Mersen L232517

The NH fuse-link aM, rated at 500VAC and 315A, is designed for use in plug-in fuse systems. This system includes a fuse base, which may contain terminal covers and phase barriers, along with a fuse-link featuring blade contacts. Due to its design, the non-interchangeability of rated current is not guaranteed, necessitating handling by qualified professionals.

These type aM fuse-links are characterized by their partial-range breaking capacity, making them suitable for protecting motor circuits. They provide strong current limiting and exhibit low power losses, interrupting currents up to 6.3 times the nominal current (In) and reaching their maximum breaking capacity. Consequently, they are effective for short-circuit protection but should be paired with additional switchgear for overload protection. The rated current of these fuse-links can match the motor's nominal current, ensuring compatibility in various applications.

This model features a body width of 52 mm and utilizes ceramic as the insulating material. The connection terminal is made of silver-plated copper, contributing to the reliability of the electrical connection.
