Fuse Replacement - Heater Protection

aR and gR indicate Ultra-Rapid response for protecting sensitive semi-conductors.

aR provides short circuit protection while gR provides overload and short circuit protection (effectively a faster response).

Either should be suitable for protecting an industrial resistive heater which generally needs only a slower-responding fuse such as a gL or gG.

Maybe you would like to find out why it blew in the first place??

aR rating is for semiconductor protection while Very very Fast

Fusing elements are so designed to have 3-4 fusing points in series and 2-3 such elements in parallel to ensure max number of fusing points having the highest burn-out probabillity. Pure Silver is used

These are only Short circuit protection. Have very low I² t to cutoff in µS

gR is for Cables and general protection Slugish. I² in mS/S

These are overload protection fusing elements are normally pure copper; but its design is same as aR fuses.

• gR-type: full range protection. Overload and short circuit protection.
• aR-Type: partial range protection. Short circuit protection only. Faster acting than full range fuses
