Allen-Bradley 1489-M3D040 is a rugged 4-amp, 3-pole circuit breaker designed for demanding industrial electrical service, maintenance, and replacement projects. This unit protects 277V three-phase circuits, delivering reliable protection for critical loads in commercial and industrial environments.

  • Part number: 1489-M3D040
  • Amperage: 4 A
  • Poles: 3
  • Voltage rating: 277V

Designed for installations that require a three-pole breaker to safely interrupt all three phases, the 1489-M3D040 is well-suited for panel replacements, system upgrades, and spare stock for manufacturing lines that rely on steady 277V distribution.

Why this model stands out: it’s a genuine Allen-Bradley circuit breaker, built for rugged reliability in industrial panels and field-service environments. To ensure a perfect fit, verify compatibility by the part number and review your application requirements—voltage, current, and pole configuration—before ordering.
