Why Choose the Mersen NH00UD69V20PV High-Speed Fuse?

The Mersen NH00UD69V20PV is a compact NH00 high-speed fuse link designed to protect sensitive power semiconductor equipment against damaging overcurrents and short circuits. Manufactured by Mersen, a specialist in electrical protection technology, this fuse is suitable for demanding industrial power-conversion and electronic equipment.

High-speed fuses operate more rapidly than conventional industrial fuse links, helping to limit the peak current and energy transmitted during an electrical fault. This fast response is particularly important when protecting semiconductor devices whose internal components can be damaged before a standard fuse has time to disconnect the circuit.

With a rated current of 20 A and a voltage designation of 690 V, the NH00UD69V20PV provides dependable protection within compatible installations. Its standard NH00 blade-contact format supports secure installation in an appropriate NH fuse base, switch disconnector or fuse holder.

Key Advantages

  • Fast-acting semiconductor fuse protection.
  • 20 A rated current for compatible power circuits.
  • 690 V voltage designation for industrial electrical applications.
  • Low let-through energy helps protect sensitive electronic components.
  • Standard NH00 blade-contact construction.
  • Suitable for industrial power conversion and semiconductor equipment.

Key Features

  • Mersen high-speed fuse link.
  • NH00 fuse size.
  • 20 A rated current.
  • 690 V voltage designation.
  • Rapid fault-current interruption.
  • Low energy let-through characteristics.
  • Blade contacts for compatible NH fuse equipment.
  • Designed for professional industrial installation.

Rapid Protection for Sensitive Power Electronics

Power semiconductors used in drives, rectifiers, inverters and industrial power supplies can be highly sensitive to excessive current. A high-speed fuse limits both the magnitude and duration of fault current, reducing the thermal and mechanical stress placed on protected components.

The Mersen NH00UD69V20PV is designed for use where rapid circuit interruption is required. Correct fuse selection should consider the circuit voltage, continuous operating current, prospective fault current, time-current characteristics and the energy withstand capability of the protected semiconductor device.

Typical Applications

  • Variable-speed drives and motor-control equipment.
  • Industrial rectifiers and converters.
  • Uninterruptible power supplies.
  • Power semiconductor protection.
  • Industrial inverters and power supplies.
  • Automation and electrical control panels.

Frequently Asked Questions

What is the Mersen NH00UD69V20PV used for?

The fuse is used to provide fast overcurrent and short-circuit protection for compatible power semiconductor equipment, converters, drives and industrial electronic systems.

What is the rated current of this fuse?

The Mersen NH00UD69V20PV has a rated current of 20 A.

What does the NH00 designation mean?

NH00 identifies the physical fuse size and blade-contact format. The fuse must be installed in a compatible NH00 fuse base, holder or switch disconnector.

Can this high-speed fuse be replaced with a standard NH fuse?

A standard general-purpose fuse should not be used as a direct replacement unless the equipment manufacturer confirms compatibility. High-speed fuses have specialised operating characteristics for protecting sensitive semiconductor devices.

What should be checked before installing this fuse?

Confirm the complete part number, rated current, circuit voltage, fuse class, breaking capacity and compatibility with the installed NH00 fuse holder and protected equipment.
