ABB Spec-Setter Class R Fuse Conversion Kit for Safety Switches

The ABB Spec-Setter Class R Fuse Conversion Kit upgrades compatible ABB safety switches for use with current-limiting Class R fuses, with kits available at 30A, 240V for ABB's rugged, reliable Spec-Setter safety switch line. The Spec-Setter platform spans general duty switches for residential and light commercial use as well as heavy-duty switches for demanding commercial and industrial applications, and this conversion kit helps keep the enclosure code-compliant and ready for Class R fuse protection whether the installation calls for a general duty switch, a heavy-duty switch, or a double throw switch for emergency generator backup.

ABB TRK12B – Frequently Asked Questions

1) What does the ABB Spec-Setter Class R fuse conversion kit actually do to a safety switch?
It converts the fuse clips in a compatible ABB Spec-Setter safety switch so the enclosure accepts Class R fuses instead of standard Class H/K style fuses. Class R fuses are current-limiting, so the conversion is what lets the switch provide current-limiting overcurrent protection and stay code-compliant where Class R is specified. It ships one kit per unit, so you order one kit per switch you are converting.
2) Which ABB fuse rejection kit do I order for a 30 amp safety switch?
For 30 amp switches the kit is TRK12B at 240 volts, or TRK16B for the 600 volt version. The amp rating of the kit has to match the amp rating of the switch you are converting, since the rejection clips are sized to the fuse body they accept.
3) Is there an ABB Class R conversion kit for 60 amp and larger switches?
Yes. Beyond the 30 amp kits, the range covers 60 amperes (TRK22A and TRK26A), 200 amperes (TRK46A), and 400 amperes (TRK56A). Pick the kit that matches the ampere rating of the switch, not the size of the load.
4) Do I need the 240V or the 600V version of the ABB TRK fuse kit?
Match the kit to the switch voltage class. TRK12B is the 240 volt 30 amp kit; TRK16B is the 600 volt 30 amp kit. A 240 volt kit is sized for 250 volt class fuse bodies and will not accept the longer 600 volt class fuse, so a 480V or 600V three-phase disconnect needs the 600 volt kit.
5) Will this ABB kit work on a general duty switch, or only heavy duty?
Both. The Spec-Setter line spans general duty switches for residential and light commercial work and heavy-duty switches for commercial and industrial installations, and the conversion kits are intended for that line across both duty ratings. They also apply to double throw switches used for emergency generator backup.
6) Can I use a Class R fuse in my disconnect without installing a rejection kit?
Physically, yes, a Class R fuse drops into standard Class H/K clips. But without the rejection kit the switch is not a Class R rated device, and nothing stops the next person from putting a non current-limiting fuse back in. If the drawing or the equipment short circuit current rating calls for Class R protection, the rejection clips are what makes the installation hold. That is the whole point of the TRK kit.
7) Is the ABB TRK conversion kit a field retrofit or does it have to be factory installed?
It is a field conversion. The kits are meant for upgrading existing ABB safety switches already in service as well as for new installs, and panel or enclosure retrofits that now need current-limiting fuse protection are a listed application. One kit handles one switch.
8) Does the ABB Class R kit come with fuses?
No. The TRK kit is the rejection hardware that adapts the switch fuse clips; the Class R fuses themselves are ordered separately and sized to the circuit. Supplied one kit per unit.
