KSD304 Bimetallic Thermostat Thermal Cut Off Switch with 100000 Cycles 250V 16A and -10~300°C Temperature Range

The KSD304 thermal cut off switch utilizes a bimetallic disc mechanism for reliable snap-action temperature control. This thermostat provides precise temperature regulation with durable construction for various industrial and household applications.

The KSD series thermostat functions through the snap-action response of bimetallic discs to temperature changes. This action activates internal contacts to open or close circuits, featuring fixed working temperatures, reliable operation, minimal flashover, extended lifespan, and reduced radio interference.
