RS32 125A aR ceramic square tube fuse

This fuse is a fast-blow line protection device rated at 125 amps for 690V and 660V systems. It uses a ceramic square tube body to interrupt fault currents quickly. The component suits industrial power circuits requiring reliable overcurrent protection. It is supplied new for maintenance and installation work.

Suited for 125 amp fast-blow requirements

This part fits applications needing a 125A aR characteristic fuse in a ceramic square tube format. It is not for circuits operating above 690V or below the rated voltage where coordination differs. Buyers who need a different ampere rating or a slower time-current curve should look at something else. The specific RS32 series form factor must match the holder exactly.

125 amp rated current defines the protection limit

The 125A rating is the single value that decides if this fuse matches the circuit design. It sets the maximum continuous current the device will carry without opening. The 690V and 660V voltage ratings must also agree with the system potential. Confirm both numbers against the equipment specification before fitting.

Questions about this item

How much heat does the RS32 125A aR fuse generate when running continuously at 125 A?

The ceramic square tube body dissipates heat efficiently during continuous operation at the rated 125 A, keeping temperature rise within the limits defined for aR-class fast-blow line protection.

What holder or mounting hardware is required to install the RS32 125A aR fuse in a 690 V circuit?

The fuse fits standard RS32-series ceramic square tube holders rated for 690 V/660 V; verify the holder’s ampere rating matches 125 A before installation.

Will the RS32 125A aR fuse coordinate with older 660 V-rated breakers already in the panel?

Yes, the dual 690 V/660 V rating allows the fast-blown fuse to operate selectively alongside existing 660 V circuit breakers without nuisance tripping.
