Introduction
HV HRC Fuses links are used as protection devices in the medium voltage switchgear and equipments against over current and short circuits
ESWARI (ANAND) fuses are used for protection of power distribution power equipments such as
Potential transformer.
Distribution transformer.
High voltage motors .
High voltage capacitors and.
Cables,general circuits etc.
ESWARI (ANAND) fuses are designed & manufactured to suit any type installation in indoor & outdoor.

VT Protection Fuses
transients and to ensure protection against any type of faults including inter turn shorts turn shorts arising from the potential transformer these fuse links are used as VT primary protection fuses in order to quickly limit the fault and isolate the vt from the supply source.
Ratting : 3.3 kv to 36 kv
AMPS : 0.5 to 6.3 A
Fuse links with stud / screw type connections are also available.Custom fixing arrangements can also be provided .

Motor Protection Fuses
Type NGTT,RGTT & C1 (m),NGT (m) are specially designed for motor protection application They are suitable for both direct-on-line motor starting application and in conjuction with contactors for star/delta motor starting these fuses offer protection for the motor circuit from inadmissible high over current and incase of short circuit isolation takes place at the fastest given time the fuses are designed to withstand surges due to frequent starting of the motors.
