SCHROFF ETR201 termostat NO køling 0-60°C

Overheating inside industrial enclosures can lead to premature component failure and costly downtime. The SCHROFF ETR201 thermostat provides a reliable, mechanical solution for automatic cooling control, activating fans or heat exchangers when temperatures rise above a set threshold. With a simple rotary knob, you can adjust the setpoint from 0°C to +60°C to match your specific cooling requirements.

Who is it for

This thermostat is ideal for panel builders, system integrators, and maintenance engineers who need a robust, no-frills temperature switch for enclosure climate control. It is particularly suited for applications where digital controls are unnecessary or where a purely mechanical device is preferred for reliability and cost-effectiveness.

Main features

• Normally open (NO) contact closes on temperature rise, directly switching cooling devices up to 10 A resistive at 250 V AC.
• Wide adjustable setpoint range from 0°C to +60°C via external knob with clear scale.
• Compact DIN rail mountable housing (35 mm) for quick installation in standard enclosures.
• Thermobimetal sensing element provides consistent switching with a hysteresis of approximately 7 K (±4 K) to prevent rapid cycling.
• Robust plastic housing with UL94 V-0 flammability rating and IP20 protection for safe use in control cabinets.

Tips

To ensure optimal performance, mount the thermostat away from direct heat sources and ensure adequate airflow around the device. Regularly check the setpoint against your cooling requirements, especially after seasonal changes.
