Description
Engineered to disconnect ungrounded and grounded conductors simultaneously, this 30-amp switch neutral component is essential for specialized applications like fuel dispensers. It operates on 120VAC systems while utilizing a two-pole footprint. The unit fastens securely into Square D NQ and legacy NQOD panelboards using a standard bolt-on configuration. Safety is enhanced by the inclusion of Visi-Trip technology, which displays a highly visible red indicator when a fault occurs.

Reviews Summary
Customers say these electrical breakers arrive exactly as ordered and work perfectly for their intended applications. They consistently praise the competitive pricing, which many report is significantly lower than local suppliers. Fast shipping and prompt delivery are frequently highlighted, with many receiving orders within days or even next-day delivery for urgent needs. The breakers arrive well-packaged and in excellent condition. Many reviews emphasize the company's extensive inventory availability, particularly for hard-to-find breakers.
