ETF200

Overview

The ETF200 is a hygrostat manufactured by nVent Hoffman designed to control moisture levels within electrical enclosures. It operates with a switch capacity of 250 V AC, 5 A DC, and 20 W, with the ETF2000 variant supporting up to 30 W. The device housing is constructed from plastic rated UL94 V-0 for fire safety. This component functions as an environmental control sensor to prevent condensation.

Feature Summary

• Functions as a hygrostat to manage enclosure humidity
• Constructed from UL94 V-0 rated plastic material

Applications

• Control of moisture in industrial electrical enclosures
• Prevention of condensation in control panels

Procurement Notes

Verify the specific part number suffix when ordering, as the ETF2000 variant has different power ratings compared to the standard ETF200. Confirm that the required switching capacity aligns with the 250 V AC, 5 A DC specification. Ensure the application environment is compatible with the UL94 V-0 plastic housing material. Cross-reference the official nVent Hoffman datasheet to confirm compatibility with existing enclosure mounting requirements.

Selection Notes

Select this component based on the need for passive humidity control rather than active cooling. The ETF200 is suitable for applications where condensation prevention is critical but thermal load management is secondary. Consider the 20 W or 30 W power rating depending on the specific variant required. Evaluate the enclosure size and expected humidity levels to determine if a hygrostat is sufficient versus a heater or cooler.

Part Context

The ETF200 belongs to the nVent Hoffman line of environmental controls for industrial enclosures. It is distinct from mechanical hole seals like the AS100SS series, which serve sealing purposes. This product is part of the broader Hoffman portfolio focused on protecting equipment from harsh environments through moisture and temperature management solutions.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing wiring and mounting configurations before considering alternative models from other manufacturers.
