FAQs

 

What is the RT28 Cylindrical Contact Caps Fuse Protector used for?

It’s designed for AC circuits up to 500V to protect against overload and short-circuit faults in lighting systems, industrial control panels, and low-voltage distribution boards.

 

What is the function of the neon indicator (“X” type)?

The “X” version includes a built-in neon light that provides a visual signal when the fuse link has blown, enabling quick maintenance without removing the protector.

 

Can the RT28 be installed in high-altitude areas?

Yes, but current ratings should be derated: 0.9×In at 2500m and 0.8×In at 3000m, ensuring reliable operation under reduced air pressure.

 

What’s the difference between RT28-32 and RT28-63 models?

RT28-32 supports fuse links up to 32A (10×38mm), while RT28-63 supports up to 63A (14×51mm). Both share the same modular structure but differ in size and rated current range.

 

Is the RT28 suitable for use in capacitor banks?

It’s not recommended for capacitor circuits; RT36-00 Fuse Protector is advised instead.
