Meet the Westinghouse HKA3150 – a rugged, three-pole circuit breaker crafted for dependable overcurrent protection in 3‑phase power systems. With a 150A rating and a 600V maximum operating voltage, this unit is designed to safeguard commercial and industrial electrical distributions while delivering reliable performance when it matters most. Its 35kA interrupting capacity ensures swift fault interruption to help minimize damage and downtime in the event of a short circuit.
Key specifications
- Amperage: 150 A
- Poles: 3-Pole
- Voltage: 600 V
- Interrupting capacity: 35 kA
- Part number: HKA3150
- Applications: maintenance, retrofit, and replacement projects requiring exact spec matching
Designed for retrofit, maintenance, and replacement
The HKA3150 is purpose-built for projects where matching exact specs matters. Whether you’re upgrading an aging system, replacing a failed breaker, or retrofitting to accommodate new loads, this unit provides the critical protection you need while staying aligned with your existing 3‑phase infrastructure.
Compatibility and installation tips
Important: Always confirm fit and ratings before ordering. The part number is the most reliable reference for compatibility with your panel, switchgear, or feeder arrangement. When in doubt, verify that your system calls for a 150A, 3‑pole, 600V device with a 35kA interrupting capacity to ensure proper operation and safe, code-compliant performance.
Who benefits from the Westinghouse HKA3150
This breaker is ideal for facilities with 3‑phase distribution needs in commercial and industrial environments.
