What makes this breaker stand out
- Exact-match compatibility: The HQNB3030 is purpose-built for panels and installations that require a three-pole, 240V bolt-on protection device, helping reduce guesswork during replacements.
- Efficient, secure installation: Bolt-on mounting provides a robust mechanical connection, contributing to stable performance and cleaner wiring layouts during retrofit or service work.
- Plug-and-play replacement mindset: When you have a Westinghouse system that specifies HQNB3030, you’re aligning with the intended design for streamlined swaps and consistent protection characteristics.
