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

With a high current capability switch of SPST or SPDT. There is a narrow differential and a forced OFF function. This kind of thermostats can be used in direct current (DC) with inductive loads.

WK-B and WK-C series with bottom outlet terminals are available.

Thermostats with a fix operating temperature(without a shaft) for air conditioner defrosting are also availabe.

Available temp, range: -35~+40°C

Adjustable temp, range: Max.20°C

Differential: Min.2°C

Terminal C-L Cut-in at temperature rise. With SPST or SPOT, and an additional auxiliary switch. There are forced OFF and/or PD points. Type WP-T with two-spring mechanism is a wide differential range.

Available temperature range: -36~+15°C

Adjusting temperature range Max.25°C

Differential: WP(5~14°C) 5-25 °C WP-T (10-25 °C)

Terminal 3-4 closes at temperature rise

In general type KP is classified into 2 basic versions:

Version A: KP with standard switching differential

Version B: KP with wide switching differential

Rating at 250 V 50 Hz

3-4: 6(6)A

Temperature control with S.P.S.T. switchand auxiliary switch for off position. Automatic defrost function by constant cut-in value

Terminal 3-4 closes at temperature rise

Terminal 3-6 opens in OFF position

Constant cut-in thermostats for explosive area.

This is a special designed type with SPST switch plus an aux switch. It is an "n" type apparatus in accordance with the standard IEC79-15. It can prevent the possible explosion when the switch body is located in the explosive gas mixed air. Ex approval of China was obtained and VDE Ex test was past.

Maybe with an internal bellows heating resistance connected to C-L terminal to enable to be used at cross ambient in a refrigerator.
