NewTrend · photovoltaic DC fuse holder
Product overview
The TOPV-32X is a DIN-rail fuse holder for 10 × 38 mm photovoltaic fuse links. Single- and multi-pole assemblies are shown with and without an indicator window. This listing is for the holder; fuse links are separate.
Technical selection summary
| Model | TOPV-32X |
|---|---|
| Fuse size | 10 × 38 mm |
| Voltage reference | 1100 V DC |
| Poles | 1P, 2P, 3P and 4P |
| Indicator | With or without indicator, illustrated versions |
| Holder marking | Ie 1–30 A on the illustrated housing |
| Source fuse compatibility list | 3, 10, 15, 20, 25, 30 and 32 A. The 32 A family entry exceeds the illustrated 30 A housing marking; verify the supplied holder rating before fitting a 32 A fuse. |
| Original parameter-image current list | 3, 6, 10, 15, 20, 25, 30 and 32 A |
| Utilisation reference | DC-20B in written description; do not open under load |
| Mounting | 35 mm DIN rail; one module approximately 17.5 mm per pole |
| Temperature range | −40 to +90 °C, original parameter image |
| Housing | High-temperature resistant insulating plastic |
| Marking | IP20 on illustrated housing |
| Breaking-capacity reference | 30 kA in source image; a fuse/assembly reference, not a claim of standalone holder short-circuit interruption |
| Standards in source | IEC/EN60947-1 and IEC/EN60947-3 references on housing |
Pull-out fuse carrier
The carrier opens for fuse replacement after the circuit has been isolated. The housing explicitly states “Do not open under load”. A suitable DC photovoltaic fuse must be selected for the circuit.
Indicator window
The illustrated indicator version provides a red window for fuse-status identification. Non-indicator holders are also shown. Follow the status meaning and wiring instructions of the supplied version.
Holder and fuse supplied separately
The holder accepts a 10 × 38 mm cylindrical fuse link. The original reference shows both components, but this product listing does not include a fuse unless separately specified.
Insulated enclosure and markings
The side view retains the original electrical and use markings, including the no-load-opening instruction. Keep the fuse voltage/current rating within the rating of the supplied holder.
Original parameter reference
The source image preserves its current and temperature list and the 30 kA assembly reference. Fuse protection characteristics depend on the actual installed link.
Dimensions
The three-pole reference drawing shows 51 mm assembly width, 85 mm height and 65 mm side reference. The earlier single-/two-pole family drawing uses 18 mm and 36 mm widths; allow for the actual supplied assembly.
Single- and two-pole versions
The source illustrates one- and two-pole holders with and without an indicator.
Three- and four-pole versions
The multi-pole illustrations below show both indicator and non-indicator versions. Each fitted fuse must be appropriate for its circuit.
Non-indicator multi-pole reference
The original source also shows the non-indicator three- and four-pole assemblies.
Typical applications
Photovoltaic string and DC distribution fuse installations using compatible cylindrical PV fuse links. Mount in a suitable enclosure and isolate before opening the carrier.
