. This makes it a dependable choice for panel upgrades, mechanical rooms, and electrical spaces where downtime is costly.

Ideal use scenarios

• Three-phase motor circuits in industrial automation, pumps, compressors, and conveyors
• Panel retrofits and replacement projects where the Q1380’s specs match the existing installation
• New or upgraded 240V commercial and light-industrial power distribution layouts

Practical tips for installation and compatibility

• Always verify that the panel and bus design accommodate a 3-pole, 240V unit with a 10kA interrupting rating before ordering.
• Use the Q1380 part number as your primary reference to ensure exact fit and ratings match your existing equipment.
• Handle with standard electrical safety protocols; ensure power is disconnected before replacement.
