Fuses

The most current-limiting UL-Class fuse, Mersen’s Class J fuses provide optimal performance, prevent interchangeability with older code fuses, and save valuable panel space.

Broad range for high voltage fuses for transformer protection.

Mersen R-Rated fuses are current-limiting, high interrupting rating fuses intended for the short circuit protection of medium voltage motors and motor controllers.

Mersen fuses for the protection of transformers and distribution lines deliver overload and short circuit protection, and are designed to withstand the transformer magnetizing inrush current.

With the evolution of DC distribution and new technologies on the horizon, Mersen’s MDC DC Distribution Series is the product line to help customers achieve ultimate protection for today and tomorrow. The product portfolio allows system integrators and OEM manufacturers to select fuses easily for the protection of DC distribution in a variety of applications.

The MDC Series incorporates proven fuse technologies which provide optimal current limitation while achieving maximum performance. The MDC portfolio is designed to easily allow customers to choose fuses where coordination with other DC components is critical, eliminating unnecessary downtime.

DQS series fuses are specifically designed to reduce the I2t, peak let-through current, and arc voltages during fault conditions to protect applications such as battery charging systems and other DC components like relays and contactors.

Mersen R-Rated fuses are current-limiting, high interrupting rating fuses intended for the short circuit protection of medium voltage motors and motor controllers. R-Rated fuses are back-up fuses that have a minimum interrupting rating, and must be coordinated with overload relays in combination motor starters. The motor starter manufacturer generally specifies the R-Rated fuse size. These fuses come with a 3 (size D) or 4 (size E) inch diameter barrels with ferrules and are mounted in spring reinforced clips
