The FTD 011 is a tamper-proof dual thermostat with independent normally closed and normally open contacts in a single plastic housing, designed for separate heating and cooling control. It features snap-action contacts, clip-on mounting for 35 mm DIN rail, and operates within a temperature range of -40 °F to 176 °F. The part number 01163.0-02 has a switch-off temperature of 77 °F and a switch-on temperature of 95 °F. It supports switching capacities of 10 A at 120 VAC for resistive loads and 2 A at 120 VAC for inductive loads, with a maximum inrush current of 16 A for 10 seconds. The housing complies with UL94 V-0, and connections accept rigid or stranded wire up to 2.5 mm² (AWG 14) with a maximum torque of 0.8 Nm. Dimensions are 1.9 in height, 2.5 in width, and 1.3 in depth, weighing 1.4 oz.
Two thermostats in one housing:
Tamperproof (Pre-set) Thermostat NC (normally closed): Thermostat opens on temperature rise (red module housing) - for regulating heaters or for switching signal devices when temperature has fallen below the minimum value.
Tamperproof (Pre-set) Thermostat NO (normally open): Thermostat closes on temperature rise (blue module housing) - for regulating filter fans, heat exchangers, cooling devices or for switching signal devices when temperature limit has been exceeded.
