Description
The Littelfuse NLS-400 is a 400-amp, 600-volt Class K5 fuse designed for general-purpose feeder and branch circuit protection. It is a fast-acting fuse, meaning it responds quickly to overcurrent conditions to prevent damage to electrical systems. The NLS series is an economical choice for applications where lowest initial cost is a priority. It has a 50,000-amp interrupting rating, making it suitable for residential, commercial, and smaller industrial applications where short-circuit currents are relatively low.
