Product description
Shipping

Powerful, reliable protection for demanding 600V three-phase systems, the Westinghouse MA3350S Circuit Breaker delivers 350A of resilient overcurrent protection in a 3-pole package. Built for maintenance, retrofit, and replacement projects, this unit ensures you can upgrade or service your electrical distribution with confidence when your spec requires exact part-level compatibility.

Key specifications and what they mean for you

  • Amperage: 350A continuous current rating handles heavy loads in commercial and light-industrial distributions.
  • Poles: 3-Pole configuration guards all three hot legs in a 3-phase system.
  • Voltage: 600V maximum system voltage supports typical industrial power networks.

Why choose the MA3350S for retrofit, maintenance, or replacement

The MA3350S is specifically selected when the goal is precise spec matching. Using the exact part number as your compatibility reference minimizes the risk of misfits in panels and enclosures, reducing installation delays and downtime.

Practical use scenarios

  • Retrofit an aging panel that previously used a 350A, 3-pole, 600V breaker to restore protection without altering the system design.
  • Replace a failed breaker in industrial equipment racks or service panels where 600V, 350A, 3-pole protection is required.
  • Maintenance upgrades in facilities that segment heavy loads across multiple circuits, ensuring reliable fault interruption on each leg.

Installation and compatibility notes

Always confirm fit and ratings before ordering. The MA3350S part number is your best reference to ensure compatibility with your existing breaker profile and panel catalog. If you have a mixed-technology panel, verify that the replacement matches the exact trip characteristics and mounting style used in your current setup.

What you get

One Westinghouse MA3350S Circuit Breaker designed for robust protection in 600V systems, ready for installation by qualified electrical professionals who follow local codes and safety standards.
