FZK 021 Mechanical Thermostat
Features
■ Adjustable temperature
■ High switching capacity
■ Small hysteresis
■ Terminals easily accessible
■ DIN rail mounted
■ Change-over contact
The mechanical thermostat is used for controlling heating and cooling equipment, filter fans or signal devices. The thermostat registers the surrounding air and can switch both inductive and resistive loads via snap-action contact.
