Cylindrical fiberglass solar fuse, 5-1/2 inches long, 1-1/16 inch diameter, rejection style

Bussmann

Bussmann PVS-R-50 Solar Fuse 50A 600V AC/DC Class RK5 line protection

SKU CH-A23Z-K24V2

A 50 A, 600 V AC/DC Class RK5 solar fuse with 200 kA AC and 20 kA DC interrupt ratings, UL 2579 listed for photovoltaic line protection

  • Fast-acting protection clears faults quickly
  • 50 A rating matches typical solar string currents
  • 600 V AC/DC rating suits photovoltaic systems
  • 200 kA interrupt rating at 600 V AC handles high fault energy
  • UL 2579 and CSA C22.2 certified for code compliance

Solar fuse for photovoltaic systems

This fast-acting fuse protects PV strings at 50 A and 600 V AC or DC. It is built to Class RK5 requirements for rejection-style holders in solar combiner boxes and disconnects.

Fits RK5 rejection holders in combiner boxes

The cylindrical fiberglass body slides into standard RK5 clips, freeing panel space because no separate indicator window is needed. CSA certification and UL 2579 listing cover the photovoltaic application.

Sustained fault interruption at rated voltage

Interrupt rating reaches 200 kA at 600 V AC and 20 kA at 600 V DC, so the element clears heavy faults without prolonged arcing. Single-element construction maintains consistent let-through energy during extended overloads.

Questions about this item

What continuous current does the 50 A PVS-R-50 fuse allow before it opens?

The fuse is rated for 50 A continuous current and will open when that limit is exceeded under sustained load.

How much heat does the cylindrical fiberglass body dissipate during all-day operation?

The fuse body is 5-1/2 in long by 1-1/16 in diameter and is made of fiberglass; heat dissipation depends on the surrounding enclosure and airflow.

What fuse holder or block is required to install this Class RK5 rejection fuse?

A Class RK5 rejection-style fuse block that accepts a 5-1/2 in by 1-1/16 in cylindrical fuse is required for proper installation.
