Westinghouse FB3190SMRL - 25A, 3-Pole, Circuit Breaker

The Westinghouse FB3190SMRL 25A, 3-Pole Circuit Breaker is built for reliable protection where three-phase power meets demanding commercial, industrial, and OEM environments. With a 25-amp rating and a 3-pole configuration, this breaker delivers synchronized trip across all three phases, helping keep motors, feeders, and control circuits safe from overcurrent events.

Why this 25A, 3-Pole breaker stands out

• Three-phase protection you can trust. The 3-Pole design ensures simultaneous disconnection of all live conductors in a 3-phase system, reducing the risk of unbalanced loads and equipment damage.
• Optimized for practical panel layouts. Ideal for panelboards, switchboards, and control panels where compact, straightforward protection is essential for reliable operation.
• Solid, ready-to-integrate performance. Designed for industrial, commercial, and OEM applications, delivering dependable overcurrent protection and safe operation in distribution panels and motor control centers.
• Exactly the right protection level. The 25A rating provides targeted protection for feeders and equipment where higher ampacity would risk nuisance trips, while still enabling smooth startup of connected loads.

Applications and practical use cases

• Protect three-phase motors and feeders in motor control centers and distribution panels.
• Enforce reliable overcurrent protection in commercial switchboards serving heavy machinery and equipment loads.
• Serve as a retrofit or replacement component in compatible Westinghouse installations, maintaining consistency across protection devices.
• Support OEM equipment where a standard, dependable 3-pole breaker is required to meet electrical safety and performance standards.

What makes it the right choice for your project

• Clear compatibility. Aligns with Westinghouse protection schemes and fits into panels designed for 3-pole breakers, helping you maintain a coherent protection strategy across your electrical infrastructure.
• Focused protection for performance-critical systems. By safeguarding three phases together, it helps minimize anticondition risks in power-hungry applications like motors and drives.
• Durable, job-ready design. Built for steady operation in demanding environments, reducing the chance of unexpected trips that can halt production or service uptime.

Tips for installation and best practices

• Verify panel compatibility and confirm the FB3190SMRL’s fit within the designated bus or mounting framework before installation.
• Ensure wiring aligns with three-phase layouts and that all conductors are securely terminated to maintain consistent protection across all phases.
• Document the protection level (25A, 3-Pole) in your electrical drawings and maintenance logs to support future service and replacements.
