ETR202

Overview

The Hoffman Enclosures ETR202 is a compact heating thermostat designed for electrical enclosure temperature regulation. It features a plastic housing and operates with a normally closed (NC) contact configuration. The device supports a setting range of 0 °C to +60 °C, with a switching temperature difference of less than 7 K and a switching point tolerance of ±4 K. It is rated for 240V operation and includes overheat and short-circuit protection mechanisms.

Feature Summary

• Prevents condensation by maintaining optimal temperature and dryness within enclosures
• Provides safe operation through integrated overheat and short-circuit protection
• Allows quick installation via DIN-rail or screw mounting methods

Applications

• Panel temperature regulating for anti-condensation heaters
• Electrical equipment safeguarding in various settings
• Enclosure climate control applications

Procurement Notes

Verify the specific voltage rating and contact configuration against your system requirements before procurement. Confirm that the mounting method aligns with your enclosure design. Ensure the thermal characteristics match the environmental conditions of the intended application site to guarantee proper functionality and safety compliance.

Selection Notes

Select this model when precise temperature regulation between 0 °C and +60 °C is required for condensation prevention. Consider the NC contact type and 240V rating compatibility with existing heater circuits. Evaluate the compact size and dual mounting options for space-constrained installations where reliable thermal management is critical.
