690 V aR Circuit Protector

This 690 V aR circuit protector is built for industrial electrical systems that require fast-acting semiconductor protection. The spiral-style ceramic square tube houses a 50 A rated element designed to interrupt fault currents quickly. It suits panel builders and maintenance engineers specifying line protection for power conversion equipment.

Suits 50 A semiconductor circuits.

The device suits installations where aR-class performance is specified for 50 A loads at 690 V. It does not suit general-purpose wiring protection that calls for gG or gL characteristics. Buyers needing a different current rating or voltage class should look at other models in the range.

50 A rating at 690 V

The single specification that decides fit is the 50 A rating at 690 V with aR time-current behaviour. Verify that the system design calls for exactly this rating and characteristic before ordering.

Questions about this item

When does the 50 A aR fuse-link need replacement?

Replace it after any over-current event that causes the element to melt; the device is single-use and cannot be reset.

What sustained load will reach the 50 A rating first?

Continuous current at or above 50 A will open the fuse; the 50 A rating is the limiting threshold.

How much heat does the ceramic square tube generate at 690 V continuous operation?

Power loss appears as heat across the element; ensure the holder and wiring are rated for the resulting temperature rise.
