Product Overview
Honeywell Clarostat VP-25-K is a fixed wirewound power resistor rated at 5 kOhm (5000 ohms) and 25 watts. Wirewound construction delivers stable, reliable resistance under sustained power loads - the reason this series appears in industrial control panels, motor drives, power supplies, and high-power prototype circuits where a general-purpose resistor would burn out. The ceramic body and radial lug terminals are confirmed by photo evidence on this specific unit.
Key Features
- Resistance: 5 kOhm (5000 ohms) - confirmed by photo markings (5K-Ω)
- Power rating: 25 watts
- Construction: Wirewound - stable under sustained load, suitable for demanding industrial environments
- Body: Ceramic - confirmed by photo
- Terminal style: Radial lugs with mounting brackets - confirmed by photo
- Stamped code: 411 8501 - visible on unit
- Fixed resistor - not adjustable
- Note: Wirewound construction has inherent inductance; not suited for high-frequency AC applications
Applications
- Industrial maintenance tech desolders a failed VP-25-K from a control panel or motor drive terminal strip and drops this replacement in - exact resistance and power rating, nothing to recalculate
- Power electronics engineer integrating a 5 kOhm, 25W resistor into a load bank or current-limiting stage during prototype testing, where a lower-watt resistor would fail before the test run ends
- Vintage amplifier restorer tracking down a period-appropriate wirewound power resistor to replace a failed component while keeping the original circuit behavior intact
- Hobbyist building a dummy load or voltage divider for bench testing - 25W handling gives headroom that carbon-film resistors cannot match
Frequently Asked Questions
Is this the 5 kOhm version or a different resistance value?
This is the 5 kOhm (5000 ohm) version. The markings on the physical unit confirm 5K-Ω. The model suffix "-K" in VP-25-K denotes kilo-ohms; the series is available in other resistance values, but this unit is 5 kOhm.
What are the terminal and mounting details?
Photo confirms radial lug terminals and mounting brackets on this unit. Buyers should verify that the physical dimensions and lug spacing fit their board or panel layout before ordering.
Can this replace a failed 25W resistor of the same value in my equipment?
If your application calls for a fixed 5 kOhm, 25W wirewound resistor and your mounting accommodates the lug and bracket style shown in the photos, this is a direct candidate. Wirewound construction is appropriate for DC and low-frequency AC circuits; it is not suited for high-frequency AC applications where parasitic inductance is a concern.
Does this come with any documentation or accessories?
No documentation or accessories are included. This is the resistor only.
The stamped code on the ceramic body has been sitting quietly for decades, waiting for the circuit that needs exactly 5 kOhm and exactly 25 watts. Yours might be the one.
