The NXB-80 Miniature Circuit Breaker (MCB) provides robust overload and short-circuit protection for electrical circuits up to 80A, ensuring positive isolation and reliable operation. With a slim 18mm per pole width, it's one-third narrower than traditional 80A MCBs, significantly optimizing space within distribution boxes. Available in multiple pole configurations (1P to 4P) and with B, C, or D tripping curves, this versatile MCB is an ideal solution for efficient and safe power distribution across residential, commercial, and industrial building applications.
