NSPV‑38 Fuse Holder (DC 1000 V)
Overview: The NSPV‑38 refers to a fuse holder designed to accommodate 10 × 38 mm PV fuses at up to 1000 V DC. It typically includes a pre-installed fuse—often with a 20 A rating
Key Features:
High-voltage DC‑rating up to 1000 V for solar applications
Integrated fuse allows for modular protection and easy replacement
Robust design to handle high short-circuit currents in PV systems
General Characteristics (inferred from similar components):
DIN‑rail mountable, streamlining installation in combiner boxes
Typically designed to meet solar safety standards (such as IEC, CE)
Supports effective isolation of PV strings during fault conditions or maintenance
Comparison Table
| Component | Voltage Rating | Fuse Size | Typical Current Range | Usage & Features |
|---|---|---|---|---|
| NSPV‑25 Fuse | 1000 V DC | 10 × 38 mm | 1 A – 30 A | Overcurrent protection for PV strings |
| NSPV‑38 Holder | 1000 V DC | 10 × 38 mm | Often ~20 A | Houses PV fuse; supports easy swap and system isolation |
Summary
The NSPV‑25 fuse is a DC fuse tailored for photovoltaic systems, covering a wide range of currents up to 30 A and meeting gPV standards.
The NSPV‑38 fuse holder provides a secure mount for these fuses, enabling isolation and protection at 1000 V DC.
Both are well-suited for PV systems like combiner boxes, wiring harnesses, and protection circuitry inverters.
