560 A Ceramic Square Tube Fuse

The MIRO NT3 RT16-3 NH3 RT20-3 RO34 is a 560 A ceramic square tube fuse rated for 500/690 V line protection. It belongs to the circuit protectors category and is supplied new for industrial electrical installations. The gG characteristic provides general-purpose overcurrent protection for cables and equipment.

Replaces Lower-Rated or Blown Fuses

This fuse replaces a unit of the same NT3 RT16-3 NH3 RT20-3 RO34 series when the original has operated or when a circuit is upgraded to a 560 A rating. The jump is worth it when the protected circuit demands the full 560 A capacity at 500/690 V and the existing holder accepts the ceramic square tube form factor.

Suits Industrial Panel Builders

It suits engineers specifying gG protection for 560 A circuits at 500/690 V. Buyers who need a different current rating, a different voltage rating, a different body style or a different tripping characteristic should look at other products.

Questions about this item

What fuse holder size does the NH3 RT20-3 RO34 ceramic square tube fuse require?

The fuse follows the NH3 RT20-3 RO34 series dimensions, so it fits standard NH3 fuse bases rated for 500/690V.

How do you install the NT3 RT16-3 ceramic square tube fuse without damaging the contacts?

Align the square tube ends with the NH3 fuse base clips, press straight in until fully seated, and avoid twisting the ceramic body during insertion.

When should the 560A gG 500/690V ceramic square tube fuse be replaced after a fault?

Replace the fuse after any over-current event that causes it to operate, as the gG element is single-use and cannot be reset.
