Întrerupător limită de temperatură KSD301

KSD301 is a widely used bimetallic temperature-controlled Limit switch, mainly used for overheat protection or temperature control of electrical equipment. Its main features and information are as follows:

eu. Core Principle
KSD301 realizează controlul temperaturii prin elementul bimetalic de detectare a temperaturii: Când temperatura echipamentului atinge temperatura de acțiune prestabilită, banda bimetalica este deformata de caldura si actioneaza instantaneu contactul pentru a deconecta circuitul; după ce temperatura scade la temperatura de resetare, contactul se închide automat și reia puterea.

III. Specifications and Types
‌Contact Form‌
‌Normal Closed (NC): The contact disconnects when the temperature rises (most commonly used).
‌Normal Open (NU): The contact connects when the temperature rises.
‌Mounting Structure‌
Bent-leg/flat-angle terminals are optional (remarks are required when placing an order).
Enclosure protection level: IP00 (metal enclosure grounded).

Iv. Aplicații tipice
‌Aparatele de uz casnic‌: dozatoare de apă, mașini de gătit orez, dulapuri de dezinfecție, cuptoare cu microunde, Mașini de cafea.
Echipamente industriale: aer conditionat, laminatori, electric heating appliances.
‌Automotive field‌: diesel filter heating system.

V. Procurement and selection
‌Temperature marking‌: The required operating temperature (such as 85°C, 125°C) and contact type must be specified when purchasing.

Tip‌: The operating temperature tolerance and reset temperature difference must be confirmed according to the specific model. The tolerance of some high-precision models is as low as ±2°C.
