The ETI GPT-3 Freeze Protection Thermostat is designed as an ideal alternative to electromechanical thermostats and high cost single and multi-channel temperature controls. The thermostat has a set point temperature range between 41F and 77F (5C and 25C) which is an ideal range for freeze protection applications. Calibrated control temperature setting Built-in GFEP with programmable automatic reset Continuous monitors either constant wattage or self limiting heaters Automatic supply voltage selection, 120 to 277 VAC Alarm relay with isolated contact Two-pole contactor up to 30 AMP heater loads NEMA3R enclosure C-UL-US
The GFEP uses digital filtering to minimize false trips. Although preset for 30ma, the GFEP can be set to trip on currents as high as 120 mA to avoid nuisance tripping on longer cable runs.
