Eaton Bussmann CHPV1U Fuse Holder

The Eaton Bussmann CHPV1U is a single-pole fuse holder rated for up to 30 amps at 1000 volts DC. It accepts cylindrical fuses measuring 1-1/2 inches long by 13/32 inches in diameter from compatible series such as HP10M, PV-F, SPF, SPFS and CHPV. The transparent thermoplastic body provides finger-safe protection and mounts directly on standard DIN rail for photovoltaic and DC circuit installations. Builders needing higher pole counts or AC-rated holders should look elsewhere.

Thermals noise and power draw

As a passive component the holder adds negligible resistance and generates no audible noise during normal operation. The box-lug connectors accept solid or stranded wire from 18 to 4 AWG ensuring a secure low-loss connection that runs cool within its 30-amp rating. The UL-listed and CSA-certified thermoplastic housing maintains its dielectric strength across the full 1000-volt DC range without active cooling.

Upgrade path and fit

This holder replaces open-style fuse blocks that lack finger-safe enclosures or DIN-rail mounting. The compact footprint of 2.43 inches high by 0.69 inches wide by 2.91 inches long fits tight panel layouts where older bulkier blocks cannot. The jump is worthwhile when a project requires CE-marked, UL-listed finger-safe construction and direct DIN-rail attachment for 1000-volt DC solar strings.

Questions about this item

How do I install the CHPV1U fuse holder on DIN rail and what wire range fits the box lug?

Snap the holder onto standard DIN rail; the box lug accepts solid or stranded wire from 18 to 4 AWG. Tighten the lug screws to the torque printed on the body so the connection stays secure under vibration.

What maintenance or replacement will the CHPV1U need over time?

The holder itself is non-indicating and has no moving parts, so it only needs periodic visual checks for discoloration or loose lugs. Replace the fuse — HP10M, PV-F, SPF or SPFS series, 1-1/2 in × 13/32 in — after any over-current event.

What is the first limit reached under sustained 30 A load at 1000 V DC?

The UL-listed rating caps continuous current at 30 A and voltage at 1000 V DC. Exceeding either trips the fuse; the thermoplastic body and finger-safe design remain within their thermal limits at the rated load.
