Overview

The Hammond Power PFK4 (SKU: PFK4) is a primary fuse kit designed for HPS legacy control molded style transformers. This kit provides essential overcurrent protection and includes four fuse clips, four mounting screws, one jumper wire, one finger guard, and the PHAK1 instruction sheet. It is compatible with transformers up to 1500 VA and supports maximum primary fuse ratings of 30 amps, aligning with HPS transformer specifications for 125% of rated current. The PFK4 is suitable for applications requiring primary fuse protection, such as machine control panels, automation systems, and HVAC equipment. The included finger guard enhances operator safety by preventing accidental contact with live components. This kit is compatible with HPS transformer voltage groups C, G, and I, specifically for transformer part number suffixes MQMJ, PG, and MLI. The PFK4 simplifies installation with standardized components and pre-drilled mounting holes. For transformers not factory-equipped with fuse clips, the PFK4 offers a cost-effective upgrade solution. The PHAK1 instruction sheet provides clear wiring diagrams and safety guidelines to reduce installation time and minimize errors.
