ekd series

Series EKA: ½” Disc Thermostat

EKA series is a compact design, auto and manual thermostat for controlling or limiting temperature changes.

The switch mechanism is actuated by a snap-action bimetal disc, which opens and closes a set of electrical contacts when predetermined temperature is reached. The bimetal disc is electrically and thermally isolated from the switch.

Different mounting configurations are available for maximum design flexibility: surface mount, air-stream and duct mounts.

Used in boilers, heaters, vacuum cleaners, stoves, dryers, dishwashers and air conditioners.

Temperature range: -30C to 170C (-22F to 338F)
Contact rating: SPST contact with 16A@120/240VAC

Series EKB

Series EKB: 3⁄4” Disc Thermostat

The sealed design of EKB provides moisture resistance for high humidity environments.

Automatic reset for high and low temperature applications and manual reset for high limit temperature. The switch opens or closes its electric contacts on temperature rise.

Surface and tube mounting options with a wide variety of terminals, lead wires and mounting options provide excellent design flexibility.

Used in refrigerators, air conditioners, Ice makers freezers, as well as defrost termination and fan delay control.

Temperature range: -30C to 80C (-22F to 176F)
Contact rating: SPST and SPDT with 5A to 25A@ 120/240VAC

EKC-200, Description


EWD

Terminal C-L cut-in at temperature rise. Terminal L-H of auxiliary switch cut-out when the shaft turned to OFF point. Terminal C-L can be cut-out at OFF point, and can be forced ON at ON point. The ON temperature is constant at any position from Warm to Cold, the OFF temperature is adjustable. This behavior assure an automatic defrost function.

The WD-R series with an internal bellows heating resistance connected to C-L, is able to be used at cross-ambient in a refrigerator.

Constant cut-in temp, range: +2~+8°C

Available OFF temp, range: -36—4°C

Adjustable temp, range: Max.l9°C

Differential: Min.8°C
