Abb TRK46A Fuse Rejection Kit 100A to 600A

Product Description

The ABB TRK46A is a Type R fuse rejection kit designed for use with ABB safety switches rated from 100 amps to 600 amps. This kit modifies the fuse block within a compatible safety switch to accept only Type R rejection-style fuses, preventing the inadvertent installation of non-current-limiting fuses in circuits where rejection protection is required. Installation is performed by licensed electricians during switch service or new installation. The TRK46A is a direct ABB accessory, ensuring a proper fit within the switch enclosure without field fabrication or modification.

This rejection kit is applicable to residential, commercial, and industrial electrical installations where NEC compliance requires the use of rejection-style fuses. It is commonly installed in safety switches serving HVAC equipment, motor loads, and general-purpose feeder circuits. The kit is especially relevant in retrofit scenarios where an existing switch must be upgraded to enforce fuse rejection without replacing the entire switch assembly.

Key Features

• Enforces Type R fuse rejection to prevent incorrect fuse installation
• Compatible with safety switches rated from 100 amps to 600 amps
• Direct ABB accessory for accurate fitment within ABB switch enclosures
• Supports NEC compliance in circuits requiring current-limiting fuse protection
• Allows existing switch upgrades without full assembly replacement

Compatibility

Designed for use with ABB safety switches in the 100A to 600A range that accept Type R fuse rejection kit accessories. Consult the switch documentation to confirm kit compatibility before installation.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out the circuit at the upstream overcurrent device before opening the switch enclosure or handling fuse block components. Follow ABB installation instructions for proper seating and retention of the rejection clips within the fuse block. Do not install this kit while the switch is energized.
