Product details

The DF2KA1631 is a set of three DIN NH3 blade fuses from the TeSys GS range, rated 630 A at 500 V AC with an aM (motor-protection) time-current curve. The aM curve means it handles motor inrush without nuisance blowing but clears a fault fast enough to protect downstream contactors and cables — standard for motor branch circuits. NH3 blade size tells you the physical footprint: these slot into NH3-style fuse holders or switch-disconnectors common in 630 A distribution panels.

Obsolete. No factory order stream remains. The set of three fuses ships as a matched batch. Submit an RFQ with your quantity and delivery window.

Frequently asked questions

What is the closest alternative to DF2KA1631?

No official successor order code is listed. For a functional equivalent, look for another DIN NH3 aM 630 A 500 V AC fuse set from the same TeSys GS family — confirm blade dimensions and striker presence match your holder.

What is the fuse size and curve?

NH3 blade size, aM motor-protection curve. The aM curve is designed for motor branch circuits — withstands starting inrush but clears quickly on sustained overloads or short circuits.
