The FZK 011 mechanical thermostat is a clip-mounted device for heating and cooling control, using a thermostatic bimetal sensor and a snap-action changeover contact rated for 230 VAC. It operates over a temperature range of 40 °F to 140 °F with a switching differential of 5 K. The device mounts on a 35 mm DIN rail and measures 2.6 in high, 2 in wide, and 1.5 in deep, with a UL94 V-0 plastic housing. It switches up to 10 A resistive and 4 A inductive for the normally closed contact at 250 VAC, and 5 A resistive and 2 A inductive for the normally open contact at 120 VAC, with a DC capacity of 30 W. Connection is via a 4-pole clamp for wire up to 2.5 mm² rigid or 1.5 mm² stranded. Protection rating is IP20. Operating temperature range is -49 °F to 149 °F.
The FZK 011 mechanical thermostat is used for controlling heating and cooling equipment, filter fans or signal devices where a higher degree of sensing accuracy is required. An integrated resistor (RF) can be connected to improve the switch temperature difference.
The thermostat registers the surrounding air and can switch both inductive and resistive loads via snap-action contact.
