Kripal UKRT-18 32 DC FUSE & BASE 32A 690V

Description

Here is a description of the fuse type you asked about — the Kripal UKRT18/32 (sometimes listed as RT18-32) or equivalent series. You’ll need to check the exact model variant in your system to be sure, but this gives you the main characteristics.

🔍 Key Specifications and Features

• The model series “RT18-32” refers to a fuse link frame rated for 32 A in its class. For example, a catalogue shows: Rated current 32 A, rated insulation voltage up to 690 V (AC) for that series. Scribd+1

• For DC application: one listing shows “DC FUSE RT18-32 1000 V DC” with class of operation gPV (for photovoltaic systems). Energy & Utilities

• The fuse link size for RT18-32 is 10×38 mm (typical cartridge size) in many models. tengenglobal.com+1

• The series is designed for overload and short-circuit protection. kripal.com+1

✅ What this means for your usage

• If you have a “UKRT18/32” label it likely means you have a 32 A rating fuse in the RT18 series frame.

• If it’s used in a DC circuit (e.g., solar PV, battery, etc) you must ensure the fuse is rated for the required DC voltage (some variants mention 1000 VDC) and has the correct breaking capacity for your fault currents.

• It is important the fuse link (cartridge) matches the holder/base for this series (correct size, correct current rating) and that the holder is correctly rated for the voltage and environment.

⚠️ Things to check / watch out

• Confirm the voltage rating for the model you have. Some RT18-32 may be for AC 500/690 V. For DC usage you might need a variant marked “1000 V DC” or similar. E.g., one listing: “DC FUSE RT18-32 1000 V DC” class of operation gPV. Energy & Utilities

• Confirm the breaking capacity (i.e., how much fault current it can interrupt safely) — this is often less in DC rated fuses or higher depending on design.

• Confirm that the fuse is being used in the correct holder / base (the RT18-32 series base is specified at certain dimensions in the catalogue) and that it is installed according to the manufacturer’s recommendations. tengenglobal.com

• Ensure the environment (ambient temperature, altitude, pollution degree) matches the spec sheet of the device. The earlier data sheet for RT18 series shows ambient temperature must not exceed 40 °C etc. tengenglobal.com

📝 Summary

So in short:

• It’s a 32 A rated fuse in the RT18 series (cartridge style, 10×38 mm) — RT18-32.

• For DC use: there are versions rated for 1000 V DC (for PV/solar) with the class gPV.

• Make sure the exact variant matches your application (especially voltage and DC/AC).

• Good practice: check the manufacturer’s datasheet and replace with an equivalent rated part only.
