SCHÄFER IT SYSTEMS Termostato para control de ventilador, 0 a +60 °C, contacto conmutador, montaje en carril DIN, 6763000

Temperature-controlled ventilation often suffers from imprecise switching and unreliable contacts, causing fans to run too long or not at all. The SCHÄFER IT SYSTEMS thermostat for fan control solves this by providing a dependable bimetal switching mechanism that reacts to temperature changes with a defined hysteresis, ensuring fans operate only when needed.

Who is it for

This thermostat is intended for electricians, panel builders, and HVAC technicians who need to automate fan operation in enclosures, control cabinets, or other installations where temperature regulation is critical. It suits DIN rail mounting and simple two-wire connection.

Main features

• Adjustable setpoint from 0 to +60 °C
• Switching differential of 7 K (±4 K tolerance) prevents rapid cycling
• Change-over contact (SPDT) rated for 250 V AC, 10 A resistive load
• Thermostatic bimetal sensor requires no external power
• Mounts on 35 mm DIN rail with clip
• Connection via 2-pole screw terminals, max wire size 2.5 mm²
• Housing made of flame-retardant plastic (UL94 V-0), light grey RAL 7035
• Protection class IP20 for indoor use

Tips

Set the desired temperature using the adjustment dial. The thermostat will switch when the temperature rises above the setpoint plus the differential, and switch back when it falls below the setpoint minus the differential. Ensure the bimetal sensor is exposed to the air flow you want to monitor.
