MERSEN AND THE HV FUSE-LINKS MARKET Mersen offers a wide range of HV DIN fuse-links to be used in HV substations, HV switchgear, HV controlgear and HV systems for reliable protection of HV/LV power distribution transformers and HV distribution networks. Designed to be combined with other equipment, these current-limiting fuse-links interrupt fault currents before they reach their peak. Mersen is offering current limiting fuses with high breaking capacity, offering the best protection against short circuit current. Mersen is also a key player in innovative solutions to increase safety and efficiency:...

Fuse element in pure silver Different types of high voltage fuse-links IEC standard defines 3 types of fuse-links: Back-up, General purpose and Full range. Mersen offers Back-up and General purpose fuse-links. Back-up fuse-links range Current-limiting fuse capable of breaking...

Striker The striker is a mechanical device forming a part of a fuse-link which releases the energy required to cause operation of another switching device or signalling device. The Mersen striker is a “medium” type with an effective length of 30mm and initial force of 80N. Mersen HV fuse-links have all a striker function Mersen offers 3 different options to operate the striker in HV fuses: • First one (regular) is driven by the fuse element when it is melting • Second one (CPD) is driven by the control of the power dissipation of the fuse-link according to Ohm's law. As the back-up fuse-link...

Outdoor type Mersen offers several technologies for fuse-elements to propose a compromise between cost and performance / efficiency depending on the application. All Mersen DIN HV fuse-links are for outdoor and indoor use. The latest innovation with a new fuse-element design in cast-in-one-piece structure to reduce power dissipation. They are brown and all are tested at the end of production. PTD fuse-links were specifically developed to be installed in compact-sized enclosed substations because they have a limited thermal power acceptance. PTS fuse-links were specifically designed with low power...

LIMITOR®-B BACK-UP FUSE LINKS ACCORDING TO IEC 60282-1 HV fuse-links standard: DIN 43625 DIN 43625 defines the dimensions of HV DIN fuse-links. All Mersen HV DIN fuse-links are in compliance with this standard. The diameter "d” is mainly related to the current rating (50 to 88mm) and the length "e” is mainly related to the voltage rating (192 to 537mm). DIN 43625 defines lengths in accordance with voltage rated like shown in the table below:

Bases with optional indicator

INDICATING DEVICES The indicating device enables electrical actuating of the opening mechanism for a circuit or triggering of an indicator during the melting of a fuse equipped with a trip-indicator. This very robust and original device means freedom for any mechanical system and offers the advantage of being able to incorporate a microswitch unit or units according to the equipment configuration.

HV fuses standard: IEC 60282-1 High-voltage fuses - Part 1: current-limiting fuses This part of IEC 60282 applies to all types of high-voltage current-limiting fuses designed for use outdoors or indoors on alternating current systems of 50 Hz and 60 Hz and of rated voltages exceeding 1000V. This standard defines test set-up, fuse characteristics and normal service conditions (without derating) like: • Operating temperature: -25°C to 40°C • Altitude: 1000m maximum It is advisable to replace all three fuse-links when the fuse-link on one or two phases of a three-phase circuit has operated, unless...

Rated voltage range It is important for HV fuse-links that they must be operated at the voltage for which they have been rated. Accordingly, the operating voltage corresponds to the maximum rated voltage of the fuse-link. Owing to the switching voltage occurring during arcing, the fuse-link cannot be used at lower voltages without limitation. A lower operating voltage at which the fuse-link can still be used without exceeding the system insulation level during extinction must therefore be taken into account. From these two values results the permissible voltage range of the fuse-link, which is...
