Westinghouse | HKB3150 | Circuit Breaker | 150A | 3-Pole | 600V

Protect essential electrical systems with the Westinghouse HKB3150 Circuit Breaker. This 3-Pole unit is rated for 150A and 600V, built for dependable protection in commercial and light industrial panels. It’s purposefully suited for maintenance, retrofit, and replacement projects where exact specifications matter, so you can keep your electrical infrastructure running smoothly.

Key compatibility note: the part number HKB3150 is the most reliable reference for determining fit. Always confirm your panel’s ratings and the switch’s compatibility before ordering to ensure safe, code-compliant operation.

• Amperage: 150 A
• Poles: 3-Pole
• Voltage rating: 600V

Why this matters in real-world use: a true three-pole protection across all hot conductors helps maintain balance in three-phase systems and provides coordinated interruption in case of faults. By matching the exact HKB3150 specification, you reduce the guesswork during retrofits and replacements, streamlining procurement and installation.

Ideal use cases

• Replacing a worn or failed breaker in an existing Westinghouse panel that lists HKB3150
• Retrofits or upgrades in commercial or light industrial environments requiring a 150A, 3-Pole, 600V protection device
• Service disconnects in three-phase systems up to 600V that need reliable, uniform protection across all lines

Practical guidance for buyers: rely on the part number as your primary compatibility signal. Cross-check your panel documentation, labeling, or service manuals to verify that HKB3150 aligns with your bus configuration and three-phase requirements. This attention to detail helps ensure a safe, efficient, and durable protection solution for your electrical system.
