  • ‘T’ Range is suitable for outdoor use.
Cooper Bussmann ‘T’ Range

The Cooper Bussmann ‘T’ range medium voltage current-limiting fuse links to dimensional standard DIN 43625, are one of the most advanced design of medium voltage fuse links available anywhere in the world today. Developed by Cooper Bussmann, they comply with the very latest requirements of IEC 60282-1, are lead and cadmium free (meeting the RoHS and WEE directives) and have been designed to meet current and future global electrical utility specifications.

Cooper Bussmann ‘F’ Range

The ‘F’ range fuse links have ‘full range’ clearing capability. Cooper Bussmann ‘F’ fuse links types are designed to clear low overloads right down to the fuse links’ rated current in accordance with latest IEC 60282-1 requirements. They are thus suitable for use as a sole form of protection. ‘F’ range time-current characteristics are especially advantageous for transformer protection applications.

Cooper Bussmann ‘A’ Range

This earlier, well proven, design has values of minimum breaking current between the ‘T’ and ‘F’ range including higher current ratings.

Application

MV DIN fuse links are suitable for primary side transformer protection, fuse switch combination unit, fuse bases and fuse switches.

Medium Voltage Motor Fuse Links

  • Motor Fuse Links comply with IEC 60282-1, IEC 644 and BS 5907.
  • Available in DIN 43625 and BS 2692 dimensions.
  • Sold in a wide range of ratings from :
    3.6kV - 5 to 450A,
    7.2kV - 5 to 355A.
  • North American dimensioned products also available, 2R to 24R ratings.
Cooper Bussmann Motor Fuse Links

Cooper Bussmann range of motor fuse links are designed to meet the specific requirements necessary for motor protection. During the starting cycle of direct on-line motors, the fuse elements will reach a considerably higher temperature than during normal operation; this is due to the high amount of current the motor will draw as it starts, typically, 6 times its normal load current value. This results in expansion and contraction of the fuse elements and could cause premature operation of the fuse link. Cooper Bussmann motor fuse links encompass an advanced design to minimise this effect. This therefore, negates the need to over specify the fuse rating due to high values of motor starting current.

Cooper Bussmann fuse links operate extremely quickly under heavy fault currents, resulting from the time-current characteristic. Low power dissipation ensures low temperature rise, important in multi-tier starters for example. Switching (Arc) voltages are lower than permitted values, therefore, 5.5kV fuse links are also suitable for 4.8kV and 2.4kV circuits.

Application

Fuse links provide short-circuit protection in motor circuits to both the motor starter and cables from the starter to the motor. Overload protection is provided by the motor starter, generally by an overload relay and contactor. Combination striker tripping may also form part of the associated equipment which houses the fuse links and motor starters.

Auxiliary Transformer Fuse Links

  • British Standard Voltage and Auxiliary Transformer (VT) fuse links.
  • A range of voltage transformer primary fuse links to BS 2692-1 and IEC 60282-1.
  • Wide range of ratings from 1kV to 36kV.
  • 3.15 Amp industry standard current ratings.
  • CAV range with ratings from 3.6kV to 38kV.
Cooper Bussmann Auxiliary Transformer Fuse Links

Cooper Bussmann manufactures a wide range of voltage transformer (VT) fuse links. In North America they are referred to as Potential Transformer fuse links. These fuse links are designed for use in the primary side of voltage transformers to provide system isolation in the event of faults occuring in the transformer circuit.

Voltage transformer fuse links have a preferred current rating of 3.15A. Experience has shown that there is a risk of spurious operation by transient overcurrents where lower current ratings are used. In addition, in order to minimise the risk of deterioration of the fine fuse elements caused by corona, it is desirable to mount the fuse links so that the earthed metal is not in the immediate vicinity of the part of the barrel between the ferrules.

Higher current and ‘E’ ratings are available for special applications, including auxiliary transformers.

Application

Small rated fuse links for protection of voltage and auxiliary transformers. Back-up protection up to 3.15A and voltages from 1.1kV to 36kV.
