Diversitech 626-hasr15 Time Delay Fuse 600V 15A RK5

Product Description

The DIVERSITECH 626-hasr15 is a time-delay fuse rated for 600 volts and 15 amps in an RK5 form factor. Time-delay fuses are designed to tolerate brief inrush currents common in motor-start applications while still providing reliable overcurrent protection under sustained fault conditions. This fuse is a standard component in HVAC, refrigeration, and light commercial electrical systems where motors, compressors, and similar inductive loads require protection. Licensed electricians and HVAC technicians are the primary installers.

This fuse is suited for residential and light commercial applications where RK5-class overcurrent protection is required. Typical installation locations include disconnect boxes, load centers, and fused switches serving HVAC condensing units, air handlers, and refrigeration equipment. The RK5 classification ensures it fits in rejection-style fuse blocks that prevent installation of lower-rated fuse classes, adding a layer of system protection.

Key Features

• 600-volt rating supports a wide range of single-phase and three-phase circuits
• 15-amp rating suitable for compressor and motor branch circuit protection
• RK5 class time-delay design accommodates motor inrush without nuisance blowing
• 5-inch length fits standard RK5-rated fuse holders and disconnect blocks

Compatibility

Designed as an OEM-style replacement for RK5 time-delay fuses used in residential and light commercial HVAC disconnect and overcurrent protection applications.

Installation Notes

Installation must be performed by a licensed electrician or qualified HVAC technician in accordance with applicable NEC requirements. Always disconnect and lock out power at the main panel before servicing fuse holders or disconnects. Verify the replacement fuse class, voltage rating, and amperage match the original equipment manufacturer specifications before installation. Do not substitute a standard fast-acting fuse where a time-delay fuse is specified.
