Overview

The ABB Spec-Setter TRK66A Class R Fuse Field Conversion Kit (SKU: TRK66A) is a field-installable solution designed to convert ABB Spec-Setter safety switches to accept only Class R fuses, ensuring NEC compliance and preventing unauthorized fuse substitutions. Manufactured by ABB Electrification, a global leader in electrical solutions, this kit is compatible with multiple Spec-Setter switch models, including THN3321, THN3361, TH3365MSS, THF4366A1CN4, THF3366AS1, TH3366MSS, and THF3366A12. The TRK66A is rated for 3-pole, 3-wire configurations with a 240Vac rating and is suitable for NEMA Type 1 and 3R enclosures, providing versatile indoor/outdoor protection. Key features include a field-reversible load-block for easy integration into existing systems, eliminating the need for complex modifications. This kit is particularly valuable in applications where NEC compliance is critical, such as manufacturing plants, commercial buildings, and utility installations. By integrating the TRK66A, you reduce the risk of misapplied fuses, minimize downtime, and ensure long-term operational integrity. The TRK66A is non-fusible and designed for retrofitting legacy equipment or specifying new installations. It is distributed by Gross Automation and is engineered to work with Spec-Setter safety switches, including models with amperage ratings of 200, 400, and 600. The kit ensures durability and compliance, providing peace of mind with ABB’s trusted performance. For switches requiring Class J fuse compatibility, some models allow adaptation by moving the load-block toward the switch base, as noted in ABB’s specifications.
